The Curtiss Robin, introduced in 1928, was a high-wing monoplane with a 90 hp (67 kW) V8 OX-5 8-cylinder engine built by the Curtiss-Robertson Airplane Manufacturing Company. It was later fitted with the more powerful Challenger engine, which developed between 170 and 185 hp (127 and 138 kW). NOTE: Model B (90 hp/67 kW Curtiss OX-5 engine), Model C-1 (185 hp/138 kW Curtiss Challenger engine), and Model J-1 (165 hp/123 kW Wright J-6 Whirlwind 5 engine) The J-1 version was flown by Douglas Corrigan (nicknamed "Wrongway") as well as The Flying Keys.[citation needed]
