Operating with a dual gimbal and an H20T "mounted port 1 side". We noticed that the camera yaw indicator on the controller was approximately 3 to 5 degrees to the left of the aircraft nose position indicator. The camera postion is slighty to the left as well. We have calibrated the gimbal numerous times to align the two indicators and the camera position. When we pan the camera down it seems to return the camera and indicator to the left 3 to 5 degrees. Is there a camera pan or yaw position indicator or something else that could be the issue?
