Barnett J4B


The Barnett Gyroplane is a single-place craft constructed of tubular 4130 steel, fiberglass and aluminum. Its pusher prop is powered by a 65-hp Continental engine (originally a VW 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.
