Source-derived summary

The Gazda Helicospeeder was an American-built single-seat single-rotor helicopter of the 1940s.

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.

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.

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.

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.

Editorial analysis

Why this record matters

“Gazda Helicospeeder” is worth following because a concise public description often conceals a longer documentary argument. Here, Gazda, Helicospeeder and type provides the most credible route into that argument.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 13, 2026. The linked authority identifier is Q5529032. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1946 and 1947.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
