Hi guys. This is my first post. I had a strange experience a few days ago. I recently installed copter 3.4.3 and had a few great flights. It felt nice and smooth and stable. But a few days ago I lost Yaw control and had a hard landing. About my setup:
Arris M680 Hexacopter
13 inch Props
Sony nex gimbal
Pixhawk 3.4.3
Gens Ace 6s 5000mah
433 Telemetry
5.8ghz video link
2.4 Radio ReceiverA few days ago I went for a flight. Everything went fine for the first 6 minutes. I came in to land, disconnected the battery, adjusted the gimbal and then took off again with the same battery (still had enough voltage to fly and enough for emergency..) I flew in stabilize. I hovered for about 30 seconds and all of a sudden it yawed about 90 degrees clockwise. I tried to correct but it did not want to respond properly. My Pitch and Roll worked fine but I could not Yaw. I assessed the situation and the best thing to do was choose the softest looking bush.. Luckily no damage as I kept a low altitude.
Can anyone guide me as to what went wrong?

I noticed that the Euler Yaw look strange to me..
