Be warned, I put one on my G&P, V2 mechbox, very stable platform, running an 11.1v 20C LiPo, and it's overheating on most motors after 200 rounds, 40 rounds on a systema magnum.
I highly recommend buying a G&P M120 or M140 and getting it tuned
I haven't had any issues since I tuned my G&P M120 motor
