The Piper J-3 Cub was the most popular commercial aircraft of the 1930's.  Barely seven yards long and instantly recognizable in its yellow-and-black paint scheme, this nostalgic favorite became the foremost trainer of the era, eventually training 80% of the United States' military pilots by the end of World War II.  A new Cub was rolling of the assembly line nearly every 20 minutes, and many of these beloved airplanes are still around today. 

Hangar 9's new .40-size Piper J-3 Cub ARF captures the classic scale lines and smooth flight performance of its grandfather, a full-scale Cub owned by Pat Hartness, whose Triple Tree Aerodrome hosts the annual Joe Nall and Don Lowe Masters RC events.  Constructed from top-quality balsa and lightweight plywood materials and showing off a vibrant Cub Yellow UltraCote scheme, this scale Cub will provide aviation buffs with hours of sport-flying fun.
