About 18 years ago, the Tulsa Gluedobbers controline Club had a Freestyle Stunt event that was held for 3 or 4 years. The Saint Louis club, the Lafayette Escadrille, held a Freestyle Stunt event also during the same time.
the first year we had it, the rules were simple; The time limit was 4 minutes, and you could do any manuever you wanted. The flight was scored from 0 to 100 points. The judging was done by a den of Cub Scouts. The contest was won by a fast combat ship that wowed the scouts, and crashed. The Cubs gave the Combat ship the winning score. After that we changed the rules so that if you crashed, you were DQ'd
After 4 years, the entries were down to 2 people, and we cancelled the event.
Freestyle stunt was the first of the stunt events back in the day. The stunt pattern came later. George Aldrich used to tell stories about Freestyle Stunt events held in football stadiums that had many spectators. The winner was the flyer who had the loudest applause from the stands..
