Added flaperons to my Altech Pilatus Porter which has a 6' span, full length ailerons 1 1/4" wide, straight wing 10" chord. The flaperons make almost no discernable difference in slowing. It's a semi-symetrical wing. I am thinking about bolting on some 'extensions' about a foot wide to the bottom of the aileron and extending the 'flaps' portion an inch or so to actually give some functionality to the flaps. What do you think, would it work? Would it have any negative response on the aileron function. I am using a Futaba PA1 which does a great job of wing leveling.
