I purchased a KDE motor for my trex 550 so I am going to sell my 730mx. I have about 30-40 flight on this motor. So its still in new condition. The heli has never been crashed so the motor has never been stalled or over heated. I purchased this with my align 550 pro dfc kit. So while I cant give the receipt up I will help anyone with warranty repairs if it was to ever come to that. $100 shipped comes with 16T pinion
