My last crash with my Great Planes 300 extra was due to pilot error during a high speed low pass....result was a wing kit and cowling.
The one before that with the exact same kind of plane was some mysterious radio malfunction. I know, they all blame that. This was during its maiden flight. I had just taken off and was doing a very gentle right turn when it rolled all by itself and came back to level flight for a couple seconds. Then it did it again and came back to level flight again. The last time it rolled it went nose down and augured into oblivion. On the way home from the field I stopped at the hobby shop and got another arf of the same plane. It really flew nice for that quarter circle around the field!
