This was a re-engined development of the Model 116, designed by Theodore P. Hall. A 25,5 hp Crosly engine was in the rear, powering the plastic-bodied 4-seat car and a 190hp Lycoming O-435C built on the 34,5 ft wing for flying. Pilot Reuben Snodgrass flew it for the first time on 1 November 1947 but the prototype crashed within 3 weeks due to fuel starvation. Using the same wing and another car body it flew again on 29 January 1948 piloted by W.G. Griswold. Both machines used the same registration.
