Set at 0 for horizontal & YawHave you checked to see that there isn't already an adjustment applied to it? There shouldn't be but accidental and or unitended changes can be made.
I've seen that on a couple of DJI drones. Running the gimbal calibration routine with the drone placed on a flat surface took care of it in both cases.3rd day out and I see a slant on my horizon
Is it a normal thing that most people adjust?
Tends to do it on all my drones of they didn't take off from a level surface.
