Since the servos and receiver still work it would indicate a problem with the motor and how it was wired. As before, I think you have a short circuit in that wiring. Ususally the Schottky diode is not installed on the motor and is normally included with an ESC for user install. It is easy to see as it is about the size of a 1/2 watt resistor, maybe 3/16" in diameter. If you have a mult-meter you might check continuity in the wiring. For a little more info about the capacitors and the Schottky diode check this site: www.yourzagi.com/motors2.htm#caps or do a search on www.google.com and search 'schottky diode on electric motor' If you have a plug between the ESC and the motor try unplugging the motor and operating it by itself with a couple "D" or "C" batteries to find out if you have a short circuit. And check your soldering around the motor terminals.
