It would be great to have the progressive analogue control with the right thumb shifter. I tried to map it in controls with the analogue collective raise and lower but the 360 controller could not assign that axis.

i'm using:
The right trigger as the collective
The left thumb as the Cyclic
The right thumb as the freelook
The RB and LB as the pedals

That setup works perfect with a wired 360 controller.

Figured out how to do this using customizable mode. Not so easy to figure out! Please close this ticket.
