So when I have my gimbal roll at 0.0 my camera is completely sideways. I have adjust the gimbal roll to 4.8 for it to be level but it used to be at 3.8. I feel it keep tilting farther and farther even after gimbal calibration. After I go to 0.0 and calibrate it's straight right after it finishes then immediately turns slanted. Anyone else having this problem or know a fix for it?
