Set Wing type to 2 Ail/2 Flap.
Plug the servos in as shown on the Monitor screen.
Go to Flap System to configure the flap positions for a 3-position switch. One will be to center flaps, one for flaps down, the other for flaps down and to engage the crow mix.
Define the crow mix (any numbered mix, Mix 1 for instance) as FLP > LAL (Flap to Left Aileron, which will give flap-like action on the ailerons). Set the switch to be enabled using your selected flap switch but only in the desired position.
Adjust the mix rate to make the ailerons go up as much as you want. Ailerons will still act as ailerons, but will be deflected up with the stick centered.
Done.
