In the midst of installing controls, it's time to set up the flaps. I've never built nor flown a plane with flaps! Each half of this wing will have a servo and torque rod linkage to a 20 inch flap in the center flat section of the polyhedral wing. The ailerons, also about 20 inches long are in the outboard dihedral section. My question is what should the set up maximum delfection be? My guess would be 30 to 45 degrees???? But I really don't have a clue. This picture might help............. Your thoughts, Please?
