RE: Difference between CA Hinge to Pinned Hinge?
Properly installed I would say a pinned hinge has less resistance, but negligibly so. Remember when a control surface is in flight the pressure of the air flow against the surface is what the serfo is fighting, not so much the hinge. And most deflections are fractions of an inch.
Anyway, a bad pinned install - tipped, canted, glue in the seam, binding, etc. is MUCH worse than a CA hinge.
