I'm about to try flying my new composite Kangaroo. I like how they do the hinges by cutting the skin on one side. The question I have is that the top skin which is cut on the elevons has a slight upward curl. When I straingen it out there seems to be a big potential for the wing skins to bind up and cause a loss of control condition.

Has anyone experienced this if so what did you do about it.
Thanks
