In 1969 Hazel Sig, Then President of Sig Mfg. Co., rebuilt a standard 1941 Piper J-3 Cub for airshow flying. To increase the plane’s aerobatic performance, 40 inches were clipped off each wing panel and the engine was reworked for greater horsepower.
The result is a highly aerobatic Cub that is a real joy to fly! Smooth aileron rolls, snap rolls, immelmann turns, and many other rolling maneuvers which are difficult in a standard wing J-3, are easy with the Clipped Wing Cub.

This 1/6-scale model inherits all of the delightful flight characteristics of Hazel’s full-scale Clipped Wing Cub.
