Hi! I will be telling you how to make ur own diy brushless motor it simple, u see here in nigeria brushless motor cost up 4600naira, and I u want to make rc helicopter or quadcopter even plane, and u need and adjustment for ur money , here is a way out , making any kv on ur own following the prosidior or steps u will lern how to make you own.

I got this motor from a vedio shop lie in helplessly on the group, I open it and remove the circuit in it, behold the amiture is 24 but it was flat, I remove the coil on it.

step 1 romov the coil
I remove the previous coil and replace it with a thicker one, buy a now copper coil in the market.

step 3: coilling get the thick copper wire and recoil it this way in the image show .

my is 47 turn calculate it by the amiture.
note: who ever that is making this project is on risk, u have to be cearfull when test.
Note: this project will save ur money and it can fly any kind of robot u made with it.

step 4: solder wire
Solder wire on it, each represent something, A B C A is airmitter b base c collector, A and C is ur +& - b is ur signal , but don't be confuse any one can serve as abc.

step 5; stand holder
I carve aluminum in a round shape, having cross on there side were u can house ur nuts.

step 7 : install it
Install it under the amiture, the motor have long not loss it and tighte it when u have install the aluminum stand hold .

step 8: glue back the brushless I replace the shaft to be long, I glue it back with Eposy gum.

step 9 cover it and add some thing at the end shaft not to fall of when spinning.

step 10 making sure the body are not tuching the amiture. U are good to go.

step 11 test
I test it with 30a esc my motor is 1000kv .
When testing first plue ur esc to motor and esc to servo test were u can throttle it, then fix the battery make sure that the servo test is not in the middle pleas it will be at 0, wait for the beep sound to finish then u start throttling. Waw the speed is amazing ...........
