I've received some positive feed-back about this rotor system from pilots and engineers. One or two "uncertain critics". Let me know your thoughts about it. Completed the first power up last week-end. Been in the field so I am behind. Rotor blade chord width is a bit too short as well the span. Few more things to tweak. Hope to have it flying or crashing soon.

I have several more rotor systems, but those are only rough draft white papers.
