Autogiro Company of America AC-35

The Autogiro Company of America AC-35 was an early attempt to make a roadable aircraft in the United States during the 1930s.

The vehicle could fly at high speed in the air, and drive at up to 25 mph (40 km/h) on the ground with its rotors stowed.

The fuselage was a combination of steel tube in front, and wood construction in the tail with fabric covering overall.

[3] Ray drove it to the main entrance of the Commerce Building where it was accepted by John H. Geisse, chief of the Aeronautics Branch.

Inc. in Carmel, Indiana, licensed the AC-35 with an intent to produce a non-roadable variant, powered by a 135-hp Lycoming O-290-D2Bs engine.
