Rotation
Virtual swashplate rotation. It is required in the following cases:
o The swashplate is physically installed in the model in such a way
that the MAINROTOR-FB servo is not located on the centreline.
o The model rolls (aileron movement) when an elevator control
command is given, and vice versa.
For virtual rotation in the clockwise direction: set negative values
For virtual rotation in the anti-clockwise direction: set positive values
