Piper PA-18 Super Cub

The Piper PA-18 Super Cub is a two-seat, single-engine monoplane. Introduced in 1949 by Piper Aircraft, it was developed from the PA-11 Cub Special, and traces its lineage back through the J-3 Cub to the Taylor E-2 Cub of the 1930s. In close to 40 years of production, over 10,000 were built. Super Cubs are commonly found in roles such as bush flying, banner towing and glider towing.
