I think Lu confused the mechanical control linkages with the control servos.
Any fly by wire aircraft has a vastly simpler mechanical control linkage set, this is NOT a tilt rotor attribute.
Tilt rotors have all the rotor controls of a Chinook, and the tilt mechanism, and all the airplane controls of an airplane.
SASless, I think you are on to something. Perhaps Sikorsky should develop a large cabin Black Hawk with the power of the 609, but the payload of a helicopter! This helicopter would have more range, more payload, similar operating costs, and similar purchase price to a fully developed 609!
Gee, I wonder what that aircraft would look like?
