Prototype built in Hiller's garage in Berkeley; never having flown, he crashed on his first test flight in July 1944. Undaunted, he persisted and created a most succesful post-war aviation industry. Basic design evolved into X2-235 and, ultimately, 360.

Planned use for combat troops as a "flying motorcycle." POP: 3 (the first prototype was not serialized) [56-6944/6945]. Project cancelled because of sluggish performance, a result of the Army's insistence on adding a third "back-up" engine, which also added needless weight. Interim USN designation of YHO-1E also assigned.
