Comment:
Built in 1947, the 1-21 won the Nationals that year flown by Dick Comey, whose 483 km./ 300 miles flight was a National distance record at the time. There was no market at the 1947 price so a simpler model, the 1-23, was produced instead. Stan Smith flew a 1-21 in the 1952 World Championships at Madrid οΎ– Cuatro Vientos in Spain. The ship features triple spoilers (2 on top, 1 on bottom) and water ballast tank in the wing.
