The Ryan S-C (Sports-Coupe) was an American three-seat cabin monoplane designed and built by Ryan; one was impressed into service with the United States Army Air Forces as the L-10.
The Ryan S-C was a low-wing cantilever monoplane with a fixed tailwheel landing gear, designed to be an up-market version of the Ryan S-T trainer. The prototype first flew in 1937, and had a nose-mounted 150 hp (112 kW) Menasco inline piston engine. Production aircraft were fitted with a 145 hp (108 kW) Warner Super Scarab radial engine. With the company’s involvement in producing trainer aircraft for the United States military, the S-C was not seriously marketed, and only 12 production aircraft were built. One example was impressed into service with the United States Army Air Forces, and was designated the L-10. At the start of the 21st Century, four examples were still airworthy in the United States.
S-C-W: Production aircraft powered by a 145hp (108kW) Warner Super Scarab radial engine, 12 built.
Two SC-Ws exist with a horizontally opposed 6-cylinder Continental engine. One was modified from a radial-powered SC-W, and one was built with the 6-cylinder engine after WWII using spare airframe parts from the original pre-WWII production run.
