CEOFOSKEY,
Thanks for the additional information.
On a related subject;
A rotorhub provides no lift and much drag. For a number of years now an idea has been bouncing around my few remaining neurons. It consists of giving the "doughnut fairings" a larger diameter and thereby a shallower elliptical X-section.
If this "doughnut" was allowed to teeter as it rotated and it was held up at the front-end of the mast, it might act as a lifting body.
