Dave, thanks even more.

Please have a bit of patience with me on this, while sorting through it I am having to dispel some previous convictions that I've had. Generally that means I have to understand it all first.

Back to the tale of two rotors;

On your rigid rotor you mentioned that with full pitch in the blades on the left side of the aircraft it would roll (pry) right.

I'm wondering.. (uh-oh)

If the blade on the left reached the point of maximum pitch at the exact 90 degree mark wouldn't that force developed take some amount of time to transmit to the fuselage?

While the transmission of force was happening the blades would be changing their relationship to the fuselage.

Actually I think the force devlopedwould be changing it's relationship to the fuselage.

Once again, you guys are putting this into understandable verbage, thanks from everyone.
