I bought this gimbal last March. It's never really been exposed to cold weather. Today decided to do a flight and see the bare trees with ice and snow on them. Temp is below freezing. I powered the gimbal up inside in a warm area. It set its level and pitch. I go outside to fly and after a minute or so, the camera was pitched up and level was off. I landed and repowered gimbal and it was ok from then on during the next flight. Was it the sudden temp change. I have never seen this before.
