I’ve got a tiltwing quadplane that dropped out of the air during flight in QHOVER. I was testing the effects of partially transitioning the wing, and returned the aircraft to QHOVER when it suddenly fell from about 1 meter to the ground. Going over the hardware, there doesn’t seem to be an obvious reason for such power interruption, but reviewing the logs shows a sequence of “RCInput: decoding UNKNOWN” and “RCInput: decoding PX$IO_SBUS” right before the crash. Does anyone know of a reason for such a power interruption? My vehicle is set up as a tricopter in QHOVER, and all motors gave up simultaneously.
