Adam,
I realise that i misunderstood your post - you are asking if gyroscopic precession is still relevent for a rotor with direct control.
The answer is still yes. Instead of a cyclic the pilot directly controls the pitch of the blades, but it is still 90 degrees lead. By angling the teetering pivot angle to less than 90 degrees you can also compensate for coning and wee-wa.
A search in google should find the various threads that discuss those.
PPRuNe search never seems to work that well.
