It featured a mixed construction of a welded steel tube fuselage and wood wings, with most surfaces fabric-covered, and offered side-by-side seating accessible by doors on either side.
Engine options evolved over its production, initially including Lambert, Franklin, and Warner Scarab engines, before standardizing on 115-hp or 125-hp Lycoming horizontally opposed engines in later models.
Key performance figures include a top speed of 156 mph, a cruising speed of 135 mph, and a range of 600 miles.

Introduced by the Monocoupe Corporation in 1930, the Model 90A two-seat cabin monoplane was progressively improved until production was suspended in 1942. These early Monocoupes were powered by various engines, including the 90-hp Lambert, the 90-hp Franklin, and the Warner 125-hp Scarab or 145-hp Super Scarab. The main tanks were mounted in the wing roots, providing gravity feed to the engine. Seating was for two in side-by-side fashion with access by means of doors on either side. The fuselage was of welded steel tube construction, while the wings were of wood. All surfaces, save the aluminum leading wing edges, were fabric covered. After a five year lapse in production, the Monocoupe was again built utilizing the same basic airframe but changing to either the 125- or 115-hp, Lycoming horizontally opposed air-cooled engine.
