1515 2200kv heat issues in buggy

I just read the whole thread, and it sounds like your motor was bad from the start. A shorted winding in a motor WILL cause short runtimes/hot components/cogging no matter what your gearing/voltage/ESC settings. A bad ESC could have the same effect, but I think if it were the ESC you would've seen smoke by now.

Edit- Hmm actually you did say you tried another motor/ESC right? Is it possible they might be bad, too?
