Mart,
If you look closely at the S300 hub, the pitch horn is exactly in line with the flapping hinge. And, the lead-lag hinge is outboard of the flapping hinge. Therefore both lead-lag and flapping have zero effect on pitch angle of the blade, not counting any aeroelastics. I suspect this is why it is feasible to have the pitch horns trail rather than lead.
