Hello... I recently got a great deal on a MX 400 that had been sitting in the LHS for a long time and I was wondering if there was a better motor than the one suggested in the manual that is available for this heli or is the motor listed in the manual sufficent for ok 3D. I've been flying helis on the sim for a while now so I thought I would test my skills on a real one. I couldn't pass it up for $70.00....
