Yeah, I've lost several wheels, mufflers ect. before I learned to loctite everything. I spent an hour Sunday roaming the field looking for a guys back half of a muffler, prop and spinner. I found that anything that can fall off will. Too bad there's nothing to do about oil soaked wood - my GP Big Stick 40 had 1000 plus flights on it. I was doing some rolls when I saw something big fall off. Plane seemed to be flying OK. Brought it around and the whole main gear (mounting block and all was gone). I was able to land soft and everything was fine. The block was too oil soaked to glue back on, so I strapped it on with aluminum straps and nylon bolts.
