Rotorway series

Mr B.J. Schramm formed a company to market, in both ready to fly and prefabricated component form, a single seat helicopter of his own design named the Javelin. This helicopter was powered by a marine outboard motor modified for use in this helicopter.

The production version of this helicopter was renamed as the Scorpion and RotorWay Inc was set up to market Scorpion plans and kits of components to amateur constructors.

The Scorpion was superseded by a two seat version - Scorpion too. This machine had a unique RotorWay designed and manufactured four cylinder water cooled engine. Scorpion Too had an empty weight of 340 kg and Max Take off weight of 544kg with a claimed cruising speed of 75 knots. Click here for a photo of the Scorpion Too.

Scorpion 133 was an improved Too with a 133 cubic inch capacity engine producing 133 HP at 4,500 RPM. Click for images from a 1980 Company Brochure - S133a  S133b  S133c   S133d   S133e  S133f 

A substantial redesign effort produced the aerodynamically improved RotorWay Exec 60.

This was followed by the Exec 90, Elite, and Exec 162F  (more) with a diversion to a four seat prototype, WindStar, in the late eighties.

WindStar was intended to be a four seat Exec derivative with a unique rigid multi blade main rotor system. It was powered by a evolutionary Schramm designed six cylinder, horizontally opposed, water cooled, overhead cam 350 Hp engine. One safety item was a one shot gas producing cartridge to put energy back into the rotor system if the engine failed.
