In 1928, a group of engineers from Ryan Mechanics Monoplane Co. established Federal Aircraft Corp. in San Bernardino, California. The company’s first project was the Federal CM-1, a light multi-purpose aircraft representing a refinement of the Ryan M-1 model. William J. Waterhouse served as the chief designer for the project.
Design and Features of the CM-1
The Federal CM-1 was a four-seater, cantilever high-wing monoplane. It was powered by a 220 hp Wright J-4B Whirlwind radial engine, driving a two-bladed propeller.
Evolution and Production
After conducting tests, the prototype underwent modifications, including a lengthened nose section, after which the aircraft was renamed “Lone Eagle.” A total of two examples of the aircraft were built, registered as NX4041 and NC1724.
