Development
The Helicospeeder was designed by Antoine Gazda of Wakefield, Rhode Island in 1946. It was specified to carry one person and publicity releases claimed an ultimate goal of a 300 mph (483 km/h) maximum airspeed. One example of the initial version was completed.[1]
The Model 100 Helicospeeder was developed in 1947, again with a single seat. It was of all-aluminium construction and was powered by a Continental A-75 engine. One example was completed.[2]
Operational history
The designer/constructor carried out test flights and a more modest actual speed of 100 mph (161 km/h) was reached. Production examples were expected to sell for 5000 US Dollars, but no firm sales were made.[3]
Variants
Antoine Gazda planned to build the Model 101, which was intended to accommodate two persons, but no record of its completion has been found.[4]
Aircraft on display
The Model 100 Helicospeeder is preserved at the Owls Head Transportation Museum, adjacent to the Knox County Regional Airport, two miles south of Rockland, Maine.[5]
