when doing that loop, always have a good amount of elevation or you won't have room for recovery. I used to have this art-tech spitfire too and my friend crashed it, we coulndnt fix the motor mount area anymore cause it's shattered. However, we saved the parts, and only the prop is broken(but spare prop is still unused), but the spinner/motor/electronics/wings and its ailerons/rudder/tail/elevator/wheels/landing gear all are still fine. Also saved the pilot too
