The RotorWay Scorpion is a family of helicopters manufactured by RotorWay International.

Design and development

Derived from an original design by B.J. Schramm, the Schramm Javelin evolved into the Schramm Scorpion, both of which were developed by the Schramm Aircraft Company. A new company, RotorWay Aircraft Inc., was formed to market and produce plans and kits for the Scorpion, described as a production version of the earlier Javelin. Production of kits started in 1967 with the original Scorpion model, and ended with the discontinuation of the Scorpion 145 in 1984.

Scorpion

The Scorpion prototype was built in 1966, followed by the production of Scorpion kits in 1968.

Scorpion Too

The Scorpion Too, or Scorpion II, was the first two-seater manufactured by RotorWay. It took about 2,000 hours to complete.

Scorpion 133

Introduced in 1976, the Scorpion 133 was no different from the Scorpion Too, except for the new RW133 engine installed. This engine, the first built by RotorWay, was a 4-cylinder, 4-cycle, 133 hp engine. In 1977, because of the increased engine power, the length of the Scorpion's blades increased, from 24 ft to 25 ft.

Scorpion 145

Produced briefly in 1984, the Scorpion 145 mounted the RW145 engine developed by RotorWay.
