Other models

I used to build u-control model airplanes and dogfight them. These where four foot wingspan balsa ribs with silk or a type of heat shrink plastic covering. Powered by a .45 cu in engine that would eat your fingers if you weren't careful. Sixty foot wire leads and you and the opponent would stand back to back in the center of the circle until the fighting commenced. Could do multiple loops, inverted loops and fly upside down. Trick was getting them both in the air and at the same approximate speed. What a blast. You could wreck them and rebuild them and be back in the air the next day.
