Very informative. My new motor had those bumps you referred to. I thought the motor was garbage but now I know better...thank you.

Really informative and appreciate the time it took you to post this.

Thanks good job. To check the kV I usually go with a cheap speed controller without timing and measure the RPM at a given voltage (but i admit not everyone has an rpm meter at home)

Thanks, mate. Very valuable video. 👌🏻

Nice been waiting for this

This is fantastic. You definitely earned a subscriber! What is the website you used to enter those values?

A few years ago, I got a hubsan h501a drone, and after about a year one of the motors stopped working and created a bit of smoke. At the time, I was planning on spending some money on a dji mavic air, so I took that as a chance to get one and never looked back. The hubsan kinda got abandoned in my closet. Now a couple of years later I'm thinking of fixing up the old drone just to fly for fun when I'm not flying my mavic. I know that it's the motor and not the esc because I tried swapping two motors around and the a different motor worked fine on the esc that the fried motor was on. I'm just wondering if it's at all possible to repair the motor, or do I definitely have to buy a new motor? Thanks 👍

My brushless motor by castle creations which I have I noticed I run it off the rc and see powder black stuff shooting on the table and is that a indicator of damage? I'm hoping it's the pinion gear that is stripped and made the dust stuff.

Can A Overhead Brushless Motor, Fry Your ESC Or Short It Out?

My motor doesn’t spin freely. I believe when I opened it up it was a crack in the magnets an the shaft has play forward an back can I fix this if so how ?

Great, the video I was waiting for, How about measuring the resistance of the 3 phases. will it help identify any problem ?

what if the cogging feels much stronger on my brand new Trinity 4.5 t and even stronger on my Dash 7.5 t but very weak cogging on my Trinity Kill Shot 13.5 t ??

I damaged a drone motor magnet by getting it stuck on a branch, i could feel the difference in cogging.

I don't know who to pass this on to, but there's almost no videos about vent holes in rc bodies. I want to know the aerodynamic effect and cooling performance that can be achieved with a few well placed holes for nitro and electric RC vehicles. Especially SCT bodies

My rotor opened and locked the motor. Not sure what they use to wrap the rotor but it didn't work lol Poseidon 2200kv. Great info vid Thanks💯🙂

My electric scooter motor is just juddering when I apply throttle,vibrates alot and doesn't move forward,any idea what the problem is ?

I have a brushless motor that only spins when I’m holding the motor in my hand. But when I install it, it hums but doesn’t spin the wheels

My brushless motor in my stadium 1/10th scale truck only has half the top speed it used to but still has the same punch 👊 whats going on?

Hi, so i want to ask, Im going to get a goolrc 3400kv brushless motor, i think its max 105 a, also an 125a goolrc esc, and a 3000mah 35c (105a)lipo, Do you think it will be good to work?

great vid ryan! hows your jaw?

red blue blue yellow red yellow you said it kind of fast

talk too much

Good information. Please can you cut out the excess words like "The next thing you wanna do is you wanna go ahead and..". These are time wasting and irritating.
