Was the wing saddle a tight fit on yours? I noticed on mine that it was really tight. You might make sure that the wing is sitting down in the saddle properly, and is level (mine wasn't). Overall this kit was really sweet. I have a magnum 61FS in mine and I love the way it sounds. Yesterday I got in 2 great flights, and the park employees where I fly came down to watch. They said, "It even sounds like a real plane!"
