Cheapest solution to the rattly wing, go down to any stationary/craft/hobby shop and buy a small sheet of card foam, it is about 3mm thick, cut out a strip, double sided tape to the underside of the wing, covering the holes. Does two things, bridges the gap to stop it rattling and also stops the wing mount from scrathing the paint off to.
Chris, hope your not classing me in the same bracket as the American bafoon
