Continuing on from previous report - More details about the issue:
UH1 sits on the ground at a different angle when using AFM, compared to Standard flight model:
Notice pitch angles.
On the top picture, with AFM enabled, you can see the UH1 keeps a nose-flat-on-horizon attitude when landed. This is incorrect and you may also note that the front of the skids are partially clipping under the ground.
On The bottom picture, with AFM disabled, the UH1 lands with the correct 5º-ish nose up attitude. The skids are not clipping, as they are perfectly aligned with the ground surface.
You can observe also, by toggling AFM on and off, that the aircraft will teeter-totter back and forth between these two different positions. These changes are immediate when going from AFM to Standard mode, and take about 1~2 seconds to revert when switching from Standard to AFM
