ERLA-Maschinenwerk GmbH
Germany
Though established in 1934, the real beginnings were in 1933 as Nestler und Breitfeld of Erla. Type Erla 5 was a single-seat monoplane with an engine of 20 hp. From 1934 undertook quantity production of Arado Ar 65 and Ar 68, He 51 and Bf 109 (including early “C” sub-type from 1937, as well as numerous later variants). Also produced assemblies for other military types.

It was a pusher biplane of Curtiss type with variable incidence lower wings with a span of 30″, a 4-cyinder. Knox 225 auto engine, removed from Ericson’s own Buick, and a total weight of 800-900 lbs. No flight was recorded. Ericson built three more machines. All crashed, and the last crash broke his hip and forced him to retire from aviation.
ERCO (Engineering Research Corp.)
USA
Established 1930, Henry Berliner was the founder of Berliner Aircraft Company, and founder of Engineering Research Corporation, Riverdale, Maryland- producer of the Ercoupe.
After making important components for other aircraft, designed and built the novel Ercoupe monoplane, developed from the original Weick “easy-to-fly” type and first flown in October 1937. Fred E. Weick was the company’s chief engineer. The type was notable for its control system, which eliminated rudder pedals, and was first marketed in 1940. Production ceased on U.S. entry into Second World War, when company was fully engaged in defense contracts. Difficulty of obtaining duralumin led to redesigned Ercoupe of composite construction in 1941. In August 1941 one was used to demonstrate benefits of jet-assisted take-off (JATO) compared with conventionally- powered aircraft. Two examples were bought by U.S. Army as experimental radio-controlled targets. After the war civil Ercoupe production was resumed.
