“America’s Favorite Light Plane”

The yellow Piper J-3 Cub is one of aviation’s genuine classics. More than 20,000 Cubs were built between 1937 – 1947, and for years after that, it was the most commonly seen airplane at airports all over the country. Forgiving flight characteristics, light wing loading, and hands-off stability made it perfect for America’s weekend pilots. The Cub design is ideal for R/C flying and makes an excellent first-time 1/4-scale building project.
