Joepilot said, "If the spokes are hinged in flap AND lead lag at zero distance then it is not possible to rotate them at all. If they were already spinning then a change in axis of rotation would have no effect."
If the flap hinge is offset, then there will be an effect. The weights will flap at a frequency higher than that of the wheel.
Also with an offset hinge, since all the weights aren't flapping about the same point, then when you tilt the axis you add a translation at the flapping hinge to at least some of the weights. This really confuses the dynamics.
