The semi-monocoque design is made from flush riveted aluminum sheet. The rudder is covered with doped aircraft fabric. Its 14.12 m (46.3 ft) span, semi-tapered wing employs a Wortmann FX-60-17A11-182 airfoil at the wing root, transitioning to an FX-60-126 at the wing tip. The wing has an area of 11 m2 (120 sq ft) and mounts top surface Schempp-Hirth-style air brakes.
