That is the part that is scaring me about this build Joel, I may just use some mixing in the radio it will be easyer in two ways, I will not have to hook up the linkage to the canard everytime I put the wing on, and I won't have to build a sliding tray. I see that dubro sells a mechanical mixer for this purpose and I may use one of these when I build a crusader(RCM).
