Did you find a resolution to this problem? I put the tilt slider in the middle position, same with the speed slider then tried calibrations with both (pan and tilt) mode switches up, again with pan mode in middle, tilt mode up; again with pan up and tilt down; finally with both up again. In every case, the camera calibrates left and almost straight down. I have had initialization problems which went away on restart. You seem to be the only one with this problem since the new updates, so I hope you can give me some clues.
I believe I read on here that you need to turn the H off and then back on immediately after the gimbal calibration, without doing anything else. Just calibrate...Turn off...Turn back on.
