Hi,

In 1988, the preliminary design of "Heli-Stat II" was created with a balloon of a rigid structure to which four rotors (24 m in diameter) are attached, turned horizontally at take-off and vertically in flight. The project was not implemented.

 
Promotional sales film from a Canadian sponsor "Mercantile Ventures" based out of Edmonton. Just posted today!

Highlights the Helistat's utility for Forestry and Mining activities in Alberta. Payload was planned to be 60-tons.

 
From Army Aviation 1958/12.
