I have/had two hog bipes that I use flaperons with. I use my flap dial to move all four ailerons up or down depending on what I want to do with it. Mostly move them around for 3D style flying.

I move all the ailerons way up if I want to do an elevator or only slightly up if i want to fly a harrier pass at a high angle of attack.

I move them down if I want to use them like flaps for a slower landing or for very slow forward flight in a slight breeze. I have found that the Hog Bipe will have a harder stall break with the flaps down and only goes a little slower with them down.

To make loops tighter, I programmed in up into all four ailerons with up elevator. If you give down aileron with up elevator, the loop is not as tight since the nose down pitch change with flaps fights against the up elevator.

Flaperons are fun to play with now and then, but I found that most flights I will just leave them neutral and have fun. I actually end up moving all ailerons up more than down as flaps. Have fun experimenting.
