I will provide more details when I get a chance to fly it over the weekend. Here is a text explanation.Agreed. Please provide more details.
gimball/imu/compass all calibrated sucessfully, using an expensive high quality level, placed on a perfectly flat and level surface
firmware updated to most recent
mode place in P mode, with all other modes disabled, set to 'follow' mode (not FPV)
take off automatically, and hover to approx 40 meters, look at horizon, not level, pan 180 degrees, horizon not level, gimball up/down, not level,
go into settings and adjust with +/- while in air, horizon levels, yet when exiting menu for +/- the gimbal seems to pop back into overcompensating to opposite slope of horizon. E.g. horizon slopes to left side of ipad display, after 'leveling in app' horizon literally changes to the opposite slope. If left alone, sometimes horizon is level, but any sort of movement or flying sends horizon skewed to left sloping on ipad, or right sloping on ipad. Fly a little bit or pan one way or another and horizon is not level again.
