The half-scale Corsair is built around a plywood box core and covered with styrofoam and fiberglass, in the manner of the KR-1 and KR-2 homebuilts. The fuselage is a standard four-longeron torsion box, while the tail and wings use conventional wooden structure. The wing is made from a laminated plywood-covered hollow front spar. The rear spar is laminated as a solid single-piece unit faced with plywood. Plywood ribs are used at the root, the center-section joints, and the tip sections. For landing gear, an air-oil oleo system is used, with either an electrical or manual ratchet system for retraction. Engines in the 65- to 125-hp range can be used, so performance varies greatly.
