So it doesn't mater what the angle is between the hinge line and the end of flap/aileron as long as they are parallel to each other and the hinge lines are parallel. It is easier to make the ends of the flap/hinges parallel to the centerline of the plane. I also doubt that variation in the flap aileron size (as long as they are the same on each side) would make much difference since you can't tell what size is supposed to be from the builders manual. To make my hinge lines parallel I made my ailerons slightly larger. For you guys that are at this stage don't forget that the wingtip rib is at some odd angle and not perpendicular to the main spar, but the ends of the ailerons should be parallel. Just fill in the wingtip with foam and cover it with one bid to make it parallel to the end of the aileron. The aft spar is not given any position in the manual=don't forget to leave room for the counterbalances. Bill N7WB
