Moundsville Aircraft The Lone Eagle

Part of Lindbergh’s 1927 visit to Moundsville included inspecting the Moundsville Airplaine Corporation’s first product– a single-seat bi-plane christened by Jimmy Doolittle as The Lone Eagle, in honor of Charles Lindbergh. Despite Lindbergh’s endorsement, there were not many “Lone Eagles” produced, and the factory went out of business in 1929.

Motor Gliders Inc OHS-III / Aire-Kraft OHS-111
The Motor Gliders Inc OHS-III was built in 1929. A two-place cabin high wing monoplane powered by a 55hp Velie M-5, also Warner Scarab, it is very likely this is the Cabin-Aire monoplane that the company exhibited in Chicago in 1928.
Registered NX7950, the “OHS” designation was for company treasurer O H Snyder.
Motor Gliders Inc Buzzard Light Plane / MG-1 / Snyder Buzzard
Designed by Bud Snyder, the Buzzard Light Plane, or MG-1, of 1930 was a two-place, open, high-wing monoplane. Essentially a motorized glider with a pylon-mounted parasol wing and a pusher motor. It was fabric covered except for a dural-covered plywood fuselage bottom.
Purchased by Curtiss-Wright and is assumed to be the basis for, or at least a major influence on, the 1931 Curtiss-Wright CW-1 Junior.
The design was revived in 1983 as the kit-form, Zenoah-powered Ritz Standard A by Gerry Ritz, Wartrace TN.
