Design and developmentEdit
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.
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.
An example of a 1924 Dormoy Bathtub fuselage with a Heath-Henderson engine is on display at the Motorcycle Heritage Museum in Westerville, Ohio. A large scale model of a 1924 Dormoy Bathtub is on display at the International Sport Aviation Museum in Florida.
