[I have a ultra stick arf with a magnum xl 46. I took it out to day for the first flights. Every thing went great , a little up elevator adjustment flew hands off. Get all done , start clean up, pull wing off and notice a burn mark on the dowel, where it goes into the ply on the plane. The hole in the ply started to elongate and burn there also. Whats up with that, and how do I fix it.[>:]
