Can you use the Scorpion 4020 1100 motor on the trex 550? If so how you install it because the motor is wide and does not fit between the frames.

if I am not flying heli I am playing Golf

Yes you can although the 1390kv version is more powerful. You just need to cut a bit of the frame away using a dremel, doing this doesn't affect strength or anything.

60% of the time, it works every time!
