Pixhawk 2.4.8, Plane 4.1 dev.
Accel calibration successful for all axises.
Auto-tune not performed yet (did not fly yet).
Plane: 2.4M foamie glider.
During control surfaces response check in Stabilize mode, when pointing the nose up the elevator goes Up instead of down and vise versa, when pointing the nose down the Elevator goes Down.
Roll response is normal.
Would be happy to know the possible reasons for this behavior and possible ways for correction.
