MASSIVE 65mm Tiny Whoop Motor Test!

[@CiottiFPV]

GREAT testing of 1mm shaft 75mm Whoop motors here with a few suitable for 65mm builds as well, looking forward to round 2 with the more current/popular motor choices for 65mm builds from Tiny Whoop, We Bleed FPV, BetaFPV, and NBD

[@GarethDix]

Would love to see how the webleed screamers test… they made a huge difference on my mob6 HDZero

[@weBLEEDfpv]

@@CiottiFPV 🩸 🙏

[@CiottiFPV]

@@GarethDix $10 says they'll make the same amount of thrust as the RCinPower 0702 29,000's but with better efficiency, HappyModel motors run at much lower kv than they're marked so the Screamers at 32,500kv will proably only turn 29,000ish just like the RCinPowers

[@Tokyo_Dom]

​@@CiottiFPVlooking at the other numbers I'm expecting those to be closer to 25000kv "true kV"

[@CiottiFPV]

@@Tokyo_Dom I tested a set on my spreadsheet streams last week and they were 28,000

[@CiottiFPV]

00:08:31 - I'll bet this is because the thickness of the copper windings is optimized for this low kv variant of the motor. For anyone that doesn't know what I'm getting at, it's very common for the manufactures to set their machines up with the thinnest wire for their low kv motor and then not retool the machine with thicker wire for the higher kv versions of the motor which use less turns per stator pole

[@quadFun-o4t]

Since the test rig is done, will be fun to see how much thrust those motors give on 41mm, 50mm and 65mm props. Light biblades.

[@661FPV]

Great video Chris! Please include the Webleedfpv motors in your testing, I would love to see the actual KV of the motors vs what they are labeled. 40000kv, 32500kv, 28500kv, 26500kv, 24500kv. And also looking forward to the tinywhoop motor testing, my favorite motors are the 0702 30,000kv from tinywhoop.

[@mikebergman1817]

Epic testing. Thank you Chris.

[@baggszilla]

Chris you need to do the WeBleedFPV Motors with the TinyWhoop motors! I'll see if I can get in touch with ZOETEK to get a hold of you! Cheers!

[@dadada435]

So the motors with ball bearings are the most efficient. It would be great to have a direct comparison, e.g. the BetaFPV 0702s in 27000kv with bushings and bearings.

[@qual-der-walfpv6841]

The weight of the Motor is another aspect to consider, especially in this field. Would be awesome if you could provide this information.

[@АндрійАлєксєєв-п3з]

I'm using rcinpower 0802 on my 75mm with biblades, and i like it. Sometimes I even fly it with 300 mah folded cells battery, and it's complitely fine. They're also pretty durable, I used to use old happymodel motors, and they had their shafts bending and rotor separating all the time, but rcinpower never does that

[@superdstar2001]

This is incredibly interesting. Looking forward to the video with newer tinywhoop motors. A lot of the Happymodel motors on here are 3-4 years old. My favorite is the RS0802 20k, which is the newer version of the 19k you tested. Thanks for all of your amazing work!

[@ItsRenderInnit]

You should pull in the webleed motors too, the 32500kv and 40000kv are great contenders when talking about the tiny whoop motors too

[@imothy]

my favorite motors are the tiny whoop 0702 36,000kv motors. I use them on a 65mm walksnail build at 80% throttle limit and I love flying this drone!

[@tinywhoopfan]

Have you tried the webleed 0702 32.5kv? I run them at 100% throttle limit and get 2 minutes flight time on 300 mah freestylin

[@imothy]

@@tinywhoopfan I have not, i don't do any hardcore acro just cruising around usually get about 3 minutes on a 300mah battery if I set things to 100% I will brown out the walksnail vtx on a punchout lol.

[@Tokyo_Dom]

​@@imothyif you are just cruising around you don't need that high kV. You would get longer flight times with a lower kV and not lose anything out of it (higher kV uses more battery at all throttle levels so it doesn't matter if you put a limit on it, will still be less efficient than lower kV)

[@imothy]

@@Tokyo_Dom True, but I do like having that extra headroom that I don't use, but the PID controller is also able to operate in that zone, so I can dial in my cruise smoothness with the higher KV. And allthough I am cruising, i like doing building dives, so it really helps having that power to recover out of dives.

[@Tokyo_Dom]

@@imothy it really isn't necessary, for building dives or for the pid controller (unless you are trying to stop the dive at the last 0.5s, which doesn't look great anyway), but it's your quad so if you don't mind the shorter flights then that's fine.

[@turboomni848]

That's a lot of work. Thank you great job

[@ndisa44]

Very interesting yo see that many of the high KV HappyModel motors test at a lower KV than claimed. Those motors have been known for being impressively efficient. Seems that makes sense if they are lower KV than claimed.

[@CiottiFPV]

I did some testing on my streams last week that showed this as well, their motors are the efficiency kings but you need to buy a slightly higher kv

[@ndisa44]

[@jamesjenner3584]

Amazing video Chris, been waiting for this one. Cant wait for the next in the series. Big thank you

[@Tokyo_Dom]

Great test Chris. Not sure I agree with the final choice considering it's highly weighted towards power, all the top thrust motors were also all the most inefficient by a large margin. Some pilots put more weight on efficiency, so it would be good to have two scores - one for outright power and another weighted towards efficiency

[@minirollsrule]

Great video! I have rcin 0802 27000kv motors on the way from Ali, nice to see i didnt make the worst decision!

[@Galileocrafter]

Normally we (the company I work for, not drone motors) measure kv at the nominal voltage with no load. It’s not always as linear as you’d think but a measurement in the lower 10-20 % and at 100% nominal Voltage should give you a good idea what’s going on. Oh and +- 10% for the kv value is fair.

[@danieldewindt3919]

hahah that is a grate initiative! Finally some comparable test results. :)

[@scottmilano2940]

One thing I’ve always wondered about the Higher KV 0702 motors was whether they had the torque to actually spin any faster with a prop attached. Apparently some do. I was worried I wouldn’t see the motor weight to performance comparison, but you did get that at the end. Order placed, thanks for all the great info!

[@CiottiFPV]

They do once they're moving through the air, on the thrust stand with static air they need to pull in they don't but you don't fly FPV with your rigs bolted down to your desk right? ;)

[@scottmilano2940]

⁠@@CiottiFPV At the bottom of a power loop is where I’d want the extra KV. Certainly they’re (happy model and betafpv 25000+kv) better, but I wonder if the top RCinPower 0702 motor here will be even better. Sounds like a live stream if you haven’t done it already. :)

[@CiottiFPV]

@@scottmilano2940 The HM 0702's make more and more and more power all the way up to 40,000kv with much better efficiency than RCinPower/NBD/VCI/BetaFPV I get 3+ minutes blasting around the basement on my streams with even the 40,000's that make TONS of power

[@mikequill9638]

I was unsure about the t-motor 0802 27000kv motors I had just ordered this morning until watching this video. Seems like they scored pretty well in all categories. I'll be using them on a 65 pro frame with an hdzero eco and 12a esc. Thanks for all your thorough testing and analysis!

[@Dronstah]

Would be grate to see some higher kv testing, 32000 kv tinywhoops, 32500 webleed, 40 000 webleed. To see if it's worth it to go for a higher kv

[@butterflyfpv]

GREAT WORK Chris!

[@АндрійАлєксєєв-п3з]

its ok, i use rcinpower, 75mm biblades flies about 4 minutes with 450 mah battery

[@siskel82]

I've been running 16500kv 0703 on a 75mm 2s walksnail build and they definitely have the responsiveness

[@BreeZieDoesiT]

Great vid. Always wanted this type of vid for whoops

[@mad_caterpillar7725]

great breakdown! i delta terminated the tmotor 703's at 1.6g to 33000kv and they're amazing, no tiny whoop motor holds close to raw power!! I'm testing 702 36000kv delta terminated instead of tinywhoops wye termination and its a night and day difference. Delta seems to pull more on startup but less overall amps so maybe the 1a efficiency test is biased?

[@yevhen_unknown]

Thank you so much.

[@itsjase92]

Love the testing, but I think the efficiency weightings might need to be done slightly differently if we are trying to determine the "best" motors. eg. On an identical setup with a 300mah batt, the RCInPower 27000kv give me maybe 2min flight times, whereas with the happymodel 28000kv or betafpv 27000kv I get 3-3:30. I know the RCinPower provide a lot more power but this kind of trade off in efficiency is too much of a sacrifice in my eyes.

[@alexanderkolyshko]

Strange. I have RCinPower 29000kv in my air65 setup and I have similar flight time as on betafpv 27000kv motors: 3:15-3:30 on LAVA 260mAh. I'm using preset from Chris Rosser for tiny whoops BF 4.5.

[@ddxdezx]

Thanks so much for sharing the testing! Could i request the betafpv 0702 (non-se) 30/27kkv for the next round of testing?

[@martianmcfly]

HGLRC are the ones to pick guys 👽

[@Dunkelstrasse]

One motor seems kind of odd to me, the RCinPower 0802 27kkv performs worse than lower kv versions of the same motor. A friend of mine has a pair of these and i hate them, they are almost impossible to tune on any rig, the esc keeps overheating and they kill the 300mah batteries way faster than anything else i have seen. And seing how they compare to the lower kv versions, makes me think that they might have some issues.

[@ChrisRosser]

This can sometimes come down to the exact wire diameter used in the motor. Sometimes going to a higher KV doesn't allow thicker wire to be used. Then performance can suffer.

[@ChrisRosser]

Phew just got the links in the description in time! 🤣

[@v-227]

What ESC and Bluejay settings did you use for this testing?

[@recklessfurytv]

You mentioned that you tested at 3v and divided by 3. Do you know if they produce different kv's if ran only at 1v or if ran at 2v and divide by 2? And if you know, how much of a variance is there?

[@athenovae]

just in time for me! I’m not flying whoops rn but did before. I got back to flying RC planes and am converting a 2CH F-35 from AliExpress to a DIY EDF with 31mm props. 😀

[@athenovae]

looks like RCinPower 0802 22K or 27k would work for me ^-^

[@GK-dd5ci]

The real question is variance of KV.

[@john7402]

Hi Chris, please watch this video I just posted. I lightened an O3 air unit beyond the ultra-lite level, by removing the bottoms of the shield cans from the board, and modifying the copper-tube dipole antennas. May even remove the plug later and replace with directly soldered, very light wires for an additional 0.5g. Please look for the latest posted video under my name, it won't let me post a link for some reason. I may need some help rewinding an 0702 motor to work with 2S power without a throttle limit, if it can be done. I have 0.10mm and 0.15mm magnet wire to do the rewinding, can't fit any more of the 0702 original 0.20mm wire on the stators otherwise I'd do that. There was 5 or 6 turns on each of the 9 stator slots, I'm trying to go up to 10 or 12 turns, impossible with the 0.20mm wire. The motor was originally wound in a WYE arrangement (not DELTA), which is rare for high kV motors (28 or 29k originally). As is, the 0702 motors get extremely hot, even with a throttle limit, on 2S (especially HV) power, which really shortens flight times because of wasted energy as heat, even if they don't burn out. I had to go to 0802 - 16,000kv motors to get reasonable flight times, (slightly above 4 minutes for a 65mm whoop carrying an O3 air unit, 31mm Azi props), but may be able to achieve better times if I can rewire 0702 motors if they can still be kept close to the original weight of 1.5g each, I can probably go up to 1.6 - 1.7g if needed. The 0802 motors (4 of them) are quite a bit heavier. Your knowledge of motor design would be appreciated. Thank you Best regards

Wise man said once "In the future there will be more past, but In the past there was more future Chris... "

[@alexanderkolyshko]

I understood, that this is not a forum :), but maybe someone can help me in choosing props for RCinPower 0702 29000kv. Issue, that these motors have very short shaft: only 3.2mm instead of ~5mm on happymodel 28000kv or betafpv 27000kv. And only one props are fit OK - Gemfan 1208-3. Gemfan 1210-2 doesn’t hold at all on the shaft. Gemfan 1219-3 can be used, but it often flies off the shaft during crashes. HQ 31mm Ultralight 3-Blade Propellers - the same thing as for Gemfan 1219-3. I'm taking about totaly new props.

[@Tokyo_Dom]

I've asked happymodel about their kV testing before and they said they check the rpm at 1v. It's probably this lower voltage which ends up messing with the numbers. But it's interesting they are consistently lower. They have always been regarded as the most efficient, but it looks like that's because they are lower kV. And I thought rcinpower understated their kV but it's the actual kV 😂

[@NeilKagan]

This may be out of place, but you dropped a hint at the new 7 inc long range frame😮. I want to see it but at the same time just got the 7ul in a few days ago. I haven't even started putting it together. Is it gonna be worth waiting for the new frame?
