busdriver,
I'm assuming you're talking about lack of left roll control authority in a high G right turn (assuming a counter clockwise rotating rotor system) which is ironically the exact situation I was going to bring up to counter your gyro discussion. How would you explain this in a rotational dynamics concept?
I was thinking about what I understand is called "servo transparency".
I would say that the high angular momentum be especially resistant to redirection in the more extreme conditions with more lift, although that would only be the case if the rotor speed was higher. Just having higher pitch doesn't change the angular momentum. I would say that this would apply to any manufacturing nations' rotational sense or any change of direction.
