I cut the ailerons out and guess what--the wing has already been rehinged! I couldn't figure out why one cut was taking so long, then I realized I was cutting through a hinge that had already been cut off (so I couldn't see it when I looked through the gap)--and it was the plastic with a fixed brass pin kind. Other than that, it went smoothly. The cuts are pretty good, and the CA hinges came off quite easily. Unfortunately, the hinges weren't at the same locations on each wing, so to get the amount of flap/aileron I wanted I had to cut in the middle of the actual hinge on one side, so now one of the flaps is still completely hinged, but the other needs another outboard hinge.
