The language translation of this open-cockpit sport plane’s name is “The Thunderclap.” The airframe of this plane was used as the foundation for “Mr. America.” Both share similar wings, fuselage, tail unit, and landing gear. The wings are a wire-braced shoulder type with two simple beam spars. As with the Mr. America, seating is for one behind a modified Volkswagen engine turning a two-blade wooden prop.
