Are you using the dual flap mixing in the wing type? If so, which is what I would recommend, next set up your flight modes in device select. You'll then use the flap rate function to set the flaps, the Flaperon Mix function to complete the reflex or camber, and butterfly to set the spoiler stick (throttle). You would use the aileron to flap mix function to set up the flaps following the ailerons. There is quite a bit of set up information here:
