I own the same motor, and have yet to get it to work. I soldered a .1 microfarad cap from (-) to (+), one from (-) to can, and one from (+) to can, and the motor glitches like MAD! I can't even make one lap around a track with it. Its brand new, no wear, perfectly true, perfectly seated brushes, perfectly oiled and centered, and the motor runs like CRAP. I have no problems with any of the 6 or7 other motors I own (p2k2s and monster pros).
Integy refuses to take it back.
