Cutting down motor winds....

[captain harlock]

I have my very first brushless system which is the kontronik fun480-42 and I've cut the winding of that motor without noticing any abnormal reaction from the motor. I think the enamel you're talking about is the same thing used on the Mamba Max controller soldered wires?
If so, I think it's very easy to make a strong and perfect joint without any trouble.
