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

[@thefreezezone4583]

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

[@ronboFPV]

Thanks!

[@alainassaf]

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.

[@seangordonrichards]

I too was hoping for more insight into 4s 5" quad motors

[@TheGeordietheWitchandtheWench]

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!!!!!

[@TheCANhunter]

Wow can you post a video of your build?

[@dbanks84]

1500kv?

[@dbanks84]

I run 2203.5 1500kv T-Motor on a Tony5 and I get similar times, 35 to 50 mins with li-ion

[@MadfishFPV]

@@dbanks84I’m gathering the props are in view on your feed with a Tony?

[@chrisbee5481]

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

[@adloman]

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

[@nikotttin]

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....

[@mouahrewam]

Very good review ! Cheer man appreciate ❤

[@Voyajer.]

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

[@martinfpv5]

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

[@westwingaero]

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

[@andrewy3711]

This video makes it sound like everybody is flying a cinewoop

[@zfold4702]

@ChrisRosser The test reports mentions Axisflying C204 2004 3500kv motor but the product link you have provided is for 2204. Can you please confirm which one was actually used in tests?

[@RindosRides]

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

[@CorkscrewFPV]

Curious about a 3.5'' freestyle running 6s. I put Xnova T1804 2800kv on my Siren F35 and I already smoked a motor.

[@koinmove]

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?)

[@VincentFPV]

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. :)

[@chrisbee5481]

If 4S try 3000kv amax 2005 motors with HQ 4x3x3V2. Also tested what you did and even more. Also every prop on the market. But Personally I landed on 2200kv 2005 on 6s 650mah

[@VincentFPV]

@@chrisbee5481 I think it's often a personal preference. And mine is a bit strange because I prefer to fly with GF4024 2 -blade props. :D

[@rubberonasphalt]

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

[@cloudripper4926]

They are just known to have a higher fault ratio across products they make. In his previous 3" test he smoked a betafpv motor during the testing.

[@rubberonasphalt]

@@cloudripper4926 thanks man. Glad someone answered a 3 month old question!!

[@MadfishFPV]

What’s right with them 😅

[@JuicySmullietFPV]

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

[@chrisbee5481]

I had the emax 2004 2400kv motors and they were twitching ans runing hot. Tried it on two different builds. Same problem. Even tried them Single just to test. Totally bad. Maybe I was just unlucky, but I'd keep away. Although my emax 2807 and 1404 are still running strong

[@JuicySmullietFPV]

@@chrisbee5481 I’ve run these motors on an AOS3.5 and currently have them on my Quadmula F35s and absolutely LOVE them. My only complaints would be the 1.5mm shaft breaking but then again these are freestyle rigs so there’s obvious abuse on my part. I’m sorry to hear you had a poor experience. Mind has been so pleasant that I even bought their 2807 1300kv motors for my 7” build. Great motors there also!

[@tesaurus_rex5053]

Im running the ecoII 2004 3000kv on my 3" 6s build and it's awesome. Served me well so far

[@nateteator3901]

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?

[@chrisbee5481]

That 2807 spec sheet has wrong data for the amp draw. It makes like 2800g of max thrust and claims to draw only like 38A max. If you compare that to rcinpowers 2809 motor on same prop, then it draws much much more amp for the same thrust. Both motors are rcinpower and it can't be that the aos 2807 perform a miracle efficiency. I work with these thrust charts and just believe me

[@mikybaga9762]

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!

[@runpuppyfpv5744]

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 !

[@ahn_math]

Great video~

[@WilliamRowley-g1c]

What motor should I use for a lightweight ciniwoop? (No go pro )

[@kaygeebee1962]

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

[@Mojohoojo187]

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

[@camdynkellett6782]

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!

[@camdynkellett6782]

Also if anyone has info on where I can find some sort of AM32 discord or support group that would be legendary!! (ps for BF configurator I previously used 10.9 but uninstalled and updated to 10.10 official within the hour of release)

[@chrisbee5481]

​@@camdynkellett6782 my advice you might not want to hear. Just get a new esc. There are good budget ones out there and you save a lot of time and trouble. But you can go through the experience of many hours trying to fix and maybe some crashes due to faulty ESC that costs you more time and money. Ask me how i know

[@camdynkellett6782]

@@chrisbee5481 I appreciate your advice, it's a bummer for me because It was the only option for a 20x20 stack in my country and currently still is. I need a 20x20 for my Shendrones Hydrophobe frame. I've spent enough time now, I'm buying a replacement ESC to see if mine is faulty, and if it solves the probelm I hope that Skystars provides some sort of support, unlikely but we'll see.

[@modquad18]

Strong Work Emax 💪🏽 Probably the least expensive too.

[@donphobos]

Oh!!!! XNOVA even, exciting.

[@lidinprasalrm1027]

GEPRC SPEEDX2 2105.5 2650KV vs Foxeer Datura 2105.5 2650KV Which one is better

[@luis_gbs]

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

[@strykerfpv]

too small, too little torque for that size

[@breakalegfpv9532]

racer star was my first set.

[@dcabecao9357]

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!

[@strykerfpv]

bro, they overheat instantly. unusable for racing and pretty likeley to overheat for freestyle

[@dcabecao9357]

@@strykerfpv I still have a Diatone GTR349 with 1408 motors, perfectly fine for freestyle with ridiculous amounts of power for punch-outs. I'll grant you I never tried racing with it, maybe I should I think it would work fine. Could be a MultiGP qualifying racer would be overheating these and in that case sure, but I have a strong feeling people talk crap about these tall motors for no real reason other than the cream of the crop of pilots need a bit flatter motors

[@richardheedfpv9626]

Agreed

[@richardheedfpv9626]

1408, 1507, 1506, 1606. I hammer all these motors with 3,3.5,4 and 5125 props. I have never had one even look like overheating and they all beat the 2004.

[@volkergoe]

Yes - wide stators are a waste of torque. Overheating is barely an issue unless you f up the tune.

[@Positive_Altitude]

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!

[@theringoffire3228]

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 😢

[@strykerfpv]

not really, people say his motors are only better because he lied about the size but they are only a small amount larger, closer to a 2308 than 2207 and still keep less weight than most 2306 motors, so they really are innovative

[@nateteator3901]

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)

[@strykerfpv]

true, for sub250 you would be better off with something like the tmotor pacer p1604. brotherhobby performs better than the tmotor but the brotherhobby is not durable at all so pick your poison.
