After flying my P2v since they first came out I have flown many many times. This morning, nothing having changed from a few days ago, in the field, and after doing the compass dance and establishing >6 GPS Loc, (9 according the the telemetry, I commanded motor start. Nothing, nada zip. Home, I plugged into assistant and everything seems ok. Recalibrated sticks, IMU ect all values are exactly mid range where they should be. But still no joy when commanding motor start. Short of somebody building an airport out in the countryside, anybody got any words of wisdom? Oh, and the Vision has never been crashed.
