The translation of this open-cockpit sport plane’s name is “The Thunderclap” It was the airframe of this plane which 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.
