Bad/loose connection? Pinched wire? Gyro failure? Motor failure?
Both batteries performed without issue. I got in a few flights before it died. Just not even a full day. I was really ready for a day of nice scale flight around the yard. Bummer. Gyro calibration didn't help. Everything on the board is plugged in solidly. Waiting to hear back from Banggood.
