Hazel Sig’s World Famous Clipped Wing Piper Cub

In 1969, Hazel Sig, co-founder of SIG Mfg. Co., rebuilt a standard 1941 Piper J-3 Cub for aerobatic flying. To increase performance, 40" was clipped off each wing panel and the engine reworked to produce 75 h.p. The entire framework was rebuilt and a dazzling sunburst paint job was applied with SIG Supercoat Dope.


Over the years, Hazel progressed to more powerful airplanes for her aerobatics, but none ever captured the affections of modelers worldwide as has the Clipped Wing Cub.

In the air, the Clipped Wing Cub is smooth, stable, and responsive as the big one. Basic aerobatic maneuvers such as loops, rolls, spins, and snaps are easy. A beautiful model of a truly special airplane! Available in two sizes - 1/4-scale (86" wingspan) and 1/6-scale (56" wingspan).
