First of all I opened the motor to take a look noticing protective isolation layer on the copper were melted. Not so strange, because when I approaced the motor after the plane fell from the sky, it was insane hot.

Before removing all wire I measured the wire diameter to 0,30mm. I found this king of wire inside very small tranformators in a computer power supply.

By using this picutre, found on this page. I was able to re wound the motor.

I actually did wound all the poles at the same time, well, one by one, but all three wires were in use, if you follow.

After finish wounding I had to connect wires together to make only three wires, brushless motor has three out wires.

Since it`s a pretty fast motor I made a delta hookup, but I did a mistake at first. This motor should have around 195mOhm per 14-turn, maybe I did not mention it is a 14-turn motor. Which means each pole (there are nine here) needs 14 turns of isolated copper wire and in a small motor like this one, it`s not that easy. Anyway, by hooking up wrong end`s I broke a ESC of mine ($10) so I had to buy another one.

The motor works just great now and I might add a video later.

Fixing brushless motor

I solved the weiring problem by mounting those wires to the servo-mount-hole. I had to a neat trick with the input-cables as well. Did use three extenders which are used in desktop computers, to mount the mainboard to chassi. Should be viewable in my gallery below.
