Cool

Thanks Heedm, good point.
You said: >>The interrupted lift on the left side of the disk acts similar to inputting aft cyclic. Whatever explanation you want to give at this point will fill in the blanks I have above.<<

I agree, it does act similarly (I think) to aft cyclic but I would like to avoid reference to a different cyclic position because it introduces more variables. Perhaps I should have explained it thus:

As the stall causes the blade to reach a reduced high point over the tail, the tip path plane can effectively be now thought of as lower at the rear than the pre stall condition. As the system attempts to align the rotor mast perpendicular to the tip path plane, the lower rear blade position will manifest itself as a fuselage pitch up, i.e. the nose pitches up.

How does that sound?
