The Barnett Gyroplane is a single-place craft constructed of tubular steel, fiberglass, and aluminum. Its pusher prop is powered by a 65-hp Continental engine. The pilot sits inside an enclosed cabin shell. The J3-M differs from the J-4B by replacing the molded fiberglass cockpit nacelle with a flat-sided fabric-covered structure. Both models are fitted with tricycle gear and disc brakes. The company has changed its name to Barnett Rotorcraft and currently markets the J-4B.
