[00:02:23]   hey friends my name is Aaron Ciotti everybody calls me Ciotti welcome to the show it looks like I'm high I've just been up all night I assure you you I got really behind on work

[00:02:35]   because of my back exploding and last night my brain was like oh look you're you're good enough to sit at your desk again you have to get all the work done or else I'm going to kill you because I'm your

[00:02:49]   brain and I'm an idiot sometimes but I got a lot of work done last night so it is what it is and in the process the the beginning of that manic episode

[00:03:03]   basically was a little bit of a sort of Revelation the basically in spinning a bunch of Motors up with the props off I realized that the KVs stamped on these motors are not super accurate

[00:03:29]   that's not the important part though the important part was then realizing that with bidirectional dshot I can spin these tiny whoop Motors up with no prop on and then I can spin

[00:03:42]   them up with a prop on and I can look at that differential well so so to get the KV of the motor previously I didn't think we could do this because the 8bit esc's have a maximum RPM limit and

[00:03:57]   these like 30,000 32 2,000 KV and up Motors without a prop on exceed that limit but we don't have to go to 100% it's most accurate when you do it at 100% I also talked to Ryan Harold a

[00:04:14]   bunch yesterday about a about all this stuff just to make sure that I was on the right track and KV measurements are best done at Full Tilt but we can't do that because of the

[00:04:28]   limitations of the 8bit yes C there are other ways to test the KV but this method is is relatively accurate and kind of just as almost as good we just don't we just do 50% throttle take

[00:04:43]   the prop off go into BetaFlight 50% throttle on the motor's tab that will not exceed the limit of the 8 bdsc and that'll give us a number that we then just double and then we do the KV

[00:04:56]   math but I don't even necessarily care about the KV all I care about is that number that RPM that we get with the prop off all right so no load on the motor we're going to get a an RPM that it's

[00:05:15]   that it's wound to turn and then we're going to put a 1210 GemFan by blade on there and we're going to crank it up to 100% the propeller creates enough drag that the

[00:05:27]   motor will not exceed the hard limit that the esc's have that the apid esc's have so then we've got the unloaded maximum rpm and then the loaded down with a prop on it maximum

[00:05:42]   rpm the the gap between those numbers is going to tell us how much work the motor can do you can and it's also going to clue Us in on the efficiency of the motor and so I've

[00:05:56]   got a whole bunch of stuff ready to do some testing today anybody that wants to I can give you the whoops I can give you the share the link to this spreadsheet that I've got going

[00:06:14]   because it's spreadsheet Sundayand we're going to take a look at a whole bunch of Motors at what they'll what the RPM they'll turn spinning freely and then with the prop on and

[00:06:29]   what I think that we're going to see is that the gap between those two numbers is going to be the smallest with HappyModel Motors we've always kind of noticed that HappyModel tiny whoop

[00:06:41]   Motors just seem to make more power and they're more efficient and I think doing this is is going to I think this is going to kind of show us that because you can wind a motor to turn a

[00:06:58]   million KV but if you don't optimize the thickness of the windings which we've been talking about a ton it's not going to make a lot of power like it'll just turn a lot of

[00:07:08]   KV when there's no load put on it but as soon as you drag it down it won't have the it won't have the amount of copper that it needs in the stator to actually push that propeller through and

[00:07:21]   and we're also going to see that on the different motor sizes like on a 702 there's probably going to be a much bigger gap between the the unloaded RPM and the loaded RPM

[00:07:33]   whereas when we get up into like 802s we're we're going to test an 803 I'm a little bit Limited in what I can test because I want to do it all on the the GemFan 1210 propeller and

[00:07:47]   that's only a 1 mm motor shaft so we can't really test any of these 1 and a half millim shaft Motors unless we go to a 16 I guess we can we can just have a separate set

[00:07:58]   of testing with the 1610 propeller that's fine but I think this is going to really clue Us in so that we can like take a look at these VCI Motors take a look at I have some newbie

[00:08:09]   drone Motors here some 29,000 KV newbie drone Motors that we can test and then we can compare those to HappyModel look the the optimizing the thickness of the copper winding material on the

[00:08:23]   Stater is only one of many things Ryan Harold was was he was very quick to make sure that I remembered this and I did and we've talked about this right when when you compare like a HappyModel

[00:08:35]   motor to oh I also have BetaFPV Motors that we can test so when you compare a HappyModel 32,000 to a BetaFPV 32 hold on what what's the KV of the BetaFPV motor is it

[00:08:50]   32 I'm actually really excited to test no no no no the beta the beta motor is 27 so I won't be able to have a direct test but what I think I think we're going to see is that like I

[00:09:03]   said that that differential is going to be bigger but Ryan made sure that I I remembered that there are other things at play strength of the magnets air gap flux ring outside of the

[00:09:19]   magnets to try to keep the the the magnetic field inside the motor so those things I guess we'll we'll get to see those things as well so we're not just calculating here like whe how good of or

[00:09:37]   bad of a job they did at optimizing the thickness of the copper we're kind of testing everything how strong are the magnets how tight is the air gap how good is the flux ring and there's a

[00:09:49]   bunch of other stuff but I think this is really valuable kind of stuff because the smaller that gap between these two two numbers the better the motor the more work the motor is able to do and I

[00:10:01]   and I'm pretty sure it also is how efficient the motor is so this will be pretty cool there's a Facebook group where that's kind of really spawned all of this in my brain over the last

[00:10:16]   month or so where they are hand winding tiny whoop Motors and they're starting to figure some of this stuff up butterfly FPV has been taking apart tiny whoop Motors and measuring the thickness

[00:10:27]   of the windings and how many turns are on each stator and so this is just hopefully GNA help even more with that what what we're trying to find out is what where are the

[00:10:40]    what's the best tiny whoop motor Chris roster has some testing coming out that'll that'll also really beef this up with his really fancy thrust stand and so I have a feeling that

[00:10:54]   between what we're going to do here today Chris's video that's coming what the guys are doing over on the hand finding tiny whoop group I feel like we'll have a better handle on what

[00:11:07]   how high is to high in terms of KV are there any is there like is there a KV where where we get stuck in between the thickness of windings so so like for example one of the things that

[00:11:21]   I see the guys in that group running into is that like if if they're using like. 21 of a20 mm winding material the next jump is like .25 and there might be a KV that

[00:11:37]   falls in between those two where it's not going to be optimized because there isn't a thickness of a winding thickness between 0.20 and 0.25 right just as a random example and so if we find

[00:11:51]   that like 30,000 34,000 KV Falls in between there then we know like maybe skip the 34,000 KV motor and either get 32 or 36 right that's kind of what I'm hoping to see here and

[00:12:08]   I'm also hoping to kind of debunk the whole thing where like it really seems like BetaFPV and VCI Motors to name the two that have I've noticed this recently their Motors make less power and are

[00:12:20]   less efficient for the given KV and so we know that those Motors are buy them if you like the color of them but maybe stay away from them although there are other benefits of

[00:12:34]   those Motors I think potentially strength right I've not noticed this because I've mainly run HappyModel Motors but people that know what's what have said that the the the metal that

[00:12:48]   HappyModel uses for its motor shafts is not as strong as some of the other brands also the weight of the motors Brent Anderson said weight of the motor major to final

[00:13:01]   numbers right so there are other reasons to get these motors right now we are just going to be looking at like sort of the amount of work that the motors can do the other thing that this test

[00:13:14]   doesn't the other like shortcoming of this test is that I'm going to be holding these tiny whoop frames and so that is not the same as when they're in the air so the super high AV Motors are going to

[00:13:30]   be are not going to perform as well in these tests as they do in the air but that's okay because mainly like in this we're kind of looking for one brand versus another brand do HappyModel

[00:13:46]   motors have a smaller differential in the unloaded RPM versus the props on loaded down RPM than some of these other Motors and I have a feeling that that's what we're going to see and I

[00:13:59]   I I I think what we're also going to see is that that gap between those gets bigger and bigger and bigger as the KV goes up we should see that that that wouldn't it's going to be drastic

[00:14:12]   because I'm going to be holding on to the rig there's no incoming air I'm just just like a loaded thrust in and that's the data that we're going to get from Chris Rosser and his testing too

[00:14:22]   and and so in Chris's testing I can all but guarantee you that it's going to look like the high KV Motors I'm talking like high high like 30,000 32 36 40 if he tests Motors that are

[00:14:36]   that high of a KV they're going to look like they get super inefficient and that's mainly going to be because it's a loaded thrust stand with no incoming air those Motors

[00:14:48]   are more efficient in the real world when you're actually flying them as we've shown on the 40,000 KV Motors I'm still getting over 3 minutes of runtime I get pretty much the same

[00:14:55]   amount of runtime as I do with 32,000 30,000 so there you go there's 20 minutes of information right off the rip for you that's the plan today it's spreadsheet Sunday friends thanks

[00:17:31]   does that mean it looks like Texas UAV Force joined twice you can do that if you want to get two entries into the giveaway you can just join twice I don't know if that's what happened or if the email

[00:17:42]   maybe doubled in some weird way but thank you regardless brother Caleb shillow welcome to gangly gang gangly gang verb balance thank you for joining my friend thank you for the support

[00:17:54]   George ramstead welcome to the gang friend Jeffrey Hathcock thank you for the support dude gangly gang for Life Allan C Stephen P I'm just going to say instead of massacring your last name thank you

[00:18:09]   friends for the support and there is my BetaFPV order so I'm caught up there we go my BetaFPV order shipped yesterday so let's see how long it takes to get here

[00:18:24]    it's been a long time since I ordered from there I don't know where it's shipping from hopefully it doesn't take weeks because the 2S WalkSnail tiny whoop AIO is on that order and I want

[00:18:36]   to get that thing back up in the air thanks for joining friends it really does mean a lot that you jump onto the patreon hopefully it's worth it I feel like I see more people join than

[00:18:47]   leave so that's a good thing but first and foremost I I greatly appreciate the support it means a lot it is literally the only reason that I can continue to do this full-time and

[00:18:59]   stay up all night Marquez unread yes yes yes yes yes I want that to be unread all right speaking of my email AliExpress don't send me emails there we

[00:19:16]   go an email entitled inverted ball sack canopy Cloud Hopper thank you for that brother I don't want to show your email address perfect I figured it out what are you saying discovered you can save

[00:19:32]   nearly 02 grams if you shave your ball sack I have some laf frame Zoo to deliver suum sub 18 gram range with connector Motors on a 65mm I have also seen people cut the ass off of

[00:19:49]   this Frame they cut from they cut like like here they cut this whole part this whole back part of the damn thing off and Works totally fine I have never really fully broken one of these

[00:20:06]   things but I don't know if I'll do this this is super interesting I I'm sure that this does work but I break these things up here on the top and then eventually well

[00:20:20]   actually no I've never broken one of the ones with the forward I used to break these frames the old school version that didn't have this forward Ward mounting point I used to break them on the bottom

[00:20:30]   here below the camera and then I'd break them on the top and then it would get kind of wobbly but now that now that they have this front support and the the camera screws in right here and so

[00:20:45]   I wonder what the I have enough of these damn things where I can I can start to kind of screw around with them I think what I should do is cut the ass off of one so that what we're looking at here

[00:20:55]   saves 02 of a gram Cloud Hopper says which is very cool so you cut this part out open up this front open up these top two and then open up these back two here I'm going to cut the ass off of one

[00:21:09]   and we'll see how much weight that saves I bet you it saves you even more weight and then we can shave your ball sack 10 out of 10 my friend thank you for the for the

[00:21:26]   Super Chat brother if if you want to talk to me in the chat all you got to do is type CiottiFPV you can do a super chat if you want to be cool like Cloud Hopper you can all just also just

[00:21:35]   type CiottiFPV you don't have to put an at in front of it but you can if you'd like cloudops first ctis Hayes notice or or FPV Northern Tier FPV toast Kevin Sumer Caleb shillow smoka

[00:21:49]   dog Kujo Kevin are you GNA be somewhat actively never mind I I'll I'll talk to you after after the stream I'm making a spreadsheet on the stream I'm wondering if you can

[00:22:04]    if I'm wondering if you could put like a formula or two into it because you seem to know spreadsheets pretty damn well to figure out the the differential between these two

[00:22:16]   numbers but we'll figure it out I think we just need to divide the bigger number by the lower number to give us like this this number that will that will will

[00:22:30]    show us the the distance between RPMs loaded versus unloaded Caleb shillow Smoking Dog Kujo Cloud Hopper Douglas outwell cisal FPV cman FPV kilo zebra Striker

[00:22:44]   Douglas otwell again Hendrick Freakazoid Colin sableton Striker what's up everybody thanks for coming let me get caught up on chat and then we'll start spinning Motors up

[00:22:55]   Striker says what do you think is the best slightly larger motor for 75mm 82.8 RC and Power 102 it depends on a lot of things Striker it depends on the all up weight it depends on like it

[00:23:10]   depends on a lot of things and I don't really have an answer for that yet if it's WalkSnail if it's an analog 75mm rig the ow 802 27,000 I think are are the best but bigger than that I

[00:23:26]   don't know yet ch3 says what's up Walter says Orie FPV says you talked about Mobula 6 2024 having an issue with the camera or canopy and many people were destroying them after a couple batters

[00:23:40]   do why thank you I think it's because of the the stupid g string camera mount setup that they've got mine has been completely indestructible even with me flashing the

[00:23:51]   wrong firmware and screwing it all up it's come back to life and I I very early on I switched mine to the old school Mobula 6 canopy and RunCam nan3 and it's been completely

[00:24:06]   indestructible and so I think that the stupid g string canopies are the reasons that a lot of these new tiny whoops are dying although I will say the g string canopy on the BetaFPV air 65

[00:24:19]   it puts the camera up so high that it seems to be fine I battered the hell out of a couple prototypes that they sent me and they were super durable so the air 65 is looking pretty good

[00:24:33]    Sprout says do you have a good analog build for a 2S 2 in drone that can fly like in a backyard or a park I don't yet Sprout I haven't gone down that path in about eight years but I

[00:24:47]   will soon I'm diving more into 2S give me like a month or two I got some cool stuff coming Moss one says I switched Motors on the new mobu 6 to the beta 0702 SE and it flew Twitchy for a

[00:25:01]   bit then run away into the ceiling what do you think the issue is it could be so many things Moss it could be bent motor shafts it could be bent propellers so first things first put a fresh set of

[00:25:12]   propellers on it and then I've shown a bunch of times how to see if so just go into Turtle mode and spin each motor up gently while you're holding the quad see if there's one motor that's

[00:25:24]   vibrating harder than another if it has a fresh prop on it then the motor shaft is bent you got to replace that motor could have been there those are the the most

[00:25:35]   likely things but the the pids also could be too high if if the beta you didn't tell me what the KV of the motors were if the BetaFPV Motors are a higher KV then you

[00:25:48]   probably need to back the pids off a little bit easiest way to do that is to grab the master multiplier and just pull it to the right by a couple of by like0 2 or3 so those are the most

[00:25:59]   common brand Anderson says but what we talked about that CMYK sayswhat's up gangly gang what's up homie Andrew Taylor says glad to help out but please get some sleep I wish if it were that

[00:26:09]   easy I would Kevin summmer says I'll take a break from no man Sky to set that up send me a link in Discord to the sheet thank you dude are you playing on the on the new I think I saw there was

[00:26:23]   a new Bing Bong a new update motor torque production yay okay how do I hold on so if I go back to docs and go I can take this and where's recent documents

[00:26:55]   no where is it where are you recent document how do I share this man I have I I have lost the the ability to computer in my old age share there we go share quick sharing actions copy link nope not

[00:27:10]   private I don't want it to be private I want it to be that and then copy the link an editor there we go okay cool done and copy the link there it is all you got it my friend

[00:27:30]   there it is it's in Discord Kevin I I explained this to you yesterday I believe so I I think you what we're trying to do here right I made another column for

[00:27:42]   1610 so let's let's get to testing but first we'll get caught up on chat thank you Kevin by the way spok dog kuo says my air 65 shipped from BetaFPV on 714 USPS is awaiting the item

[00:28:00]   from the shipping partner as of 801 almost a month what I wonder if they sent all of them out to the resellers and didn't send any out to customers that

[00:28:18]   sucks I would be pissed if that were me because you can just get one well maybe not I don't know I I got the Prototype so I don't know if PE have have has anybody actually gotten their

[00:28:30]   air 65 yet CL Hopper says I seem to remember you talking about Crash recovery at some point but I can't find it do you change default crash recovery settings I do I do here's

[00:28:43]   what you want to do though because my settings are different the the the crash recovery settings like the G thresholds and the timing and there's and there's also like a d there's a g

[00:28:56]   like gForce threshold and there's a Dain threshold you want to set those you want to set those for yourself and so here's how you can understand them a little bit better you Google

[00:29:14]   BetaFlight Wiki and then you come in here and you use the search in the top right I think I'm in the right spot wait wait no no no no no I want to go to well let's try it in the top right

[00:29:27]   corner you search for crash recovery it's worth it to just understand yep yep yep yep yep yep so do that Google Google BetaFlight wiki click through to the BetaFlight wiki that's

[00:29:43]   going to be the first search result top right corner search for crash recovery and it'll scroll you down and this is what you just need to read through and this is this is

[00:29:59]   you'll be able to understand this and then it tells you all the different fields and you can go in because what you don't want is Crash recovery to turn on too often or not often enough and

[00:30:11]   that's why you need to that's why you need to kind of read through this but you'll get it you'll get it's not super hard to understand and if you have any questions let me know

[00:30:28]    don't need that here's this there we go all right Moss one says thanks buddy you're certainly welcome noce says I love the spreadsheet crap I'd be happy to help with data entry if you need it I think

[00:30:44]   it'll be all right it's looks like I just needed this this one I think looks like Kevin's already done it God that was quick I had a feeling he might be able to bang it out super quick

[00:30:56]   because spreadsh stuff is not super confusing to people that have functioning human brains thank you again Kevin Cole power says they're probably short stocks from all those guys that bought it at

[00:31:11]   the $5 list price right Professor Byer Hazard says I ordered my air 65 715 just cleared Customs on 731 still awaiting delivery wow okay so it looks like the air 65s

[00:31:24]   this will be interesting because I don't have an air 65 in my order I just have a bunch of stuff that was in stock so we'll see all

[00:31:39]   right let's get into some testingso the other thing that we can test here is if different aios I'm kind of curious about this I think I have a couple of different aios here

[00:31:58]   with a couple of different W sorry different aios with the same Motors bolted to them and I want to check that I want to make sure that like one aiio is not going to turn

[00:32:14]   a different RPM than another with the same kind of motor as long as they don't in theory you guys can kind of add to the testing the problem with that is going to be I'm

[00:32:26]   going to be using my toolkit RC p200 adjustable power supply here locked at I want to say 4 Vols is the right number hold on I feel like 4 volts is the right number because a fully charged battery a

[00:32:51]   fully charged 300mah battery at 4.35 volts as soon as you power the quad on it sags down to 4.2 and then as soon as you take off it sags down to like four sometimes even lower than four it

[00:33:05]   depends on how fresh the battery is though like I've seen them sag all the way down to 3.8 as soon as you take off I don't want to power this at a so this power supply is not going to Sag

[00:33:17]   like these batteries right it'll be able to provide four volts or I could technically set it to 4.35 volts but setting it to 4.35 volts is going to really stress these esc's out and like

[00:33:33]   why do that if if in the real like we don't have any batteries that can actually do that so why do it here right I'm tempted to maybe set the voltage to 3.8 but I think maybe if you have

[00:33:50]   like a brand new fresh battery and you're running like lower KV Motors like 20 9,000 28,000 I feel like in that scenario the these batteries would be able to support 4 volts at Full Throttle so and it's

[00:34:09]   a nice round number right and so as long as we pick a number we'll be okay but I would love to like test every single motor in this way but I don't know I have an awful lot of Motors so

[00:34:23]   I'm going to set this power supply up 4 volts hopefully if you have a fresh battery and you want to compare your your Motors that you've got there if you've got a different KV different

[00:34:35]   motor size than me hopefully you'll be able to Kevin's still working on it thank you dude I see things moving around over here in the spreadsheet maybe you can get in on that but I

[00:34:52]   don't actually think that matters that much I I think the a consistent voltage is going to matter though so it's going to be tough I think if you want to get in on the testing you

[00:35:04]   would need to like charge the battery up do the testing real quick I'm going to show you how to do the testing in a minute and then put the battery back on the charger while you're changing to

[00:35:12]   a different motor and then wait until that battery is all the way up to 4.35 again put it on do another set of testing I think the best way to do this testing is to put two Motors of

[00:35:25]   each kind into the build so you can fire one up fire the other up take an average of the two fire the different KV up fire the different match of the different KV up take the average of the two and so

[00:35:39]   that that's what I've done here this is a build that's been just kind of Sitting Waiting for a canopy and Camera and this was what I was starting to screw around with yesterday that that put

[00:35:52]   me on this crazy when the lightning bolt struck my brain this is what I was messing around with so let's let's dive into it bad says our HappyModel ex 1404 4800 KV too much for a 249 gram 4S build

[00:36:10]   as the product description says 3s nope not at all it's probably going to be a really good motor although like if you already have that motor by all means go for it but what I can tell you is that

[00:36:21]   the t- 1404 4600 KV is kind of like the king of the 144s so if you haven't bought Motors yet and if the t- motors are available for whatever shop you're ordering from or

[00:36:35]   wherever you are in the world I would opt for the t-motor 144s rather than the happy models but apparently the HappyModel 144s are pretty good I think they're they're a little bit more

[00:36:46]   efficient I believe than the t- motors but I think they don't make quite as much power Rosser did testing on a bunch of 144s and both of those Motors are in his testing so you can check out

[00:36:57]   if you want all right I'm going to start adding to this spreadsheet the first two Motors that we're going to test are wait till you see how this plays out this is what blew my mind yesterday

[00:37:18]    tiny whoop Slappy model all right look for the rest of this video Tiny whoop Motors I'm just going to call HappyModel Motors because they're made by HappyModel wee bed and Tiny whoops

[00:37:31]   Motors are made by HappyModel cool you pretty much all know that but anybody that's new now HappyModel 0702 36000 and then newbie drone 0702 I got to double check 29,000 KV

[00:37:53]   Motors these KV numbers that I'm giving you are what's marked on the motor all right and you're about to see some wild [@$#%] this motor says 29,000 KV this motor says 36,000 KV okay that's what

[00:38:11]   we're about to do so let me let me pull this spreadsheet over here and I guess I can make it a little bit bigger and so NBD 0702 29 K right just double checking 29 Yep

[00:38:41]   they're both 29 all right so I'm going to pull the propellers off well no the propellers are already on so we'll do the props on test first and then I'll pull them off it's kind of weirdly out

[00:38:51]   of order versus the HM 0702 36k all right and so here's the test setup plugging it into USB so that we can fire up BetaFlight plugging in bt2.0 to a power supply set to four volts it's

[00:39:25]   going to be a consistent four volts for all this testing that's important all right that's plugged in and then I'm going to handhold I'm going to hold the the the tiny whoop when I do the

[00:39:43]   actual testing to give it a little bit of air flow down below so just kind of hanging it off the edge of the desk here just for the for the moment and

[00:39:55]   then and we're going to back some of this stuff up with different aios make sure that one AIO is not drastically different than another I actually have not tested that before so that should be

[00:40:08]   super interesting Brandon says I was under the impression that AI limits Motors to the to the lowest KV once plugged in the PID Loop does that yes but the the motors tab does not do

[00:40:21]   that the motors tab will just give you what you ask it for so if you if you you ramp a motor up to 100% on the motors tab it'll just send 100% to that motor it does not

[00:40:33]   involve the pit Loop so we're connected to BetaFlight we're going to go into the motors Tab and the and the the key is that the motors tab gives us back this RPM data

[00:40:44]   right bidirectional dshot gives us fairly accurate RPM data it moves up and down so fast that we're just going to take an average but that's okay because you're going to see the the differential

[00:40:57]   is is pretty big between these these loaded and unloaded RPMs that we're going to see all right so I'm going to push the button to fire up the power supply I'm going to try to do the

[00:41:09]   testing sort of as quick as I can so that I can get the numbers onto the spreadsheet before the AO gets too hot I don't want the AO heating up to affect any of this stuff so I'm going to

[00:41:23]   try to kind of do this fast and if you have questions just ask them on the chat I I hope that I've explained this good enough that everybody kind of knows what's going on here if not by all means

[00:41:32]   ask it in the chat I do oh I forgot this about the power supply the power supply struggles to fire these quads up for reasons that I never did figure out in the

[00:41:55]   past oh sh [@$#%] can you hear it oh no I forgot all about this [@$#%] [@$#%] I did have a little bit of luck damn damn damn damn damn damn oh I totally forgot about this I was

[00:42:46]   doing the testing yesterday with batteries because I didn't have the the cable that I needed let me try to put a capacitor on the the battery lead let me put a capacitor on

[00:43:05]   here all right hold on hold on I might i' I had a hunch last time and I didn't really test it but now I'm going to test it I I think this might work or it might

[00:43:23]   explode we will find out together I'm going to take a big old capacitor and so if I solder this guy here no I'm going to take oh good I've got a beat up capacitor

[00:43:51]   Perfect all right so I'm going to take a beat up capacitor and then I'm going to solder these guys to the capacitor and then this plugs into the battery and then there's a capacitor in

[00:44:06]   line and maybe just maybe that'll help oh I totally forgot about this oh my god oh boy I mean if we have to do the testing with batteries we can

[00:44:27]   but using the power supply is obviously going to give better results hold on I'm just thinking through this for one more second actually I'm going to use one of

[00:44:40]   these I'm going to use this guy because this also has the little Spike absorber thing and I have a weird hunch that that might have to do with that might be a part of the reason that the the

[00:44:50]   power supply is having trouble I don't think this will blow up right as long I I can put a capacitor here in this and then just clip the clip the leads here and it'll be fine right this won't

[00:45:07]   explode I don't think we're about to find out together right all right hold on let me clear up a space here these are the VCI 82.8 that should be cool

[00:45:27]   looking forward to testing those so let me just strip a little bit of wire off here and then I'm just going to janky solder these together and maybe this will fix the problem maybe it'll explode maybe

[00:45:45]   it'll fix the problem either way you guys will have a blast okay so I'm doing a janky but not janky inline capacitor let's put some flux on the wires all right there we go and we're

[00:46:16]   going to take our thermally resistive putty smash that on in there I'm going to assume that black is negative and white is positive all right and cool so let me tin this guy up

[00:46:38]   first come on piece of solder sitting on the thing help me there we go okay so let's just real quick end this and this look at all that flux burn it off all right good and so

[00:47:04]   now I'm just G to take this guy and this will actually help I'm using like alligator clips on this and this will help me keep that all together keep the alligator clips from touching one

[00:47:26]   another basically all right hold on I gotta I gotta tin the the back part of these wires hold on I'm just going to do it off the side of the desk real quick this doesn't have to be pretty it

[00:47:44]   just has to be strong enough to sit on the desk as I plug it and unplug it a couple times all right that should be good so then we're going to take the ground and I'm purposefully kind of

[00:48:00]   hanging it off the front here so that I can clamp the so I can clamp the little alligator clips to it so again it's going to look like ass but it's going to

[00:48:15]   work oh boy okay there's one and then here comes the other okay that's nice and smooth so it's going to be fine again it's going to look like ass but we'll be

[00:48:36]   fine I don't even know if this will help th this very well might do nothing but it's a hopefully a quick fix damn I completely forgot about the the power supply

[00:48:58]   being kind of a jerk last time I tried to do something like this all right so there we go we got those connected kind of janky but it'll work red is going to white black is going to

[00:49:14]   Black cool let's see if this explodes first thing I'll do is just clamp the so I'm going to turn off the voltage from the power supply and then I'm going to clamp black

[00:49:32]   to Black and then I'm going to clamp red to Red okay I'm going to hit the button hopefully the capacitor doesn't explode oh we're good all right it's on 3.9 raise it up to

[00:49:50]   4.0 okay all is well I'm going to turn it back off now I'm going to plug it into the AIO and hopefully I'm now not going to blow up a perfectly good 2g4 let's

[00:50:09]   see I am genius I am genius there is no one more genius than me look at thatI can't believe that worked I was certain that that wasn't going to

[00:50:23]   work so I just I I I just put a capacitor in line that's smoothing out the the flow of electricity from the the you would think that the what I think is happening the the adjustable

[00:50:37]   power supply has a it's it's like tripping it's got like a fail safe built into it and I think it's like tripping that fail safe I don't know I don't know what's actually happening but

[00:50:49]   it doesn't matter because it worked cool so now I just need to plug USB back in so back to our reg regularly scheduled spreadsheet Sunday although I will turn the side

[00:51:04]   iring iron off I see some chat comments give me a minute I am I'm doing sciency things all right so we can just fire this thing up now this is good to go it's hanging off the side of the desk

[00:51:19]   let's get it connected to BetaFlight and come into the motors tab we will fire up the whoop and now Motors one and three are the Newbie drone 29,000 Motors 2 and four are the happy

[00:51:40]   model 36,000 this is with props on ready motor one which is newbie drone let's see what the full oh boy I'm holding the oh no it's hitting the battery lead hold up I got to pull this off the

[00:51:56]   desk a little bit there we go that's better all right motor one newbie drone prop on and one of the things I'm looking for is up here up here is the the voltage that the

[00:52:13]   board is getting even on this power supply I can see that oh it's also noted right here so watch this watch right here oh hold on understand the risks all right so what watch this voltage sag even on the

[00:52:27]   even on the power supply it sags 38 it sags down to 3.8 so that's kind of perfect so this is what we're looking for here is the RPM ready I'm going to do all four of these I'm

[00:52:38]   going to do motors one and three the Newbie drone 0702 29,000 so that's basically 60,000 RPM it moves around but we're just getting an average 60,000 60,000 see it right so 60,000 is

[00:52:56]   the newbie drone with the prop on 1210 newbie drone here so 60,000 there we go and then we're going to look at the HappyModel and that's Motors 2 and four ready motor 2 65,000 motor 4 64,000 average it

[00:53:27]   out to 64,000 64 comma 00 to be expected right we've got 36,000 KV motor that's pulling 64,000 RPM 29,000 KV motor that's pulling 60,000 KV right this is what we expect to see the

[00:53:46]   higher KV motor 36,000 KV is pulling more RPM with the propeller on but watch this this this is where things get kind of sort of weird but super

[00:54:04]   interesting it's when we pull the propellers off and we spin these things as if it's a KV test again we can't spin them up to 100% the 8bit esc's have a hard limit as to how high

[00:54:20]   of an RPM they can spin a motor and we are now beyond that limit but we don't fly these things without propellers on and once you put the propeller on as we just saw it drags the

[00:54:36]   RPM down to the point where it gives us actual numbers right we didn't get the exact same number between those two so we got good data and

[00:54:51]   so in order to get unloaded RPM data we just need to not spin it up at 100% we're going to spin it up to 50% we're going to do the same thing and then Kevin's magical Spreadsheet will

[00:55:07]   make the conversion for us still on four volts powering up the es the AO we're going to come back here understand the risks and now Motors one and three are newbie drone ready motor

[00:55:24]   one oops nope I lied well it's not reporting back RPM hold on disconnect and reconnect understand the risks there we go now it's good and I don't I don't have to hold it for this because there's

[00:55:40]   no propellers on it so I can just put it here because I need to get this slider into the middle so that can hang there so here's what I need to do with this slider I need to use the up

[00:55:52]   and down arrows to get it exactly to we're shooting for for 1500 right so I need to get it close and then 1500 and 56,000 we're just going to say 56,000 RPM ready so that's the one not ready

[00:56:07]   56,000 and we're going to do it on the other motor and 56,000 good all right so now we come in here and 50% no prop 56,000 55 6 0 ready and now we're going to test the HappyModel motor watch this

[00:56:31]   watch this watch this remember that number 56,000 this is the HappyModel motor 7,000 KV higher come on 60,000 it's not that much higher right 60,000

[00:56:57]   yesterday they were a little bit closer than that I think so 60,000 not as big of a gap as you would think right I believe what's going on is that and we see this when we fly

[00:57:19]   these two Motors and I'm actually going to I I have a set of these newbie drill 0702 29,000 that I've switched the I've switched the plugs over to the Newbie drone Motors are less

[00:57:35]   efficient I I and I I think that's what we're going to start to figure out here but let's keep going let's keep testing Motors next thing I want to do is confirm that

[00:57:46]   the that the 36 thou I have another rig with the 36,000 KV Motors I want to confirm that one AI is not going to turn different numbers than another

[00:58:02]   so we're going to test this guy and we can actually test all four Motors on this one already has the GemFan by blades on it so we're good let me just check one last thing on the on the rig that I

[00:58:18]   just flew I need to make sure that I'm spinning the propellers in the correct direction if you if you spin the propellers the wrong way they I think they're more draggy

[00:58:32]   it might not make a difference but I I I don't want to find out the hard way so let me plug this back in real quick and just make sure that it set up props in because that's how the props were on

[00:58:43]   it I'm pretty sure I I confirmed this yesterday but let's just make sure here and here and Motors okay Power It Up with four volts understand the risks and we're

[00:59:06]   just going to spin these motors up a little bit and we've got props in props in props in props in perfect okay cool just wanted to check all right

[00:59:20]   unplug and unplug all right cool so first little bit of data there now we're going to confirm that a different rig a different aiio it's also a 2g4 but still it's a 2g4 with more or less abuse

[00:59:38]   done to it let's see how these numbers kind of line up and you will we will see Motors that are that are like hot with the props on also with the props off that's

[00:59:55]   something that I have noticed in spinning Motors up like this in the past but it's usually like just one there'll just be like one that's kind of spins up

[01:00:07]   higher although so far each of those Motors were pretty damn close to one another so let me check that everything is spinning the right direction first so Props in props in props in

[01:00:26]   and props in Great and the propellers are correct for that okay cool prop on test 0702 36,000 to compare to what we just did ready 64,000 64,000 64,000 64 65,000 not too bad pretty

[01:00:57]   consistent 64,000 KV and let's unplug I think those are the same numbers that we got in the other one let's double check yep there it is all right cool good good good good good good so that

[01:01:16]   means that you guys can kind of get in on this if you can if you can make sure that your uh voltage so I'm going to put a little note here

[01:01:36]   voltage at 3.8 volt that that's what 3.8 is what I'm seeing I'll show you again in a second let me pull the props off well actually I should put it here 3.8

[01:02:00]   volts take it out so I want to put it in here RPM at 100% oh I guess I I guess I also need to look at oh it will be hard for you guys to do this 1210

[01:02:23]   prop Dash 3.8 volts I got to add that in there it has to be there Dash 3.8 volts and then with with no prop on it I bet you it's going to be four volts so I'm just G

[01:02:40]   to add that okay all right cool so propellers now need to come off man I'm going to I'm going to pull a ton of propellers off today so now that you guys have a time to like

[01:03:01]   see me do this and kind of think through this what am I missing what am I missing here wny am I only realizing this now is it I I think I'm only realizing that we can do this now

[01:03:18]   because the cuz I never realized that we could just spin 50% RPM and I never I also never realized that the the rated KV numbers on these motors were so potentially so

[01:03:35]   off I don't really need to remove all four of these propellers this was kind of a this is a bit obsessive but whatever let me get caught up on chat Zack says how dod he just finished

[01:03:48]   my 75mm 2S hd0 build 803 19,000 sub 250 Motors 2 and 1/2 minute run time outside most fun moop I've ever built thus far it's a smooth rocket 08039 I'm super curious about those

[01:04:02]   Motors actually two and a half minutes outside 75 mil excuse me 2S hd0 interesting are you running those Motors at Full Tilt to I would expect 3 minutes are you like really it's so hard it cuz if

[01:04:22]   you're cruising faster than me it's really hard to tell which what batteries is that a 300 MH battery or 450 MH battery hopefully that's a 300 MH battery Walter

[01:04:35]   says I think you have too much too many unknown variables there are a lot of unknown variables but I think we're still going to get some half decent data here factories work with

[01:04:43]   companies and get their hands on so run a badge it's like the weiring be 205 some minus there's there's a lot this is not a perfect test but this is a test nonetheless I think we're going to get

[01:04:58]   some interesting data on this Kevin sum says div SL zero errors will go away as you fill in the sheet very cool Kevin Su says I think it's actually unclean power coming out of that power

[01:05:08]   supply at low voltages however verif oscilloscope Kevin also says don't forget to fill in voltage oh did you add a column for voltage oh look at you go [@$#%] voltage at 100% 1210 prop okay so

[01:05:27]   oh I think think Kevin already did that let's change this one to take this out I'm G to test the voltage in a second here but I think it's going to be even across the board

[01:05:50]   3.8 it's this will be oops [@$#%] copy paste there we go thank you dude I see what you did here I see what you did here voltage is 50% no prop RPM at 100% 1210 16 we'll we'll check

[01:06:18]   the voltage there okay cool cool co all right unloaded RPM number is coming up and for this I can just let it sit on the desk okay all right that's fine I can hang out there connect

[01:06:48]   and we go Motors understand the risks here we go so we want to go to 50% get it close and then use the up and down arrows to get it exactly right 60,000 voltage is sagging down

[01:07:09]   to 398 which is basically fine 60,000 that's what we want to see we're just getting consistent numbers right now 60,000 again great we're checking the consistency I should say 60,000 a little bit high

[01:07:23]   on that one but still it was I was seeing 16,000 60,000 sorry and then 60 perfect good better consistency than I thought to be really honest so we're good and that also confirms that the voltage is

[01:07:41]   sitting right at four volts so we can no no no no no wait wa wait no wrong column wrong column scroll over to the left 4.0 not 40 4.0 we can take this copy it and drag it down all right

[01:08:03]   good deal so 60,000 that's what we just retested and they pretty much all came up right around 60 I am wildly rounding these numbers off because I know that this is not a perfect test but I I we

[01:08:17]   going to be all right we're not looking for exact we're looking for like big big differences between the two so estimated KV oh look at that so here's what's super

[01:08:38]   interesting right estimated KV at 50% Throttle No prop this is a 29,000 KV newbie drone motor 29 29,000 KV 0702 the estimated KV is coming in at 28,000 that looks about right look at this [@$#%]

[01:08:57]   36,000 KV HappyModel motor the estimated KV is only coming in at 30,000 but it's doing a lot more work where's the 12 so then all right so one of the things so all right let me grab the

[01:09:25]   calculator real quick so once the prop is on we don't we don't need the estimated KV the the prop on number is just to determine the difference so basically what I what

[01:09:43]   I'm what I'm looking at right is so for the Newbie drone motor 60,000 just call it 60 divided by so that's with the prop on divided by 56 equals let me do that the other way

[01:09:59]   around let me do the small number divided by the big number so basically 56 / 60 equals 93 right so .93 is the Newbie drone differential between prop on and prop

[01:10:17]   off and then if we go over to the HappyModel so point I'm just going type it into chat real quick 093 if we go over to the the HappyModel it should be different 60 ided

[01:10:32]   64 wow 093 it's pretty close 9375 hold on maybe the maybe it'll be closer than I thought I'll be damned hold on 56 / 60 equal 933 so 933 versus

[01:11:02]   937 all right so we are seeing a difference so now let's get another motor in there let's get another couple Motors in there to beef that up and to give us more numbers on here I

[01:11:19]   was hoping that we would see a bigger gap between those two but maybe maybe not hang on a second just getting these props put back on this rig because we are going to fly you should have already

[01:11:34]   flown wait no it's early you should be you should have a plan to fly your six batteries for today my friends I'm going to get a few in before the end of this live stream probably with this

[01:11:44]   36,000 KV rig because I'm tearing apart a lot of the other rigs to do some of this testing here okay so what's next we we've got fire up these 40,000 let's try these

[01:12:07]   40,000 oh wait no no no no no here we go here we go here we go this will be super interesting here's some 802s we'll go super low KV here's some HappyModel 802 19000s here they here they are on the

[01:12:23]   sheet let's just add hm all right 802 19,000 hopefully this will make a big difference this is actually a oh by the way get FPV has a whole bunch of 2G fours in stock go snag

[01:12:47]   some ah [@$#%] I can't test this it has pH 2.0 but I can certainly take a motor off of here let me do that I can pop a motor off of here and we'll put it

[01:13:04]   onto this guy oh what we can do real quick let's take a look at the BetaFPV Motors on the on the air on the air 65 with the wrecked VTX from me putting into the water this will also confirm

[01:13:19]   that other other aios can turn the same sort of RPM all right so plugging this in oh these are Tri blades on here though I got to switch these props out all right hold up hold

[01:13:37]   on Kila zebra says Kil zebra says TTI FPV just an idea for testing Motors in Flight you could use the audio frequency coming from the motors to figure out how fast they're

[01:13:56]   spinning very true 60,000 RPM equals 1 khz Audio Pitch that's super interesting well in Flight BetaFlight will give us the so this is the other thing if if we beef

[01:14:13]   this up that we can we can test even more BetaFlight in the postflight statistics will tell us maximum the maximum rpm the problem with that is that when we're flying these things they have to be on a

[01:14:29]   battery so a freshly we would have to like pull a battery off the charger plug it in immediately go full throttle and where can I do that I can't really do that across the room in the basement

[01:14:40]   here so then I have to go upstairs and it's like if I let it realistically You' have to do it outside and so the the amount of you think there's a lot of you think there's a lot of variables

[01:14:53]   with what we're doing right now that would be like next level tons of variables so I don't know if we can really do that these are let's get some numbers on beta

[01:15:05]   FPV 0702 SE 27,000 KV Motors these are the ones with the bearings I think somebody knows the SE Motors are they the ones with the with the bearings or no so this is props off

[01:15:29]   first props off fire up BetaFlight connect batter's plugged in it's powered on should be good here nope on should have p power it does it's not spinning the motors though

[01:16:00]   that's weird hold on what oops nope it's not what we want understand the risks huh that's weird why is it not What's your deal little guy it was it was flying fine but the

[01:16:23]   the VTX just wasn't working I'm not getting any motor beeps oh I desoldered the motors I desoldered the motors I forgot that I did that okay not checking those and they don't have plugs on them

[01:16:46]   why did I I I guess I desoldered the motors because I knew that the AIO was blown up oh well all right we're not testing we're not testing BetaFPV Motors God that's annoying

[01:16:56]    I am going to get another air AO though and get that rig back up in the air can't test this it's pH 2.0 that was a fail okay let's test 32,000 KV Motors all right so I'm going

[01:17:16]   to go back to this little test rig and start to pull stuff apart Kevin Sumer says do you want a column for the prop on differ yes please yes please yes please that would be amazing Kevin thank

[01:17:28]   you thank you thank you double zpv says you said volunteering is a great way to meet cool people so after stalking everybody's castle crash videos I took leave of Faith yesterday sign

[01:17:36]   myself up nice hope to meet you there Ripon packs bro man I'm super looking forward to it Kevin says Pro tip page up page down to jump the throttle by 10% not anymore they took that out for a

[01:17:53]   while it was hold shift and arrow up and arrow down and then it was page up and page down and now that doesn't work anymore which is super annoying cuz that was really handy but I'll try it again

[01:18:04]   in a minute they they've changed the motors tab if you hit any key on the bottom of your keyboard it instantly deactivates the motors it's for safety which is great so if you hit shift

[01:18:17]   control option command or space bar in that Motors tab it automatically shuts the motors off which is a really nice little kind kind of safety thing that they're doing now

[01:18:28]    so that's kind of cool I have other hold on to speed this up I have other built rigs that I should be able to just spin up yeah here we go here we

[01:18:45]   go 32,000 KV Motors on here this has 36s we've already confirmed that the 36s are pretty pretty accurate what's interesting though this is a different AO let's keep

[01:19:03]   the myth busting going this is a Mobula 6 2024 AIO with 36,000 KV Motors on it let's see if this will turn the same RPM as a 2g4 AIO it should but stranger things have happened right

[01:19:26]   let's take a look here got this got this I'm not going to bother pulling these propellers off I'm just going to test this props on and I'm not really going to learn

[01:19:43]   anything here but this will potentially I don't know come on BetaFlight come on BetaFlight what are you doing work all right let's try this sometimes beta flick gets all Angry come

[01:20:29]   on come on come on come on come on come on come on on there we go all right so let's just see real quick this should turn I think it was

[01:20:45]   60,000 this is a 2g4 version twoo whoa yep 64 good 6 4 64 64 cool pretty way more consistent than I thought so nothing wrong with the you're getting full power with the 2g4 and again that's a that

[01:21:11]   that is static air that that is asking this thing to do more work than it ever needs to do in the actual when it's actually flying so what do we got here this rig has ah

[01:21:25]   awesome this rig has 28,500 on it perfect that'll be great to test this one has 32,000 KB Motors on it great and then this one here has [@$#%] this one has 40,000 oh but

[01:21:40]   I can I can use this guy for that all right sweet we don't have to you don't have to sit here and watch me unplugging motor plugs and unscrewing screws for a minute I can use a couple

[01:21:53]   of these rigs that are already built although I do need to pull the propellers off this one so this is the rig with 28,500 KV Motors I just need to pull the props and then we'll see what these turn in

[01:22:16]   at all right this fella is almost ready come on I don't need to test all four I can just test Motors one two and three that's fine okay Motors number one two and three do not have propellers on

[01:22:40]   them we can all we can also test props we can use this to spin props up to see how draggy they are that's actually that would be really handy to know I'm going to spin so I I still have

[01:23:06]   one HQ YOLO prop on here I'm going to spin this up and we'll compare it to the to the to the 1210 by blades oh that could be because like the I don't know the the pitch numbers sometimes don't

[01:23:20]   make a lot of sense on these and that's kind of cool we're going to try that but first let's get props off numbers so these are what did I say 28,500 should be at

[01:23:43]   least let's see what one oh no no no no no 50% throttle 50% throttle oh no it's page up and page down still does work awesome 50,000 motor 2 Oh Boy motor 2 doesn't want to spin what's happening motor

[01:24:05]   two What's your deal what motor two what's your damage it's all it's like bound up what's what's happening there little friend there we go he's fine what did I say 50,000 motor one

[01:24:26]   motor two be cool 52,000 let's recheck motor 1 50,000 call it 51,000 so 51 52 47 Jesus no no there it's up to 50 51 52 50 this is the one with the prop on I'm not going to spin it up yet 51 52 50

[01:24:53]   so so 51 is right in the middle so 51,000 KV unplug everything from 28,500 51,000 KV we're going to insert one row below oh [@$#%] didn't mean to do that insert one

[01:25:25]   below hm 0702 28,000 28.5k no prop 50,000 all right no no no what it's 51 we had 50 51 52 so we're going to round off to 51 all right 4.0 volts 25,000 so look at that 28,000 so

[01:26:01]   the the difference is much tighter here 28 look at this guys look at this see now we're now we're starting to really see weird [@$#%] happening let me just double check that

[01:26:17]   these are 28,500 28,500 285 these are the wee bed Motors 28 5 yep 285 all right cool so look at this look at this man 29,000 KV 28,500 KV look at the difference in RPM look at the difference

[01:26:38]   in the estimated KV isn't that wild now watch this now now we're going to put propellers on and it's going to get truly weird right check this [@$#%] out so this is why

[01:26:54]   is this set up props out that's weird props out is here props out here I guess it doesn't matter these are this is a drift car chasing rig so Props in props out doesn't really

[01:27:12]   matter I'm not really doing Dives or anything with it okay so now we've got three 1210 by blades and one of these YOLO HQ Tri blades just for just out of

[01:27:33]   curiosity but watch this I think we might see something really interesting here ready I think these are going to turn a higher RPM with the props on I think they're going to be able to do more work but

[01:27:51]   let's find out together Motors all right ready motor one and now we're going to go up to 100% because we're not worried about that RPM limit 60,000 60,000 60,000 and now watch this motor 4

[01:28:13]   with the tri blid let's see what happens here wow 60,000 I'll be damned okay and so HappyModel 07 102 RPM at 100% 60,000 same propon RPM as the Newbie drone motor so

[01:28:42]   now this is where things get kind of confusing but kind of interesting too what I think is going on is that the Newbie and so when we run these motors when when I fly this rig

[01:29:01]   with these HappyModel 28,500 I get over 3 minutes of runtime when I fly those newbie drone Motors I'm going to get around two and a half minutes of

[01:29:14]   runtime and I think we're we're seeing the tale of what's going on here I believe new drone is winding this you could look at it either way you could I guess we should look at it the

[01:29:30]   other way I guess we should look at it as HappyModel is winding their Motors to be a lower C they can afford to wind their Motors at a lower actual KV because the motor is optimized and it

[01:29:46]   pushes the propeller harder because it has more potentially more copper in the Stater or stronger magnets or better flux ring or a tighter air gap but these two Motors are a pretty different actual

[01:30:02]   measured KV but then with a propeller on they they're they're turning the same RPM so at Full Throttle these two Motors are going to perform very similar but they're going about it in a drastically

[01:30:18]   different way the the the Newbie drone motor is wound in a way that with the propeller off it's turning I mean it's turning a KV with the propeller off that's closer to what its actual rated

[01:30:30]   number is which is kind of interesting but this I believe this starts to kind of tell the tale of efficiency in these motors and I it's looking like these HappyModel Motors

[01:30:46]   are are wound in a way that they're actually not putting the they're not turning the same KV as the marking but then they make really really good power so let's keep going is that

[01:30:59]   have I lost absolutely everyone I'm kind of walking through this myself too right I didn't do any of this testing because I figured we could kind of do it together and then in

[01:31:12]   the chat as I make mistakes you guys can hopefully correct me Andor we can all sort of learn together so hold on Zack says regarding the O 83 motor it's the same as yours 2S walks

[01:31:26]   snail 03s are a tad lighter than the 102s would be interesting to hear how they compare I'm super interested in those Motors Walter says drag extra Factor but a good one he

[01:31:36]   also says they learned a lot propellers Corsair warboard it's interesting pic free H says in my testing for RPM per group I used postflight OSD for Max RPM and they give a two second Full Throttle

[01:31:47]   punch straight up Outdoors would that be possibly more accurate than holding the rig I don't think so I think using the the the power supply here and handholding the rig is the way to go

[01:32:01]   rather than putting a battery on it and then Walter says you're not lost good way all right cool okay so I am very surprised that the HQ triblade was able to turn to the

[01:32:19]   same RPM that's kind of crazy I don't know what to I don't know what to think about that if I'm honest I thought for sure because we went from a two blade to a three blade

[01:32:36]    I thought for sure that the HQ prop would turn a lower RPM but HQ does not tell us what the pitch is so maybe on their ultra light triblade maybe it's a 10 pitch you know

[01:32:52]   the the pitch of the propeller is a measure of how much distance it will travel in like a fluid basically with one full rotation so if they're the same pitch

[01:33:09]   they if if the tri blade is a lower pitch man it certainly doesn't look like it they they certainly appear to have the same blade angle but there's more that goes into pitch than blade angle

[01:33:20]   the the shape of the blade has a lot to do with it as well I would not have guessed that that's I'm a little bit confused by that if I'm honest but that's okay we can be

[01:33:37]   confused props out props in I'm going to switch this rig to props in actually real quick since I have these off I might as well props in seems to be lately kind of the way to go God forbid

[01:33:51]   I ever tried drop elevation with this o oh oh oh is this is the Hub on this guy starting to crack oh it is indeed or is that in the material nope the hugle The Hub on this

[01:34:12]   HQ ultral light prop has a big old crack in it look at that interesting I've never seen that before I'm GNA keep an eye on that I don't love that it still seems

[01:34:33]   to go onto the motor shaft fine though so maybe it's okay but there's a visible crack top to bottom oh my God this one too what this one too oh my God they all have they all have cracks in the hub

[01:34:55]   that's weird these are custom dyed so I guess you could maybe make the argument that during the dying process over at tiny whoop it's cracking the Hub a little bit but

[01:35:08]   they they they're fitting fine on the motor shaft so I think they're okay that's odd but it'll be all right hold on one second let me just flip the flip this from props in to props

[01:35:22]   out super quick all right and Motors props in save and reboot okay connect murders motor Direction understand the risks wizard spin motor one out change it to

[01:35:51]   in oh Christ these are not reversing what two all right I have to I have to do this in ESC configurator hang on this will be but a second connect read settings all four of them

[01:36:16]   are go in the wrong direction so we're going to go normal to reversed reversed to normal reversed to normal reversed to normal right settings okay and

[01:36:32]   now boy is that not time consuming now if I spin them up a little bit one is props in two is props in four is props in three is props in we're good okay I would have forgotten to do

[01:36:52]   that and then I would take this to the drift car place this Thursday and be pissed cuz it wouldn't be flyable all right so we've tested 28,500 let's move

[01:37:05]   to 32,000 KV Motors and I'm just going to pull two of these props off I I don't need to test so many okay I'm not going to pull that one off because it won't come

[01:37:19]   off this one's coming off already so we're going to test test motor 2 and maybe motor 3 see if this prop will come off without a massive fight there we go cool test Motors 2 and

[01:37:35]   three these are HappyModel 0702 30,000 here we go and so we're going to do props off first Motors two and three all right Zoom you guys in a little bit oops [@$#%] Motors understand the risk all right

[01:38:06]   motor two nope nope nope nope I only want 50% there you got to see the limit 85,000 RPM is the limit, 1500 56,000 and 56,000 great just of curiosity these are the ones with the props on

[01:38:28]   64,000 64,000 interesting I forget 56,000 all right 56 so okay unplug and unplug all right 56 so this is HappyModel 702 32,000 nope here it is hm and it was 56,000

[01:39:06]   right that's the same as these newbie drones interesting I don't trust myself I'm going to double check it one more time hold on pretty sure it was 56,000 I'm going to do this and then I'll just

[01:39:22]   smash the the propeller on be fine won't waste much time here pretty sure it was 56 but it does take long to check it Motors this motor 2 yep

[01:39:38]   56 three 56 yep okay and now I'm just going to smash propellers onto these two they are props out props out and so Props out here put in a byblade 1210

[01:40:07]   on there's one and props out we need this one all right let's see see what they do with 1210 on them motor two full power oops click here motor two 64,000 motor 3 64,000 this is where it starts to get

[01:40:36]   weird 64 oh oh oh this is not necessarily where it starts to get weird this is just where we start to see the difference between loaded and

[01:40:48]   unloaded 32,000 KV 702 36,000 KV 702 look at that look at that but when you fly these two Motors they absolutely perform different unquestionably there is more power on

[01:41:10]   the 36,000 KV motor because when you fly it for real it's not tied down it starts hurdling through the sky and it gets incoming air which makes the motor's job easier and lets the motor

[01:41:31]   turn to a higher to a higher RPM Walter says if the point of propeller goes through the the speed of sound it'll give resonation we're we're not we're not close to the

[01:41:49]   speed of sound yet so we're good there what I would o what we can also check here is 24K versus 96k but let's let's just keep going let's let's test as many different

[01:42:10]   Motors as we can and then we'll start screwing around with that stuff I wonder I wonder if on the 36000 KV motor if we go up to 96k I wonder if we'll see like a

[01:42:28]   noticeable increase I I wonder if that'll be able to push the prop significantly harder but again we'll we'll test that probably on another stream right now let's get a big chunk of

[01:42:46]   data here and then we'll the main thing that I'm trying to figure out here is HappyModel Motors versus every other motor brand what's kind of happening why is Happy

[01:43:04]   model able to produce Motors that are so much more powerful and so much more efficient and we're not going to find out how here but we're going to like kind of confirm that that's

[01:43:15]   actually happening right because up until this point it's just when when I fly them I feel more power this is cool to put some like some actual data on that so this guy is

[01:43:31]   good to go we're done testing with him 40,000 KV Motors this should be interesting props on totally different AIO too now we're going over to a BetaFPV AIO

[01:43:53]   the cross style props on first 40,000 million quadrillion billion RPM KV rather well in a second it'll be well no I bet you it spins up to 64,000 which is not the limit there is

[01:44:10]   no hard limit down at 64,000 KV let's see 64,000 64,000 I did see 64,900 though whoa oh boy motor 3 reset the ESC 64,000 touching into 65 64 65,000 so they are turning a

[01:44:34]   little bit more RPM but not much and now let's take a propeller or two off wait hold on it only barely touched 65,000 so so I'm going to put it in as 64,000 I'll put 500 it was turning a

[01:45:01]   little bit higher than the than the 36 case and I want to add hm to this okay 702 40,000 yep all right so now let me pull a couple of propellers off here motor one I'm just going to pull that one

[01:45:33]   prop off kind of running out of time here just pulling one prop off I've been really surprised at how dialed in these motors have been ready so motor one prop is off go up to

[01:45:51]   50% and we're getting 70,000 that's the highest that we've seen 70,000 and now let's take a look so here wow that's a big jumpthat's a that is a massive jump look at

[01:46:15]   that from 36,000 KV to 40,000 KV we went from 60,000 RPM to 70,000 RPM but look the the the estimated KV is still lagging behind quite a bit right 36 down to 30 40 down to

[01:46:38]   35 interesting let's put this prop back on and we're done with this rig could be something with the ESC technically speaking maybe this ESC is pushing harder somehow I doubt it but

[01:46:59]   you never know we'll we'll dive into stuff in the future okay so what's up next now we got to start pulling Motors all right I'm going to pull a bunch of Motors off this

[01:47:16]   chat what what do you guys think what do you think about how this has gone so far and or where this is going kind of interesting right seeing like one motor

[01:47:38]   that I'm really surprised at how low the the estimated KV numbers are on the HappyModel Motors and I'm shocked how dialed in the Newbie drone motor

[01:47:57]   is right now we're going to try another newbie drone motor and a VCI motor so here we got 30,000 I think wait no I don't have another newbie Dr motor I was really banking on testing those BetaFPV Motors

[01:48:22]   I really wanted to test those but oh oh actually Joshua just sent me a box of goodies maybe there's a BetaFPV motor in that box hold on we're going to test four different

[01:48:34]   Motors now four different Motors one of them is going to be a VCI 0702 29,000 I'm going to bolt this guy on here and I'm just going to start testing no I should test two at a

[01:48:57]   time because I've seen I've put like four Motors onto one of these and one motor is like drastically higher or drastically lower come on come on come on come on get in there there we

[01:49:18]   go okay all right so we're going to test two VCI 0702 and then we're going to test two something else maybe these are all on Blue J with 48k pwm for the record

[01:49:52]   Chris Rosser put out an excellent video on with some PW with some blue J ESC settings a couple days ago that's really good but what I want you to remember is that 96 96k pwm frequency there are no

[01:50:10]   free lunches you're going to lose engine motor breaking it doesn't look like you lose a lot of motor breing but motor breaking is super important 702 29,000 so there the same Motors in here

[01:50:24]    that I have here we go V VCI 703 23,500 we're going to test the hell out of those beta FV CO3 camera CO3 camera brushless motors here we go yes oh thank you Joshua for sending

[01:50:49]   these and then 1102 22,000 probably not to test those but all right great great great great great great VCI motor Showdown 702 versus 703 here we

[01:51:04]   go I haven't flown these 703s yet these could be super interesting I'm actually really interested in the in the RC and power 703s too all right

[01:51:23]   look how VCI packages their Motors they put them in little like vacuum sealed baggies with a little tear part on them kind of cool okay 703 man these look tall you can see the proportions are are quite

[01:51:46]   different on these 703s okay so I need to pull these other two motor off and swap these on what are you guys talking about in chat notice I see trash magic that's a

[01:52:08]    now famous description of HappyModel motors from quad 66 it's so good quad 66 tested these newbie drone Motors the BetaFPV Motors and the HappyModel Motors a few months ago

[01:52:28]   and basically at the end of the testing he's like the happy models are more powerful and more efficient but they sound like trash but they're magic they're they're bushings

[01:52:42]   they're not bearings and they they can get a little rattly but it doesn't matter like they sound like trash but they are a magic motor they make more power and they're more efficient and

[01:52:53]   that's weird all right last newbie drone 29,000 KV motor coming off here man I wish I had a set of beta fpv7 02s with motor plugs on them that I could test that is a shame at some point I

[01:53:19]   will get my hands on them or I will break down and direct solder one of those that I have actually no what I'll get a replacement air 65 AIO I'll put that thing back together and

[01:53:34]   then I'll be able to test those Motors but then they'll be direct soldered which is kind of not a fair fight oh man we could use this to check direct soldered versus plugs although I mean

[01:53:49]   there's no chance that plugs are going to flow electricity better than direct soldered we don't do the I don't do the direct soldered thing because it's not serviceable and it's a pain in the ass

[01:54:00]    I'm almost certain that there's at least a little bit of efficiency to be had by going to direct soldered but in my opinion it's not worth it especially with how much testing I

[01:54:15]   personally do for you guys if you're not going to do a lot of testing sure that's a bit different but for me case in point look what I'm doing right now what I mean

[01:54:30]   like this testing that I'm doing right now I would still be on the first set of Motors if if I had to direct solder all these so right now is a is a perfect example of why motor plugs for

[01:54:44]   tiny whoops I think are a necessary evil all right there we go four VCI Motors plugged in and ready to rip two 72s two 703s man look at the I don't know if you guys

[01:55:08]   will be able to see it but there is a huge difference in height between these two Motors hold on you could totally see it 703 on the left 702 on the right look at that

[01:55:30]   difference man that's cool 703 is a really interesting Stater size it's comparable to 802 but different at the same time I don't have 7 any 703s on the

[01:55:53]   sheets let's put it here VCI 0703 what's the KV again 23,500 23,000 23.5 okay what nope not comma 0703 23.5k 40 okay all right so we're going to test this VCI here and then we're also going

[01:56:29]   to test VCI 072 what are they I got to look again the 0702 is 29,000 29,000 so let's insert below and it's going to be VCI 07 72 29k is that what I just said 29k Jesus yep 29 all right let's take a look

[01:57:03]   any any guesses I can I'll give you a second to think about that I can tell you exactly what I think is going to happen and I if you've been paying attention you probably know what's about to

[01:57:20]   happen all right props off numbers 07 02s are well I mean this this will be super obvious the the the KV is so different between these motors this will be blindingly obvious which motor is

[01:57:34]   which well it should be at least props off 50% let's see 56,000 wait wait hold on yep 56,000 5657 5 556 wow this is way closer than I thought 46 there we go never

[01:58:01]   mind 46 46 47 so 46 versus 56 46 versus 56 hold on now 46 and 56 look at that same as the Newbie drone 29k 5600 starting to see a trend my friends was it 46

[01:58:39]   right for the 23,500 KV look dead on the money dead on the money for 0 703 and then oh when I'm inserting a line it's deleting the it's deleting the the formula I

[01:58:58]   think but look it's the same 56 29,000 KV 56 I bet you when we test the BetaFPV Motors the exact same thing happens I've got to get these props spinning in the whatever I'm just going to put

[01:59:20]   whatever propellers on no I'll set it up for props in props in props in Kevin how do I insert lines without it deleting the the formula all right props are on they

[01:59:44]   might fly off props in props in props in props in okay thank you Kevin okay 1210 gem fans are now on here plugging USB back in plugging power supply back

[02:00:08]   in all right first thing I need to do is get these spinning the right direction motor Direction wizard close actually I'm going to tell this props in save and reboot

[02:00:22]   just because I want this thing to be props in moving forward well not modes Motors got the M right motor Direction I understand the risks wizard starting spin great

[02:00:32]   motor number one is correct two is incorrect hopefully it reverses yes three is wrong that means four is going to be right yep props in props in props in props in start motors do this just to

[02:00:51]   double check in in in in good we want to make sure we're spinning the propeller in the correct direction during these tests okay here we go m one full throttle now 60,000 motor two

[02:01:11]   60,000 SE seen a trend whoa 64 6460 and 64 okay hold up 60 and 64 that is actually super [@$#%] interesting 60 and then 64 all rightthat is really cool that is really really really cool

[02:01:54]   so we talk about how you can keep moving the KV up higher and higher and higher and higher and the motor will make slightly more power but then you can you can also make

[02:02:11]   the stator bigger and a bigger stator is going to have more torque to push the propeller harder and so we in this situ this weird not weird but 702's when you hold the rig in your

[02:02:29]   hands and it has to take all this static air and then move it right it's not moving through the air this is a static test like what we get with a Thrust stand 702 Motors really run out of steam

[02:02:42]   we can see this we can see this right here so we've got 702 so this is prop on RPM here and now look what happen 702 36,000 KV 702 32,000 KV no extra RPM in a static loaded

[02:03:06]   environment look at this [@$#%] 23,000 we just tested an 0703 much bigger stator but 23,500 KV motor low ass KV just turned the same RP M as a 702 36,000 KV motor and this is only on a

[02:03:28]   1210 propeller this is not on like a big ass 1.6 inch prop that is I didn't think it would be that drastic the pro so then you would think like oh well I just want to run this

[02:03:41]   0703 23 no no no no this is a much heavier motor right and again this is a loaded test a loaded thrust stand this is not a good indication of what actually happens in the air in the

[02:03:56]   air this motor I'll show you I'll show you yeah here this is great we're going to we're going to fly a battery real quick we're going to fly a real quick battery on the rig

[02:04:14]   that's got 36,000 KV Motors and then we're going to look look at the postflight stats let me make sure that the postflight stats are on for RPM o this is going to be good this

[02:04:29]   is going to be good we can do this real quick and get a little bit of flying in while we're at it because I did put six batteries in the title make sure you've flown your six batteries today friends

[02:04:39]   don't not fly it's like 15 minutes of your life do it you're going to get better it's going to be worth it what am I looking for OSD post flate stats maximum rpm

[02:04:53]   GeForce maximum ESC RPM maximum great perfect watch this and now this is not on a power supply this is just with a battery which G which is going to Sag quite a bit

[02:05:09]   but Watch What Happens I I'm super curious what the what the RPM is going to be I'm going to fly it straight UPS stairs and do a full throttle blast as early as I possibly can in this

[02:05:29]   battery ready and then we're going to take a look so look look how much the battery has sagged already it's already sag sagging down to 4.27 I'm going to limp it look even at

[02:05:44]   at at at just hover it sags down to 408 so we're not going to get that full Voltage but I don't think it's going to match matter ready that was a pretty good

[02:05:59]   one ready what's the number going to be 56,000 there you go my friends 56,000 because it's in the air and there's incoming moving air into the propellers so the the motor have to do a lot less work

[02:06:23]   right because they've got 10 20 30 40 m hour of incoming air this is why thrust stand testing of these 0702 motors doesn't really work because we've optimized these

[02:06:39]   motors so much that they they come alive in the real world versus on the thrust stand wow that's a big difference and that's pulling RPM data from the same thing

[02:06:57]   right we're looking at BIR directional dshot RPM data which is not the most accurate thing in the world but it's pretty damn accurate man these 36,000 KV Motors RIP just bring this battery down oh god

[02:07:16]   oh boy oh boy no no no what what I think I'm stuck like under a plastic bag of some sort I Hear My Savior My Savior thank you teddy going crazy Teddy going crazy Teddy spaghetti

[02:07:49]   time oh he hit me he got me I love it where's that little dog there he is little buddy boy smack me out of the air I see it I see it 56,000 KVis that 10,000 more

[02:08:11]   KV flyo six batteries today friends you can thank me in a couple of months when you're an absolute tiny whooping Ninja railing through the house power looping Matty flipping doing all the

[02:08:26]   things ah I tried to get like oh super weird with it oh God oh God that's coming my way look at the run time man two and a half minutes we were railing upstairs we were absolutely blasting

[02:08:49]   upstairs and we're still at like three point I'm looking at the battery voltage instead of where I'm going we're still hovering at 3.58 3.57 these HappyModel Motors are

[02:09:05]   magic trash magic as quad 66 puts it look there it is there's the super like whipped out Cool Whip ah oh God nope that battery is probably in a good spot right

[02:09:28]   great 56,00050,000 on a dead battery so there you go that's important to understand all right that once they're up in the air so here what's what's the what's the difference up in

[02:09:48]   the air 56,000 12,000 so this is the this is the loaded me holding the quad wait wa wait F whoa It's lower no no no wow I thought it was higher sorry 56 versus

[02:10:09]   64 okay so it's pulling the battery down hard if we had a battery that could maintain four volt damn it I knew I should have done 3.8 volts on the power supply [@$#%] the battery is this battery

[02:10:24]   in flight at Full Throttle is probably sagging all the way down to 3.6 if somebody can is somebody willing to rewind and take a look when I was absolutely like railing across the room

[02:10:35]   how low this battery was sagging damn 56 I I thought it was 40 I I was I thought it was 46,000 not 64,000 [@$#%] I should have put the power supply 3.8 e though even at 3.8 though I think

[02:10:54]   this battery is sagging way down below 3.8 I think it's sagging down close to like 36 35 at Full Throttle especially on these mega power motors [@$#%] okay that's fine are we

[02:11:11]   good with the with these VCI Motors I think we are I think we're good with these VC let's get them off of here we can do couple more Motors herethese 0 703s pushed this propeller

[02:11:31]   hard that is that is wild I I didn't think it would be it would make that much of a difference it makes sense it really does so what that also tells us is that even at 30 even at 29,000 KV

[02:11:51]   the the 702's like 29,000 KV is a really high is a really high KV for a 702 but then once it's flying through the air it's really really really

[02:12:07]   helps Black Horse says static RPM will be the highest possible the faster you go through the air the less RPM there is that's not my understanding of it as the faster you go through the air

[02:12:25]   the less work the motor's going to have to do so it's going to be able to push hard much higher notice says saw 3.6 while ripping upstairs when you parked and solve 56,000

[02:12:39]   KV I wonder if there's math that that can be done to go from to convert 3 point to convert 56 somebody will know how to do this somebody knows math in chat so if we're getting 56,000 KV on

[02:12:55]   3.6 volts what would that not KV 56,000 RPM on 3.6 volts what RPM would we get on 4 volts on 3.8 volts because that's what the power supply is sagging down to so well

[02:13:16]   I can do that I think that's just a percentage thing isn't it 3.8 / 3.6 equal 1.05 so 1.05 time 56,000 equals 59,000 either I did the math wrong or or what black horse said is

[02:13:48]   correct oh that's interesting o oh I mean it's kind of doesn't matter because even though we're seeing on the on the a loaded thrust test the same the same RPM from a 32,000 KV motor to a

[02:14:16]   36,000 KV motor for anybody that's flown a 70 to 32,000 and a 36,000 the 36,000 100% makes more power it's just it's obvious you can hear it in the RPM you can feel it

[02:14:32]    so o o interesting stuff super interesting stuff trying to wrap my head around it I think that my guess is that the battery is sagging in in Flight the battery is

[02:15:13]   sagging down lower than what we can see that's still my guess I've got what's the next motor we're going to test wee bed FPV 0702 32,500 this will be interesting this should be exactly

[02:15:30]   the same as the 32,000 but it only takes a second to bolt a couple up and try them so let's do it I am Walter says is not in CLI dump what's that mean what are we talking about

[02:15:57]   Walter so when I'm holding the quad and I go Full Throttle each motor and propeller has to pull static air not moving air and then accelerate it and push it out versus when I go hauling across the

[02:16:16]   living room there's 10 20 30 40 mph of incoming air so I would think and I this is the the I thought this was the common knowledge in the tiny whoop World Maybe I'm Wrong

[02:16:31]   but I would think that that incoming air would allow the motor to spin up to a higher RPM right because the incoming air is easier for it to accelerate the the the air is already going 20 30 40

[02:16:50]   mil an hour so the propeller should be able to spin higher right right which and that makes sense because when we spun up that bigger Stater volume motor that's a lower KV the 703

[02:17:18]   23,500 since it's a bigger stator it's allowed to it's able to push that propeller harder that's it 8bit FPV perfect it would take less energy to spin to that RPM with incoming air right

[02:17:31]    so unless we're running into the to the cap of the motor which we're not because they're spinning right so the motor that we just tested was 0702 36,000 KV right so no

[02:17:49]   propeller on it's doing 120,000 RPM at 100% throttle Right double this because this is 50% here versus with the prop on it's only able to turn 64,000 RPM

[02:18:05]   right crom says you can test your incoming arpm Oh by blowing on the prop when it's full full blast but I agree that's how it should work [@$#%] great yes all right let me bolt one more

[02:18:19]   propeller one more on here and then I'm going to do that but you guys are going to have to look at the RPM I don't I don't know if I'm going to be able to look at the RPM and

[02:18:29]   blow into this damn thing at the same time but we could totally test that good call homie all right Motors one and two are now HappyModel 0702 32,500 this is kind of a silly test but just for the sake of

[02:18:49]   argument comparing tiny whoop 32,000 to we bed 32,500 we the difference should be so small that we can't tell but I mean you never know you never

[02:19:04]   know all right plugging this in and plugging this in I wonder how much air velocity we can make with a with our face and lungs and mouths I might as well bolt on two more

[02:19:24]   Motors while I'm doing while I'm here yes BetaFPV 0702 oh damn it these are 0802 well that's okay these are BetaFPV 802 23,000 come on now 802 SE

[02:19:59]   23,000 bfv 802 23k all right let's bolt two of these on and then we will test that Andrew tayor says use your hair dryer on the prop I wouldn't I bet you I can blow

[02:20:23]   harder than a than an air dryer a hair dryer I personally don't own a haird dryer I'm sure Maggie does but it's all the way upstairs damn I wish there were a set of beta fpv7 02s in here but this is

[02:20:39]   okay because what is this 23,000 KV whatever as we get more and more data this will just kind of beef up and we'll be able to really see some of these things kind of changing this is

[02:20:53]   totally fine right plugging this motor in and plugging this motor in kin some says a hair blower will blow more consistently than you for a lot longer that's true that's true but I

[02:21:19]   want to get a burst of I I I want to get like a big burst of wind going in and see I want there to be like a big change if possible that would be cool all right I'm going to put like the

[02:21:35]   RPM full screen for you guys and then you'll hear me hopefully you'll hear me what I'll be able to tell by the RPM of the propeller I'll be able to hear the propeller spin up to a higher

[02:21:45]   RPM I'll bet you or lower or lower black horse says if you fly into the wind are you going slower or faster it depends on if you're talking about ground speed or air speed ground speed

[02:22:05]    you're going slower okay props off test first we've got why is this motor all bound up is this motor all bound up that doesn't feel right at all well this one's not even plugged in

[02:22:31]   I think two I think these motors might be rubbing on the on the frame here but hang on let's just try it we will know right away if it is all right BetaFPV 802s versus we bed

[02:22:53]   72s on the constant voltage source and I can just hang that off the desk all right cool here we go and connect and motors and right zo me guys in this is not the blowing on the thing

[02:23:12]   test yet motor one 49,000 oh no two won't spin that one felt like it was binding up a little bit something's going on with it hold on let see if it'll

[02:23:31]   turn there it goes okay motor two 4 49,000 is that these should be the same 49,000 great 49 yep 49 and then the 802s they are binding up I can just move it around a little

[02:23:59]   bit free it up there we go 30 wind it up to 40 call it 40 40 40 and what did I say 46 wow this is all the way up at 52 hold on 49 maybe that motor is binding up a

[02:24:33]   little bit hold on moving around a little bit wow there we go these motors are binding on the frame a little bit 50 55 Jesus okay hold on just wiggle the motor out and a little bit see if we can get it up

[02:25:00]   to 55 like the other one I'm going to call it 54 I saw a bunch of 54s there so 54 and 40 pretty consistent 40 54 and 40 let's take a look all right 54 and

[02:25:26]   40 okay BetaFPV is doing 40,000 54,000 so okay a little bit under the 32,000 drop hm in there let me take a quick look at this Frame to see if it's binding on these two motors

[02:25:59]   for some weird reason it might be hold up let me back back this screw off here a little bit swear to God if these if these motors have been B up on this goddamn frame 54,000 I just loosened a couple

[02:26:37]   of screws let me see real quick if this makes a difference what I would like to see is 56,000 on these motors because that's what the that's what the tiny whoop Motors did

[02:26:53]   2000 KV seems like a little bit high of a of a difference between these two 52 there it is 55 56 there we go yep yep yep the motor was ever so slightly touching the

[02:27:13]   frame 52 there it is 55 56 got it perfect perfect perfect all right great good good good good good good good good good all right so that was to be expected let's fix

[02:27:28]   that it's because I'm overtightening the the motor screws and then it's pushes the plastic in a little bit I really need to take all of these frames and drill them a little bit

[02:27:43]   these cockroach V3 frames they need to be the the the mot holes need to be drilled out okay so putting propellers on now render says what frame I had to use a larger

[02:27:56]   drill than a regular cockroach frame not just the light one yep me too well sometimes some of the the the Cockroach frames when you don't overtighten the motor screws are fine

[02:28:10]   the Cockroach V3 frame the light AF frame I've had to do it no matter what but the V3 frame as long as you don't overtighten the motor motor screws it's fine once you've overtightened the

[02:28:23]   motor screws a couple of times in a row it squishes the plastic in and it and the the round Center hole the round Center hole you got the three screws here it and it pushes the plastic in

[02:28:37]   like that and then it starts to rub and so I just need to stop overtightening these screws or better case drill it out because when you drill it out it then has enough clearance that

[02:28:49]   even when you crank the motors down you're good to go props are on I need to chop my lips off I need to get the motor spinning the correct direction props in motor

[02:29:10]   Direction understand the risks wizard start and spin motor one is props in great motor 2 is props in great motor 3 is no way motor 3 is wrong I reverse motor 3 now we're good to go though it's going

[02:29:29]   to say no way they're all four of them are right just check it m one is good two is good three is good four is Good Wonderful all right we're going to check I'm going to try to chop my lips

[02:29:44]   off so I'm going to check motor number two I'm going to ramp it up to full beans and I want you guys to look at the RPM before I blow on it and then you'll hear me start blowing on it

[02:29:59]   ready motor two here we go chopping my lips off so 64 64,000 is basically what we keep seeing all right and then I'm going to blow on it ready totally you can totally hear it

[02:30:16]    so it the incoming air does help did you guys happen to see what it wound up to I mean you can easily hear the difference there though okay let's let's continue with the testing so

[02:30:29]   the incoming air does allow more RPM but when we're on the battery it's sagging like crazy versus this power supply that's not sagging at all motor one 60 I saw 64 for up to 65 not that much

[02:30:47]   extra interesting 56 what's happening is the board getting too hot 64 there it is 64 the motors are actually overheating 59 I saw 59 64 and 59 that's what I need to know 64

[02:31:11]   and 59 all right and oops 64 59 okay so what did we just test 64 yep totally expected that there's yet another HappyModel 702 that's maxing out at

[02:31:34]   64,000 on the The Loaded thrust stand and then we've got a BetaFPV 802 and that one did 59,000 KV even though it's only 23,000 KV but it's a big grunty motor and it's

[02:31:52]   able to push that propeller through the static air a lot harder yet more more data to back up what we've been saying there I wouldn't think that I can blow with my mouth more

[02:32:07]   than like I don't know 5 miles an hour maybe 10 miles an hour but I mean we could absolutely hear the the the motors wind up Jason black says is your house windy that I

[02:32:20]   miss something no what we're testing is whether or not these motors turn higher or lower RPM once they have incoming air and we've just confirmed that they will turn a higher RPM this is why even

[02:32:36]   though when we look at a 36,000 KV motor now hold on when we look at a 36,000 KV motor all the way down to a 32,000 KV motor without a propeller on them the 36000 are turning higher as you would

[02:32:53]   expect but then once there's a 1210 propeller on there they're turning the same RPM it's because this is on a static test in the air you can absolutely feel the difference in power

[02:33:05]   between these 32,000 and 36,000 and also the 40,000 as well see even the the 40,000 we're only getting an extra 500 RPM with the propeller on but look at the difference without the propeller on

[02:33:18]   obviously the 40,000 is turning more RPM it's wound higher but once the and there's a definite difference in power between the 36s and the 40s in the air so I mean [@$#%] A bunch of you

[02:33:35]   guys have flown 32,000 and 40,000 and you can all back me up that there is a massive difference between those two but look at the RPM numbers 64,000 versus 64,500 that is that is a tiny percent

[02:33:49]   percentage change that's like a 1% change you wouldn't be able to tell 1% more power there is way more than 1% extra power between a 32,000 KV 702 and a 40,000 KV 72 it feels like there's

[02:34:03]   twice as much power so there you go crom calculated 65,000 RPM on 1219 propellers we be pushing Air at around 8 MERS per second which is 18 miles hour that seems a little low

[02:34:20]   18 miles an hour that seems super low doesn't it I would think it would be way higher than that but I mean I I'm basing that on like nothing that's just

[02:34:32]   like based on gut reaction which is never right never trust your gut ever Juju says I got the Mobula 6 elrs not the 2024 because it's got proven 2g4 but it weighs in at 18.7 gram their

[02:34:49]   upgrades beside doing the antenna mod let F frame to make it lighter nope that's about it the 2g4 is a heavy AO but it is a super reliable AO and with a 32,000 KV or

[02:35:06]   36 or 40,000 KV motor it moves that thing around just fine so that you've got like you've got sort in in current time whoop terms you've basically got like a 750 gram 5 in rig you're hauling around like a a

[02:35:27]   GoPro 12 and big old 2207 Motors and you're on like a like a 140 gr frame that's sort of the equivalent of what you've got there if you go air

[02:35:42]   65 or Mobula 6 2024 you can have a 650 gram or a 600 gr Rig 5 in experience basically you can get down to 17 point something grams even 16 point something grams but there is nothing wrong with a

[02:35:59]   2g4 just go go bigger motor it's arguably more fun okay so tested these what are these motors here some 1102s these are going to have the bigger motor shaft though aren't they no that's

[02:36:18]   a 1 mil shaft isn't it oh [@$#%] we're about to go totally crazy and test an 1102 I think is that ah nope Noe Noe different motor shaft all right we're going to wait

[02:36:33]   we're going to wait on the 1102 testing because we're going to do some of this testing with the 1610 byblade propeller because that propeller is available in 1.5 mm motor shaft and

[02:36:47]   it makes more sense for the bigger Motors but what's insane is how much drag this 1210 propeller is putting even on these bigger Motors it's really cool to see these bigger Motors push

[02:37:02]   these little tiny 1210 propellers so much harder I didn't expect that what other motors do we have to test 29,000 KV newbie DRS we already tested those what do we got here

[02:37:21]   this is a 702 30,000 we haven't tested that yet but we've tested Motors they're very close to that kind of do want to test them what else do we have though that's one

[02:37:35]   mil shaft n let's oh oh I do have some 34,000 yeah all right so these are old school prototypes man Jesse sent me these forever ago probably like two years

[02:37:54]   ago 702 34,000 KV awesome all right let's bolt couple of these guys up I flew the [@$#%] out of these he sent these a little bit after the 32,000 KV Motors originally came out to see if it

[02:38:11]   was worth it to go higher than 32 because they was at the time I think he still is working with Ethan for micromotor test Labs who has a static thrust stand and Ethan was telling

[02:38:30]   Jesse I've I've tested Ethan was testing these higher KV Motors and they exactly like we're seeing here they weren't turning any extra RPM above 32,000 KV

[02:38:44]    and so it was like it took a minute for them to kind of realize well there's no incoming air and that's going to affect the the test results static thrust stand results are

[02:39:02]   awesome but they're not the full picture which I know we've been saying for a while but this this is absolutely proving that because it is unquestionable if you've flown 40,000 KV 72

[02:39:20]   that they make considerably more power oh man I can't wait to see what these what these 34s turn render says would going from a higher KV and motor limiting to a larger size

[02:39:41]   battery lose efficiency Aton it negligible technically motor limiting is going to lose you a little bit of eff but I've found it to be negligible I tested the [@$#%] out of that at one

[02:39:57]   point to and I've tested it on 5 in rigs I've tested it on Tiny whoops but what you don't want to do is go completely crazy like you don't want to get 40,000 KV Motors and then scale them

[02:40:10]   down like 50% that's too much you've gone too far in that scenario all right 32,500 over there there okay so I've got 34,000 KB Motors here that I'm putting on what are

[02:40:24]   these oh 603 30,000 this will be very cool 603 30,000 some more prototypes that Jesse has sent very very very kindly sent me maybe oh I'll I'm going to be the results of this going to be

[02:40:50]   pretty cool because we've got like 703 we've got 603 we've got 802 we can really see I don't know what we're going to see I'm gonna have to think about like once we get all these numbers I'm going

[02:41:06]   to have to really stew on this and see what I think a lot of this kind of means but that's kind of exciting is everybody completely bored to tears is this the the worst live stream I've

[02:41:22]   ever done I thought we were going to see more variation in the in the non-happy model Motors this is also super super cool to see what the the the rated KV is versus the actual KV

[02:41:43]   I'm not I'm not testing the KV in the best way possible here the best way possible would be one of the best ways to do it is to spin the motor and then read the voltage coming out of it

[02:41:58]    I don't have the setup to do that some other guys do I think is it Cloud Hopper I think built a little jig to do that because he's the guys that are hand winding these tiny whoop Motors

[02:42:12]    it benefits them to do that because they're in a Land of Make Believe just like well let's try winding it five times and there six times six 656 565 like 7 six6 so for those

[02:42:29]   guys at rules all right let's see here 603 versus 702 30,000 KV versus 40,000 KV and let's get this going here all right I can just let this guy hang okay Motors and we want 50% here we go I

[02:42:58]   don't even know which one this is oh [@$#%] not spinning why ain't you spinning all right it's kind of B let's bind that on the frame again damn it

[02:43:22]   hold on whoa yes you got upset by that I need to drill this Frame out I need to well let's do this let me do this let me fire these motors up I'm going to record the numbers that I get

[02:43:41]   and then I'm going to drill this Frame out and then I'm going to run this again that should tell me if the frame was kind of screwing me over it's weird like if I if I grab the bell of the

[02:43:55]   motor and wiggle it around a little bit all of a sudden it's spins up totally fine I think now that I'm not cranking the motors down they might just be like barely touching on the

[02:44:13]   frame all right so let's see 46,000 see that motor number one's Dragon for sure 56,000 that's to be expected kind of 56,000 all right now hold on I I gotta drill the frame out it doesn't make any

[02:44:38]   any sense to keep going with this Frame possibly rubbing damn it turds all right hold up wow we're coming up on three hours Jesus that's okay we're hanging we're

[02:45:15]   doing I don't know can I can I say that we're doing science or are we we're I mean I guess kind of we're doing science but we're doing like the most broy version of science ever which is why I'm like

[02:45:31]   are we doing science but I mean we're doing something is the 702 chat is absolutely on fire right now black horse says maybe I'm thinking thrust static thrust is the max

[02:45:58]   you can get that and dynamic will eventually reach zero the faster you go I mean like if you get if you blow enough air if you blow enough air incoming air on these

[02:46:10]   motors they will they will hit that eventually they'll hit that maximum RP p m that they're able to hit with no with no prop on right is is a like an extreme way to think about it because

[02:46:28]   the incoming air will match the outgoing air and then the motor will just be able to spin totally freely a screw just vanished on me there it

[02:46:40]   is damn guys when when you get a cockroach V3 or light AF frame drill it out ASAP drill it out as soon as you take it out of the box in order to drill it out you can't have the you

[02:46:54]   don't want to have the motor screws in it either so just do them as soon as you get them out of the box it's the name my sex tape Cloud oper says I sent you my test stand if you want to B I could send

[02:47:11]   you my test stand if you want to B for a bit nah we're good I I'm I I'm getting the the data that I'm kind of hoping to get I I think this is I think this is relatively accurate here

[02:47:24]    getting the the exact KV won't necessarily like I'm testing all of these motors in the same way and what I'm interested in I'm not interested in the exact number I'm interested in the

[02:47:40]   relationship between the different Motors right and since we're testing them in the same way each time I think think that it's relatively accurate and we're we're rounding off to like a

[02:47:55]   th000 RPM I'm not trying to do really do like 56,500 RPM even even I've done it a couple times but for the most part like we're keeping it pretty rough

[02:48:07]   here I appreciate the offer though brother I knew it was you that set up that little stand come on there we go okay cool all right all four of these guys are off I actually still have the the drill and

[02:48:27]   bit sitting right here next to my desk so let me real quick just zip these opens put it in there by hand first don't just crank away on it you can very

[02:48:41]   easily rip the the motor base right off the the little standoffs so just hand jam it first little bit of hand jamming never hurt anybody and then spin it up and pull

[02:48:57]   material down pull pull pull the material down this way screw drill it like this so that you're not pulling material up to where the base of the of the motor is going

[02:49:07]   to be cuz they're going to be little hangy ball bastards and I fired it up to full speed to get it to wobble around a little bit to just take out ever so

[02:49:18]   slightly more material this is a 964 drill bit and it's pretty much Perfect all right good to go all right let's both these motors back on and of course I don't remember what

[02:49:37]   those numbers were that we ran a minute ago but I mean that that one motor was definitely dragging what I mean so I don't think we need to doubt whether or not that needed to be done just

[02:49:56]   now hard part's going to be getting these screws in here notice says it's like a Springsteen concert what what does that mean what's like a spring steam concert cler says you don't need a multimeter

[02:50:22]   that can read ac voltage I've I've got that I just there's I just I I don't necessarily care about the the the exact KV again I I appreciate the offer

[02:50:40]   though crom says could you test one 102 so we can see how much way too much torque means the difference between unloaded and loaded I can't because all of the

[02:50:57]   102s are 1 and a half mil motor shaft and so I can't put this same propeller on there so I would have to put a 1610 propeller on there and that's a whole different thing so we're going to

[02:51:11]   have to do the the the one and a half mil shaft testing kind of separately basically oh or I can try to drill out I have tons of these GemFan 1210s I might as well try to

[02:51:27]   drill a couple of them out to 1 and a half millimeter they don't need to be balanced they just need to go onto the motor I'll do that I'll drill a couple I'm not going to do it now but

[02:51:40]   at some point here I will drill out a couple of a couple of 1210 so that that's a great idea because then we can as we as we continue to go bigger on the Stater size

[02:51:59]    there has to be a point where a point of sort of like diminishing returns in terms of a prop on static test here hopefully that makes sense is there a little piece of plastic

[02:52:17]   in there get the hell out of there get the hell out of there little piece of plastic come on now there it is doing this in a hurry usually I'm a little bit more careful at

[02:52:34]   this y y n it's fine it's not in there it's not touching it this one now we're good there's visibly clearance now between the frame and the

[02:52:57]    and the C clip on the bottom of the motor the the problem is that the c clips that newbie drone uses on their Motors the outer diameter of those c clips is ever so slightly smaller than

[02:53:13]   the c clips that HappyModel uses so putting newbie drone Motors onto your newbie drone frame all as well you don't have to drill it out or anything but HappyModel is using a

[02:53:24]   slightly different C clip classic case of aftermarket things from one company not driving with aftermarket things from another company something that happens in the world of

[02:53:39]   cars all the goddamn time because each different aftermarket company designs their stuff to be to like fit tighter on the stock chassis or the stock engine and then when two companies and then so

[02:53:56]   when you buy one thing from one company that that closed up a gap and you buy another piece that sits right against it from another company that closes up the Gap now those two butt heads and like

[02:54:09]   they can not fit sometimes and it's super annoying it happens with suspension components quite a bit but you get like a you get like an upright from one company and then like a ball end from

[02:54:23]   another company and they they won't work with one another you can either use the the stock upright with the ball end from sta or the ball end from sta with or the aftermarket upright the aftermarket

[02:54:37]   upright from Maximum Motorsports with the stock ball joint so a lot of times it pays to stay with the same manufacturer get all of your stuff from Maximum Motorsports cuz

[02:54:49]   their stuff is all designed to work together okay the frame is now drilled out there's a visible gap between the c clips and the plastic so now we don't have to worry about that

[02:55:06]   anymore and we are testing 0603 30,000 versus 0702 34,000 no props first I know I'm missing chat comments guys I apologize but I'm trying to get through as much of this as I possibly

[02:55:26]   can live so we can talk about it okay motor one I didn't plug any of the motors back in I bolted the motors down I didn't plug any in so to talk a little bit more about

[02:55:54]   like the the inconsistencies that we've got going on between all of these one of the inconsistencies is going to be that some of these motors I have plugged and unplugged a bunch of times so but

[02:56:08]   we're actually not seeing that much inconsistency between these I've actually been pretty pretty Blown Away by how consistent this testing has been but for the record how many times

[02:56:18]   the plugs have been plugged in and out technically this AO is getting is heating up and cooling down that could maybe affect the fets a little bit here and there

[02:56:32]    I think those are the two biggest sources of lack of consistency all right here we go Motors 1 and three are the 702 34,000 I'm sorry not one and three one and two rather come on B FL you can do

[02:56:56]   it yay no wrong tab there we go here it is and let's test 52,000 Jesus 56,000 there's a huge difference between these two 34,000 KV Motors let's try the 60330 is

[02:57:23]   56,000 56,000 okay so hold on 56 for the 0603 hm 0603 30k I don't remember what I just said was it 36 no it wasn't what the hell was it damn it 56,000 that's it

[02:57:57]   56,000 okay 56 comma o that lines up with these 32,000 KV Motors 30 32 close enough let's check out these 34,000 KV Motors though again 55

[02:58:15]   56 56 there we go there we go but now it's winding up to 59 this one's really sticking at 56 motor one seems a little weak here let me move the Bell around a little

[02:58:36]   bit okay let's try it again 57 I saw 58 we're going to say 58 we're going to say 58,000 KV yay that tracks 58 oh oh oh perfect that's exactly where it should be awesome all right now we're going to

[02:59:00]   put props on and I'm just going to do that real quick here Pops in doesn't really matter but as well okay ouch poops in and I know I know I know I know I know it's beeping esc's been on

[02:59:30]   for two minutes it's like arm me [@$#%] all right there we go props are on let's see what happens here wait no I got to get them spinning in the right direction first

[02:59:46]   stop motors motor Direction understand the risks wizard start spin great motor one is correct motor 3 is correct motor two is wrong click it to reverse it motor four is

[03:00:04]   correct should all now be making thrust let's check them in in in in great motor one 64,000 go figure motor two 64,000 go figure now here we go this is interesting 65,000 65,000 64 and

[03:00:33]   65,000 all right let's see 64 and 65,000 hang on 64 and then 65 so 34,000 KV 702 versus turning 64,000 KV with the propon 30,000 KV 4,000 less KV but 603 is a bigger Stater volume

[03:01:04]   getting up to 65,000 KV what else is turning 65,000 KV so look at this VCI oh look at this man look at the difference in stator volume here a VCI 070 3 which is a

[03:01:19]   significantly bigger Stater than an 0603 only 23,500 KV was cranking up to 64,000 a 30,000 KV 603 could barely get to 65,000 that's pretty cool stuff 603 is not that big of a of a

[03:01:39]   stater it's not that much bigger than 702 here I'll show you we've got 0702 is the smallest and then we've got 0603 which is slightly bigger and then we've

[03:01:58]   got 0703 which is even bigger yet right and so look 702 77 70 603 85 703 115 look at the size of that jump and then the the surface area the 603 actually has less surface area than the 702 but the 603

[03:02:22]   has got that extra volume so 703 is a massive Step Up compared to 603 and obviously 702 oh baby six o'clock it has been three hours Juju says I have a tiny hwk freestyle

[03:02:41]   three analog that falls out of the sky or flies to the Moon without me disarming full throttling says bad RX feel safe is there a way to fix other than a new receiver Juju that's a there's all

[03:02:52]   kinds of different I I can't just like give you a one quick answer Andrew Taylor says is having a bunch of hair caught up in Motors going to affect efficiency a lot my flight times have

[03:03:03]   dropped it's could but the way that the the way that these brush brushless motors are set up the hair typically winds around the bottom of the Stater and doesn't touch the Bell so unless

[03:03:19]   there's a lot of hair on them I try to keep the hair out of them but the the brushed motors were way worse the brushless motors don't care nearly as much about hair but it still does matter

[03:03:33]   especially if you get a bunch of it clogged up there so it's could be a part of your problem all right three hours is too much for a live stream so I'm going to chop the live render

[03:03:44]   says what size build drill bit do you use 964 I'm going to chop the stream here I'm going to do some more testing to keep beefing up this Excel spreadsheet what I'll do we'll do a

[03:04:03]    do I know how to do that anymore no I want to listen to some music I was going to say we'll do a patreon only stream but I want to listen to music and watch YouTube so

[03:04:15]   we've talked through a lot of this stuff I I I really need to just sit down and stare at this a whole bunch massive thanks to Kevin suner for doing some Excel spreadsheeting things and

[03:04:29]    c fpv.one and then tomorrow night is giveaway night but I'll take 10 or 15 minutes to talk about what I've molded over tonight I'm actually skipping dance class because I don't want to re hurt my

[03:05:02]   back so I've got all night just sit here and nerd out so thanks for hanging friends I hope you learned something I certainly did and I hope I can continue to figure some [@$#%] out

[03:05:14]   from these results love you bye I'm not ready we didn't I know we didn't fly let me fly another battery fly one more battery we flew a 36,000 KV battery let's fly

[03:05:32]   a 32,000 KV battery on the 36,000 we turned oh different propellers though so it's not going to be a one toone test but 36,000 KV motor with a battery we turned 56,000 KV let's see if

[03:05:51]   this with a different battery which is a problem let's see what this will turn KV wise the internal resistances of the batteries are are different and so this is this doesn't really tell us much

[03:06:06]   but it's an interesting thing to look at isn't it and I'll fly around 32,000 KV rig with triblade HQ YOLO props on it what could go wrong all right here we go oh God change the oh

[03:06:27]   nope I just have to hit okay on the transmitter I might have to change the module no we're good here we go let me actually see what that turned that Quick Throttle blast turned 55

[03:06:48]   ,900 let's see what this will do here God it is hard to do this it's hard to do it without crashing all right let's see what that was 58516 so the problem is we all

[03:07:09]    oh oh oh look at the minimum battery it saged this battery all the way down to 3.5 volts oh I'm going to go back and I forgot that I had the minimum battery in the oh I might not

[03:07:19]   have had it in the OS the other OSD but can hold on we can do the math oh can somebody in chat do the math if the minimum battery is 3.5 volts and it turned

[03:07:34]   58516 RPM what would the RPM be at 3.8 volts can somebody do that math for me while I fly the rest of this battery W boy that was weird looking wasn't it oh God

[03:08:01]   no oh I got very lucky on that one these HQ Tri blades fly great man it is no surprise that the racers dig these ah get in there oh rejected oh boy

[03:08:27]   Plinko no no no easy tempting fate above the kitchen sink oh God close one oh this battery's done battery has a little bit of juice left in it but it's fine can anybody do

[03:09:04]   that math 6353 oh look at that so that's right up to that's back to 64,000 damn why are we not maybe I'm just not maybe the living room is just not big enough to really let it or maybe like

[03:09:24]   the voltage I don't know I don't know very weird I would think that it would turn much higher RPM than that once it's up in the air but maybe we're just not giving it enough

[03:09:41]   space maybe it needs more space than what what we're what we've got in the living room but man it's is hauling ass by the time it gets to the other side of the room isn't it like one would

[03:09:55]   think that would be enough space huh those are both 2g4 rigs so 18 something grams you know the deal all right friends thanks for hanging the learning continues

[03:10:18]   be good I'll check you out tomorrow night at 10 o'clock Eastern time for giveaways and a recap of what we may or may not have learned in this here's some 0802 25,000 KV GemFan 1610 jungle gem

[03:10:36]   Basher flight footage for you love you bye see you guys tomorrow night n n n n a
