but what would it cost, could this so called revolution can the V22 Osprey?
Two american companies:

Groen Brothers

and
CarterCopter
http://www.cartercopters.com/

work on the modern version of the Rotodyne concept, both financed by DARPA.

Funny, that allegedly it were the Americans who made the UK government to kill the Rotodyne project,
scrap all the tooling and close the company...
