I think it would help a lot of individuals having gimbal level problems if we knew how the gimbal calculates its position on each axis. I am not at all familiar with how it works, so I ask if anyone out there knows how these things work? Do they interface with any of the copter components like the IMU to calculate level? Does it use the copters gyro outputs to counter the movements? Or any other components? Who knows.....maybe the shadow knows.
