J3 Super Cub Foam Board Kit – 1010mm Wingspan

The J3 Super Cub Foam Board Kit is a semi-scale radio-controlled model designed for stable and forgiving flight. With a wingspan of 1010mm and an all-up weight of 560g, it delivers smooth handling, short takeoff and landing (STOL) capability, and excellent ground control.

The kit is built from precision laser-cut foam and ply parts and uses a combination of carbon pushrods and Z-bends for straightforward setup. Its high-wing configuration with dihedral provides natural stability, making it ideal for beginners learning to fly while still offering enough control authority for more advanced maneuvers such as slips and crosswind landings.
