No #2 Developed from the 1930 Taylor E-2 Cub by Piper, which bought the bankrupt company's assets, the two-seat Piper J-3 Cub taildragger became the primary trainer of the U.S. Civilian Pilot Training Program and four-fifths of all U.S. military pilots in the Second World War received their initial flight training in the type. More than 19,000 had been built by the time Piper ended production in 1947 in favor of the PA-11, a developed version that sold some 1,500 examples. A related and popular member of the family was the PA-12 Super Cruiser. The PA-11 gave way to the PA-18-95 Super Cub, which Piper introduced in 1949 and eventually stopped making in 1981. However, other companies subsequently have produced kits or plans for Super Cubs and more than 9,000 have been produced. One of the most popular light-aircraft families of all time, the Piper Cub/Super Cub family is revered for its wonderful short-takeoff-and-landing capabilities.
