The pitch and roll rates achievable in modern, semi-rigid rotor systems are much higher than those for teetering or fully articulated rotors.
Yes, but does it match the yaw rate? And what limits it?
Hence the rate of pitch change (and therefore its resulting aerodynamic effects) are at maximums 90 degrees…
Do you mean "rate of pitch change" or "pitch"?
… are at maximums 90 degrees from the point where the initial change is made (ie from the TDC or BDC).
To make the helicopter move left or right where are the maximum and minimum lift azimuths of the disk? Left and right, or fore and aft?
