I had an Avistar that I bashed in pretty good and I figured that I had to take it apart anyway to get my engine and radio gear out. Once I got it apart I realized it wasn't beyond repair so I put it back together and flew it around for quite a while after that. It just depends on what you think you can salvage and what you can turn it into. I've had a few that I just decided I would rather buy a new one and dump the crashed one.......
