Since we're pedantically discussing the rotor head of the 105/117, the only possible relative movement between the blades and the rotor head is during changes of pitch. Flap and lead-lag movement is accomplished by the elasticity of the blades. Technically you have a rigid titanium rotor head and a hingeless or semi-rigid rotor system.
One all?
Back to the issue at hand, slope landings with a rigid or semi rigid system. Again, I don't know anything about the S-92 but would be interested in any input from a current S92 driver; at least it would clear up the speculation
