AAAARRRRGGGGHHH !!!!!!!!!!Soldering prob. - RC-Monster Forums

Typical motor wires are simply the extensions of the coil wires and so have an insulating varnish coating on them. Makers leave the last ~1/2" unvarnished to solder, but if you cut that off, you are gonna have a heck of a time soldering to them. You will need some kind of solution to dissolve the varnish off the ends. Just be careful to keep the solution from wicking up into the motor, because if that happens, the only thing it would be good for is a refrigerator magnet.

Brian my understanding is if you cut those wires coming out of the motor ( stiff wires) . That it affects the way the motor runs .

That can be true. Remember, motor wires are comprised of multiple strands of wires, each with that coating. If the varnish is not removed from every one of them, the motor will run very poorly or not at all. So, even though the strands on the outside wires look good, the inner strands can still be coated. Not only is running a motor in this condition bad for the motor, but it also can draw HUGE amounts of current from the ESC and can kill it.

VERY VERY good to know. Thanks for the info.

What motor were you working on? Brand/size/kv?
