Speed for Max Nz

AMDEC posted in part:

"This should be valid in the 80-100kt range where you can reach the maximum load factor. It decreases at highre speeds."

Possibly true for some rotor designs, but newer rotors that I am familiar with produce the best flight test results in the 135-170 kias range. Perhaps you were referring to steady state rather than maneuvering Nz capability? The speed range I cited applied to maneuvering flight, i.e., pull outs of one sort or another. In those maneuvers, there are other factors that enter the picture beyond the Cl max value.
