James,
Michael did something like that at Brodak's a few years ago but we had the extra pleasure of the fuselage being broken as well. Actually it was not him flying into the ground, but an engine giving up part way through a maneuver. Thanks to the proximity of the Brodak Hobby Shop and the use of John's shop we got the rebuild, recovering, test flights and wing tweaking done by that afternoon so that he could keep on flying. Keep up the good work with your son and I hope to hear that his name gets on the Junior trophy in the near future.
John
