The Piper J-3 Cub was a trainer / light aircraft designed and manufactured by Piper Aircraft from 1938 to 1947. It was the most-produced model of the company with almost twenty thousand built in the United States.
In 1930, the Taylor E-2 Cub first emerged when William T. Piper, a Bradford businessman asked Gilbert Taylor of the airplane manufacturer Taylor Aircraft to build an economical, easy-to-fly trainer that a normal person could bear to rent. Piper bought a $761 controlling share in the manufacturing company when it went bankrupt and kept Taylor as the president.
In 1936, the Piper J-2 Cub was built from a modification of an earlier Cub. Afterward, the J-3 Cub emerged as a further development of the previous J-2. The modifications included the vertical stabilizer being integrated into the fuselage and enveloped it at the same time with every side of the fuselage.
