Last night I was flyimg my AXE CP for about 3 minutes in a nice steady hover. Suddenly the trottle jumped with no input for the stick to almost full power then back down and then up and repeat. I couldn't get it to the ground smoothly beauase of the lack of throttle control. Ended up bending the feathering spindal (for the 4th time...) and stripping the large gear on the main rotor assy.

Any one else have this happen and what could be the problem? Rx? Tx? Motor? Battery(1320mAH lipo)?
Also any one know of a better main rotor gear?

Thanks
