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]

Design[edit]

The Robin, a workmanlike cabin monoplane had a wooden wing and steel tubing fuselage. The cabin accommodated three persons; two passengers were seated side-by-side behind the pilot. Early Robins were distinguished by large flat fairings over the parallel diagonal wing bracing struts; the fairings were abandoned on later versions, having been found to be ineffective in creating lift.[1] The original landing gear had bungee rubber cord shock absorbers, later replaced by an oleo-pneumatic system; a number of Robins had twin floats added.[citation needed]

The plane's payload with 50 gal (189 l) of fuel was 452 lb (205 kg); it had a cruising speed of 102 mph (164 km/h), a landing speed of 48 mph (77 km/h), a gas capacity of 50 gal/189 l (25 gal/95 l in each wing tank), its oil capacity was 5 US gal (19 l; 4 imp gal). The aircraft's price at the factory field was $7,500.

Operational history[edit]

The aircraft Curtiss Robin "St. Louis" (right) during the record flight July 13–30, 1929, St. Louis, Missouri. Its operators were Dale Jackson and Forest O'Brine. A Flight endurance record of 17 days, 12 hours, 17 minutes was set

A single modified Robin (with a 110 hp (82 kW) Warner R-420-1) was used by the United States Army Air Corps, and designated the XC-10. This aircraft was used in a test program for radio-controlled (and unmanned) flight.[2]

Cuba's national airline, Compañía Nacional Cubana de Aviación Curtiss, was founded in 1929 with Curtiss Aircraft serving as its co-founder and major investor. The airline's first aircraft was a Curtiss Robin; it flew domestic routes as a mail and passenger transport.

From September 1929 to May 1930, a Robin C-1 was used to deliver the McCook, Nebraska Daily Gazette to communities in rural Nebraska and Kansas. The airplane flew a nonstop route of 380 miles (610 km) daily, dropping bundles of newspapers from a height of 500 feet (150 m) to local carriers.[3][4]

A Curtiss Robin C was purchased by the Paraguayan government in 1932 for the Transport Squadron of its Air Arm. It was intensively used as a VIP transport plane and air ambulance during the Chaco War (1923–1935).
