I gave Randy a call. He had pretty much done everything most would think of doing. This copter was previosly flying great, until a recent crash caused by a prop failure in flight (Approx 10ft off the ground). Lipo is a 4S Thunder power and was fully charged. He has his voltage warning set at 14.8 for first level (with .30 loss), and 14.3 for red level. The 4S lipo is selected and showing full voltage in assistant. We tried to disable voltage warning, and that did not help either. The LED still flashes red rapidly, and IMU-OFF shows in Naza assistant. He tried to reset the model to default settings, still no luck. All connections were checked/double checked. Solder joints on BEC are good. Motor wires and ESC connections all seem to be good.
Does anyone else have any other suggestions? We tried to troubleshoot as much as possible, but still got nowhere. Is it possible the Naza was damaged in the crash? Any advise for this guy would be appreciated.
