Curtiss Robin C-1
The Curtiss Robin, introduced in 1928, was a US high-wing monoplane built by the Curtiss-Robertson Airplane Manufacturing Company. It offered the advantage, over its open cockpit contemporaries, of a closed cabin in the late 1920s and early 1930s. The Curtiss Robin C-1 (Model 50C) was powered by a 185 hp Curtiss Challenger radial piston engine. Over 200 were built.
