WedJ - If I paint the wing, the aileron's will be attached. After primer 1 & 2, and a lot of sanding. You can put a small dab of vaseline at the hinge points. After finish coats on wing and wet sanding, make a block sander out of piece of hardwood. About 1" X 1" X 2". Use this to get the angle between the tapered LE of the aileron and the TE of the wing. It may seem a little stiff right after all paint drys, but it will be fine, wet sand final coats. You can get a #11 in there and clean up a little. A tiny bit of thinner on a modified cotton swab can help. These strip aileron's will have their own servo's, two channel's, but not necessary.
If you MK the wing and ailerons, make the film into a V, crease it. Set in, use point of iron, detail iron or 20th Century iron is best, if it is still being manufactured. Set in, iron to finish, 250-275 degrees, or your choice. You can easily cut separation of limit lines with a single edge razor, use finger adjustment, faster cut, smoother line. Few more pictures here of hinging, stationary sander for getting the aileron's angle right for section in next to fuselage. The aileron's will be finished to like new, vs. what these pictures represent at this time. Attached wing from another plane was done with MK and ailerons attached. When MK a wing like this, it is best to paint the wingtips, match paint up. MK will adhere on the color paint line. You can wrap and seal the MK easy on the tips, just takes time, stretch down and seal.
