I bought an align Trex 300x just before Christmas and have been doing some great flying. Just over a week ago I was practicing inverted flight and crashed from about 3' off the ground. (lost orientation) I repaired all the mechanical aspects of the the heli, but when I went to test fly last night, the helicopter won't hold stable and the throttle pulses down randomly. I don't know if the mini flybarless controller is damaged or what it could be. Align's troubleshooting doesn't have any resolve for this. Any ideas would be great.
