Rotorway. Inc. was formed in 1968 to market the Scorpion, a single-seat home built helicopter. In the early-1970s Rotorway offered an unguarded version , the Scorpion Too, which featured side-by-side seating for two. The company offered the vehicle in kit form, including parts, power plant, drawings, and technical documentation. The Scorpion Too was later redesigned Scorpion 133 and offered in both turbocharged and standard versions.
