I have a Futaba 6XAS, and need some help programming it. What I am after is a way to program my 4 control surface servos, 1 for each aileron and 1 for each stabilator half, so that when I give left aileron, the left stabilator goes up, and right one goes down, just like the ailerons; but when I give up, or down, input, the stabilators move in the appropriate direction in unison. I know someone in this forum has done this before, and probably answered this very question. I just am too inept to find it.

Waiting for your input.
