When you go into the camber mix, you have to press the knob of the cursor joystick to go to the second page of the camber mix AFR. You adjust how much aileron droop you get and then how much elevator compensation you get. You can adjust how fast the camber changes in the CAMBER AFR section. You also press the joystick switch to get to the second page.

If you have flaps, too, then set up a mix with camber as master and flaps as slave. Now, when you activate camber, the flaps will deflect. You can use NULL as the flap control, unless you want to have the flaps operate independently of the ailerons when you add them.
