35MPH?! That doesn't seem right! My tiger 60 touches down WAY slower than that.. And it has a fully semetrical wing. Anyways I think flaperons would be fun on trainer types. You could have a sort of bush plane.. Flaps bigger tires and a bigger engine and voi la perfect bush plane. If you still want to do the flaperons then go to your LHS the owner is bound to have planty I dea's for servo trays or look at other planes servo trays for Idea's.
