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.

[1] Production of kits started in 1967 with the original Scorpion model, and ended with the discontinuation of the Scorpion 145 in 1984.

In 1977, because of the increased engine power, the length of the Scorpion's blades increased, from 24 feet (7.3 m) to 25 feet (7.6 m).

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