My biggest motor test yet!: The best motors for Ultralights, Cinewhoops and Freestyle! 

YES YES AND YES......the one I personally been waiting for :)

Fantastic! I have been looking forward to this one. Thank you!

Very good review ! Cheer man appreciate ❤

Out of all the motors I have tested , I still go back to Tiger, for a light efficient 5inch the Tiger 2203.5 is a clear winner. I am able to get 55 minutes with a 4s 21700. I was so hoping you were going to test this motor ;-). maybe next time.. Cheers!!!!!

Great video~

amazing video, great explanations and clarity on motor choices. It’s even better when your results match some of my other fluke choices 🤣😂🤣

I've been in love with amax 2005 2200kv motors on 6S. Just love the 2005 size. Wish rcinpower would make a 2105.5 2150kv motor with 5mm shaft. Would be perfect for 4" freestyle or 3.5" 6s cinewhoop

Thanks!

great test and thanks. difficult to find this kind of video. wish you will have a video to test smaller drone motors. example 2 inch 4s motors (12xx to 13xx maybe?)

This is so cool. Hopefully a tiny whoop test to cap it all off. The smaller you go the more I think you'll be able to find some variety and ideas for optimization. I recently built on an AOS 3.5v5 frame and used RCinpower Smoox Plus 1404 3850kv motors (9 grams ea.) paired with HQProp T3.5X2.5X3 propellers & using 4s batteries. I have no idea if this was optimal but it'd be nice to hear what you think, @ChrisRosser. I'm also curious if you'll find optimal settings for ESCs with these smaller motors as well.

Hi Chris, AMAZING testing! Thanks!!! At 12:21 you made a small "typo" talking about 4 inch instead of 4s ;) What would be interesting is to look for a smaller than 2004 motor to drive 5 inch 2 bladed props to.bring the ultralight weight down a notch. Do you foresee any motor? I Reckon it's very specific....

I would have liked to see the Ummagawd Aerolite 1605 3600KV Motor

Thanks for all the testing. I've purchased your AOS 2207 and 2807 motors. The spec sheet shows that the 5 inch motor draws almost 50% more watts than the 7 inch motor at full throttle. I figured spinning a bigger prop meant the motor was doing more work. Can you explain why the 5 inch motor was drawing 60 amps and the much larger motor was only drawing 38 amps?

Hi, what motor would you recommend for the fastest direction reversal? Iflight 2207 are not fast enough for a custom mixer craft that I'm PID tuning. Thanks!

Chris, is there a UK stockist of the AOS 4 evo frame?

great video as always. I wish there was more explanation on why the kv determined the prop category. It does not mention why none of the motors tested are suitable for 4S 5" ultralight, or why 6s is not suitable for 3.5" freestyle. Apart from that I find it really annoying that manufacturers don't publish the correct KV and your work is very valuable to help us better chose.

Can I use this test for deciding 3” built? I know Chris have a 3” inch test video just wondering if this is applicable for 3” as well

Surprised the aerolite 2004 wasnt on the list. My favorite quad, the 2fiddys default motor.

Would be interested about the Rushfpv 2505.5 and Stanfpv 2604 (made by t-motor).

Strong Work Emax 💪🏽 Probably the least expensive too.

racer star was my first set.

@21:12 I'm out of the loop, whats wrong with BetaFPV?

Mr.rosser they no longer sell the fpv cycle 21mm motors ! I know because my favorite quad is sitting on the shelf with a damaged motor !

Oh!!!! XNOVA even, exciting.

Thanks chris for yet another great test video, although most of these motors don't fit my use case it's still really interesting to learn about them! Question for anyone: I'm having trouble with my Skystars KM55A AM32 esc, set up exactly the same way I have set up all my BL Heli stacks but displaying very wierd behaviour in BF (Esc alarm stays on with Dshot Beacon set to off on default settings, also motor direction wizard makes the ESC restart when changing motor direction). I've attempted to update AM32 to latest (1.99) but esc configurator webapp fails to find the download using the online feature, but also fails to flash the (triple checked) correct target hex file downloaded from the am32 repo... I've never seen behaviour like this before and I could only know about the ESC alarm after soldering (which is usually the point where the warranty stops). Hopefully I can find a solution!

What happened to the 1404 motor recomendation for 3.5“ freestyle? 😮

Great test. Pity that you have not tested even more different sizes. Because for 4" freestyle I have tried more options: (2004 3000KV, 1804 3500KV, 1505 3750KV, 1404 2600KV). For me the results are 2004 -> the smoothest precision flight, 1804 -> Great freestyle but mechanically prone to be damaged by hit because of large diameter, 1505-> Extraordinary power for freestyle, robust but took the most amps on punch (but I stayed with them), 1404 great efficiency for long range. All of them flyable on 850mAh 4S. ' But there is no scientific testing from me and I hoped I would see it here. So I look forward for another tests. Love your videos. :)

So the EMax Eco II 2004 3000kv is looking pretty nice at $13USD/each.

But what if it is not an actual KV lower than the one stated by the manufacturer, but rather just a bad/low-quality bearing? You know that this method of measuring KV is not very correct. Good job btw!

Can we stop with the flat pancake motors already? A 1507 motor has on par responsiveness to a 2105.5 motor which is a whopping 50% larger. Unless your application can't keep a 1507 motor cool for some bizarre reason this is just crazy. Its time we get those tall stator gains across the board already!

Most of these motors are too heavy on a sub 250 build. Brother Hobby 1504.5 is a good balance for sub 250g with GF3630 props. (Any stator volume around 800-1000mm^3)

First

I recommend not believing Chris rosser about motors because I've heard he lies about the data to make his motors seem better just so they will sell more 😢
