Berliner CM-4 Sportster

The Berliner Aircraft Co. had pro-duced one commercial airplane in addition to the two earlier experimental direct lift machines. The CM-4 Sport-ster, a high-wing parasol aimed at the private pilot market, was powered by an OX-5. One large cock-pit seating two was located directly under the large wing. The front end was much like that of the Travel Air 2000, complete with the same rectan-gular radiator. Landing gear was a split axle type, horizontal surfaces a pleasing elliptical shape and the ver-tical tail an almost complete circle, though this was later changed to a lozenge shape.
