Four team members participated in this review. @h-elsner, @Steve Carr, @DoomMeister, and myself. I thank the other team members for their support. This is the result of the flight review:
The event was not triggered by a motor loss. Everything that happened during the flight, and everything changed by the crash, was the result of a bad battery. The #5 motor failed at contact with the ground, not in flight. We would recommend:
1.) Dispose of the defective battery.
2.) Ensure the GPS Module (GPS/Compass/Altimeter) and the associated connector are properly mounted and properly connected.
3.) Ensure the control Pots are clean and functioning properly.
4.) WHEN the control Pots are clean, perform a new Controller Calibration. (not before pots are clean)
5.) Ensure a fresh accelerometer calibration is performed.
6.) Ensure a new Compass Calibration is performed in an open area.
7.) Remove camera for test flight.
8.) Perform some test flights.
There's no way to get information about the defective battery. I have 2 that just started to not hold power, a newer 8050. Any way to get the serial number from the data (sorry, that might be a stupid question).
Second, I keep getting mixed answers... The rapid flashing blue lights at startup, is that normal? Up until now I had never had that happen. Are the blue lights an indication of an error?
