Rigid_rotor and RW-1,. .We use a right hand grip with longitudinal, lateral and yaw, with a collective pitch trimmer (not a full blown collective control, more like a beeper for altitude changes through the altitude hold). We did away with a full collective controller on the right hand for the valid reasons that rigid_rotor notes (Laplace transforms, huh? I find them binding, myself!)
The collective pitch in Comanche is in the left hand, is similar to a short-throw conventional collective, and has a trim feedback so that in altitude hold, it rises and falls to match the power/blade angle of the rotorhead. It is purely electronic, of course. Both the pilot and copilot collectives are mechanically linked, so there is no confusion as to how much collective pitch is applied.
RW-1, your intuitive guess is pretty close!
