Art Chester followed on his successful air racer the "Jeep"" with the Goon. "Goon", like "Jeep" was named after characters in Popeye cartoons and comic strips.
The Goon was built with a conventional welded steel tube frame and fabric covering. The wings used sprucespars and plywood covering. The mid-wing taildragger aircraft featured short-legged retractable landing gear. The engine was prepared to turn clockwise (as normal for some British inlines of the era) in anticipation of mounting a custom French propeller, but the propeller was also customized for American engines, and the engine needed to be modified again to rotate normally.
During the 1956 rebuild, a 190 hp Lycoming O-435-1 engine was installed in place of the Menasco, including a cut down Beech-Roby propeller and wheel brakes.
