The 32 bit board with 2 IMUs holds its level quite well, but still sometimes it gets confused and the horizon rolls momentarily. I was thinking, in my case the same SBUS that is connected to FC is connected to gimbal to control the tilt. The SBUS provides also the stick commands to FC, and they would be available for the BaseCam board also.

Would there be any idea to read the stick commands, when they are centred for longer time, trust more ACC and when they are not centred trust more gyro?
