Curtiss V2-3

In 1916 and 1917 Curtiss produced R-3 and R-4 airplanes for the U.S. Army Signal Corps, some of which the 1st Aero Squadron used during the Mexican Punitive Expedition. The Curtiss V2-3 engine, rated at 200 hp, powered both those airplanes; however, it had a poor power to weight ratio -- almost four pounds for every 1 hp -- which hurt aircraft performance. By comparison, the World War I Liberty engine had a ratio of two pounds weight per horsepower.
