RE: recovering a wing - ailerons?
Yea, The World Models Skyraider hinges are tin with pins.
I'm guessing that the Mk I has a single aileron servo (the Mk II does). TWM does not glue the aileron torque rods into the ailerons - they simply drill a hole in the balsa and then insert the rod. After a while balsa will deteriorate resulting in aileron slop and in extreme cases pokes out of the covering. You should take the opportunity to cut the hinges, recover, use CA hinges (easy to install) and use epoxy in the holes for the torque rods. Before you do make sure that the exposed wire is clean and then rough it up with some 80 grit.
Good luck ...
