The Dormoy Bathtub was a simple-to-construct, high wing racing aircraft of the 1920s. [2]
The Bathtub was developed by Etienne Dormoy, a French engineer at McCook Field in Dayton, Ohio as a simple low-cost and ultra-light aircraft. Dormoy would later design the Buhl Bull Pup. [3]
The aircraft used a steel tube fuselage, with an exposed tail section. The parasol wings used wood spars with fabric covering supported by steel lift struts. The ailerons used steel control cables that were exposed in front of the leading edge of the wing. The engine was a modified Henderson motorcycle engine purchased for $325. [3]
The Dormoy Bathtub competed in the 1924 and 1925 National Air Races, winning the Rickenbacker Trophy in 1924. The 1925 model featured a fully covered tail section, removing its "bathtub" appearance. [4]
An example of a 1924 Dormoy Bathtub fuselage with a Heath-Henderson engine is on display at the Motorcycle Heritage Museum in Westerville, Ohio. [5] A large scale model of a 1924 Dormoy Bathtub is on display at the International Sport Aviation Museum in Florida. [6]
A homebuilt design was produced by Mike Kimbrel, the Kimbrel Dormoy Bathtub Mk 1, using a 40 hp (30 kW) Volkswagen air-cooled engine. [7]

The Ace Baby Ace, a single-seat, single-engine, parasol wing, fixed-gear light airplane, was marketed as a homebuilt aircraft when its plans were first offered for sale in 1929 — one of the first homebuilt aircraft plans available in the United States. Plans are still available and Baby Aces are still being built. Orland Corben designed a series of aircraft for the Ace Aircraft Manufacturing Company, the Baby Ace, Junior Ace, and Super Ace. Corben's name was associated with the aircraft, and it is commonly known as the Corben Baby Ace.
