Yesterday I took the Mavic out to do a range test - 2 3000mah LiHVs attached with 3M Dual Lock.
I started flying and quite quickly the aircraft started wanting to turn right with no stick input. No IMU or compass errors.
I thought perhaps a battery had come loose, flew back and had a look - no issues.
So I flew out 6,000 feet or so (empty farmland), got tired of all the swerving, and hit RTH. I got not much higher than 200' at any point.
The craft flew straight as an arrow back to my position.
I uploaded the flight to Airdata, and there were a couple of oddities - Mode changed to GPS Atti (Atti mode, right?), mode changed to Wi-Fi Reconnect, then a meter later changed back to GPS Atti. I also had a couple of instances of Downlink data connection lost - both at close distances (4 meters for 7.9 seconds and 266 meters for 1.2 seconds).
There were plenty of satellites available (14-18 through the flight) and Kp index very low.
Is there any way I can figure out what the issue was?
Can the craft fly if the main battery shuts off (say the main battery had less voltage than the aux. batteries)? It was very bright and hard to make sure the main batt. was on.
Any opinions or suggestions would be appreciated.
