Last few times flying my propprop nut has come loose. I’ve tightened it and also had others tighten it to be sure it was as tight as it could get, but it keeps coming loose. Even have a locknut on it. It’s a four stroke, and I’ve been told it’s because of the kickback. I don’t really care why, I just want it to stay tight. One suggestion was to get an aluminum spinner & plate, and that next on my list things to try. Is there any reason I don’t just give the nut and prop some ca or epoxy ? I know it’ll be tough to remove, but that’s the point. Any ideas or suggestions. Thanks
