If your hingesare glued into the wing at this point, you can cut a piece of koverall just large enough to cover the trailing edge verticalsurface. Cut slits in thekoverall to allow the hinges to protrude, and dope the koverall down. Trim it before covering the top and bottom of the wing. Your fabric covering on the top and bottom of thewing can overlap the trailingedge fabric that is doped down.
