🎦 V#50 Part 2 - 3650 Sensorless Brushless Motors - Maximum RPM Test & Comparison

[@RcModwerks23]

*****Watch Part 1 here : www.youtube.com/watch?v=db6Zm...​ This is another test and comparison of the highest RPM ( Revolutions Per Minute ) we can get from six 3650 size brushless motors with different KV ratings. Feel free to tell us which of these motors you have in your rc car, and also share us your experience with that motor .

[@troydoherty2738]

Awesome video, thought about testing the same kv but seeing which one draws least current and what temperature they reach?? Keep up the great work!!

[@RcModwerks23]

Thanks! I didn´t get those info because I was only focusing on my speed run builds at the moment ( I was more interested in knowing the motor max RPMs) ... those info will be useful if you run the rc car in the track 👍

[@bigbeardrc4145]

Really really well done mate.really interesting and eye opening

[@RcModwerks23]

Thanks! but this is just an RPM test wihout load, and each motor might perform differently under load.

[@TheRCMaster]

Awesome comparison and tests 👌 great video bro 👏

[@RcModwerks23]

thanks bro! 👍

[@operator8014]

Hey, I always wonder how these hobby grade motors compare to the performance of the brushless motors on cordless power tools.

[@RcModwerks23]

IMHO the motors they used in power tools are slower but they have more torque, but we cannot make a conclusion unless somebody makes a direct comparison. Thanks for watching !

[@tyronewilliams3698]

Hey. I always watch your videos. I brought (2) EAT 14, after watching your videos. I LOVE WHEN YOU DO YOUR RC RUNS. VERY NICE AND SUPER FAST! I would like to upgrade my cars. What is a good powerful motor and ESC combo that will fit my car? Do you repair RC cars?

[@mark.a.estrecho]

This is a great comparison! Thank you for making this video! May I ask, can I use a 3S LiPo battery on a 80A Brushless ESC?

[@RcModwerks23]

Yes you can, as long as the ESC is rated for 2s-3s lipo

[@DennisLowery-r4b]

Been using that 4370kv f540 in my traxxas Bigfoot truck. Working awesome so far. If all goes well I'm gonna order 2 more for my rustler an stampede. I might get a fan for it though.

[@RcModwerks23]

Good that it´s working well for you. You can also try the 3650 size motor even if it´s the same kv, it will give yuo more torque compared to the F540.

[@Speedslays]

@@RcModwerks23 yes I'll probably have to change gearing for 4x4 Motor gets pretty warm.

[@Grantvanl]

What's the top speed and would you recommend it for a rustler 4x4?

[@Speedslays]

@@Grantvanl I thunk it was like 40kmh with the high speed gearing for a 2wd stampede. But I put it in my 4x4 pede and it wasn't as fast. So not sure if I'd personally put it in anything 4x4 long term

[@RcModwerks23]

Get the ones with lower kv ( 3600-4200 kv ) and it will be good for street driving... the equivalent of the stock 550 motor is aorund 2800 kv only.

Thank you for this nice video! Which motor would you recommend for speedrunning a wltoys 144001 on stock gearing with 3s lipo? I'm currently using a 3650 3300kv motor with a top speed around 100km/h, my next goal is 120km/h.

[@RcModwerks23]

If your speed goal is 120 km/h in 3s lipo, either the 4300 kv or 4500 kv can do the job. Thanks for watching!

[@ValFPV]

@@RcModwerks23 thanks for your answer! Do you think 5200kv would give me even more speed or would it have too little torque then?

[@aizatnorman]

Do you have any idea if all of these can run smoothly on a surpass hobby 60a ESC? I don't trust that 120a budget blue ESC. Cogging on those things can be felt more significantly too.

[@RcModwerks23]

I can´t tell because I dont own that specific ESC ... but all these motors will pull 60+ Max Amps. If you want a smooth system, better get a Sensored motor & ESC.

I have a wltoys 124019 which one fits the stock motor mount and I wanted to get the 5200kv silver one but people say you lose acceleration deos it lose to much or not my goal is 95 km

[@RcModwerks23]

All of these 3650 brushless motors are direct fit to 124019 ... the selection of motor kv depends on how and where you drive your rc car . If you want speed and drive on-road only then the 5200 kv is Ok ... it can hit 120+ km/h on 2s and 140+ km/h on 3s. But if drive off-road better get a lower kv motor. Check my other videos and see the kv I use and top speed I get with them. The 4500 kv got me 120+ km/h on 3s at 3/4 throttle.

[@norcalrc]

[@cds1223]

I just blew up my 60amp esc with the 4300 kv on 3s surpass platinum combo. About the 3rd run but it was a 4x4 MT. I only ran it because thats what was in the combo and awaiting my 120 amp. :/. Sorry. Be careful.

[@RcModwerks23]

Yes, there will be no issue for the 4300 kv motor to run on 3s since it will only be around 47k RPM (which is not yet exceeding the 50k Max RPM recommended by most manufacturers).The more sensitive piece is the ESC, so just make sure that you will get a good one and 2s-3s capable. I don´t own a Platinum series ESC so I can´t comment about it. Thanks for watching my videos! 👍

[@RcModwerks23]

@CDS ....Yes, we should always be careful with the ESC (personally I always check the Temps) because it is the part which usually fails instead of the motor. The cheaper brands generally are more prone to getting burned when abused or misused, but I also saw many expensive one like Castle Mamba ESCs that also get smoked. So, as you said, be careful.

I think that due to my ignorance I should have bought a 4500kv motor (max amps 75A). Thank you for your help in advance.

[@RcModwerks23]

Thanks ! I dont have that specific ESC, but it sshould be OK since I was also using a Hobbywing 80A ESC with my 7700kv motor without any issues. The motor will easily get hot due to the high kv, so you only need to watch the ESC & motor temps. 👍
