What was always missing from this undocumented feature on the M2 was a similar horizontal scale, like the vertical scale for gimbal elevation, which has a zero mark and a degrees left and right. On the
MA2 when you activate the touch drag capability, and drag left or right,
the desired horizontal scale suddenly appears! Now you can drag it back to center, without screwing up the continuous video by pointing the camera straight down and then back up, which was the only reset mechanism on the M2. The only problem I have had with it is that It has smoothing included, that makes it almost impossible to get it back to zero. It constantly goes back to -1°, which will make it fly crooked. Flipping the camera down and back up no longer restores it to zero! I finally managed to get it back to zero once, so I am leaving it there, as I have no confidence of being able to get it back to zero again! Same problem as before, but no simple fix! Could just be a unique bug on my unit.
