I know I've seen a discussion on this in the past, but can't find it. I have a Model Classic IV and the rivets that attach the flaperon horn to the flaperon spar have worked loose. Don't know if the holes have been egged out or it's simply the rivets are worn, but wondering what others have done to correct this issue. I'm planning to drill out the bad rivets and pull the flaperon horn off to inspect. Then replace parts as needed and re-attach. If the holes are egged out, is it acceptable to drill out slightly oversized and use oversized rivets? Thanks!
