The PA-11 is a high-wing braced cabin monoplane with a tail-wheel landing gear. The enclosed cabin has two tandem seats. Early PA-11s had a Continental A65-8 engine, while the later ones had the option of a Continental C90-8. The PA-11 was based on the earlier J-3, but with a cowled engine, with the windshield sloped at a shallower angle; the engine cowling fully enclosed (as on the earlier J-5), and the fuel tank placed in the port wing root. Both seats were slightly moved back, and solo flying was usually from the front seat. The prototype and two subsequent pre-production models were built using a modified J-3 fuselage and wings. The prototype first flew in August 1946 followed by the two pre-production aircraft later in 1946. The first production aircraft was completed at Lock Haven in March 1947 and production continued at Lock Haven until September 1949. A second production line was established at Ponca City between September 1947 and January 1948. On the early PA-11s, the fuselage was painted with a metallic blue on the lower half the rest being Lock Haven Yellow. The later PA-11s were all yellow with a simple brown stripe. The PA-11 also formed the basis for the next evolution in the Cub series, the PA-18 Super Cub, which shares many features.
