Thanks for the advice. I believe I have built the ailerons according to the plans and have added additional material for the CA hinges (1/4x1/4x 1.5 inch blocks) both on the aileron leading edge and the wing trailing edge. The plans call for hinging in the middle of the aileron but I am open to modifications or using robart hinges if that is best. I am guessing that if I add material to bevel I would need to add either thick tri stock or at least 1/4" balsa plank and then bevel to get a 1 inch deflection. I have never used a top hinge but am open to suggestions.
