I have a bvm f16 and as you may know, the ailerons also work as flaps for landing.
I would like to set my Mercury to Assist mode for aileron. Here is the problem: when I turn the unit on, it reads the zero with ailerons in normal position. For landing, the ailerons go down as flaps and therefore are off zero and the giro automatically goes to rate mode.
A possible solution is to turn the unit on with one aileron in flying position (lets say the right wing) and the other in flap position (lets say the left wing). The Mercury has separate giro functions for aileron A and aileron B and therefore the zero would be set separately for each aileron
Right aileron would be in assist mode when flying, left would be in rate mode (or off). When landing, the left aileron woukd be in assist mode, the right in rate mode (or off)
