RotorWay Scorpion


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.
