Yes and the 105 ISTR has an anti clockwise rotation of the MR when viewed from above whereas, if i read it correctly, the DHruv has a clockwise rotation.

So the Dhruv has the problem in a left turn and the 105 has the problem in a right turn.

Both the Lynx and the Sea King (to a much lesser degree) has the same problem in a right turn (anti-clockwise rotation) where an acceleration cross-couple caused more right turn when you loaded the rotor.

Not sure saturation is the right term since you simply run out of cyclic control to oppose the turn.
