Problem
A gimbal calibration is performed with one camera orientation and later reused after changing payload distribution, causing horizon drift.
Solution
Root Cause / Diagnostic:
Calibrating gimbal IMU sensors while the camera is balanced with one lens and later swapping accessories or changing zoom focal lengths shifts weight distribution. The resulting payload torque forces the roll motor to work unevenly, introducing gradual horizon tilt.
Actionable Fix:
1. Recalibrate the gimbal on a perfectly flat surface via the companion app's 'Auto-Calibrate' and 'Horizon Balance' menus after every equipment swap.
2. Manually adjust the roll axis offset in the gimbal settings by +0.5 to -1.0 degrees until the camera horizon is true on the digital level.
3. Spin the gimbal 360 degrees and verify the digital horizon bubble remains dead level across all panning vectors.
Pro Tip:
Always perform gimbal mechanical re-balancing before running software motor calibration whenever you change lenses, batteries, or filters.
