To 212 Man,
The term high mounted refers to the fact that the line of tail rotor thrust is located above the longitudinal center line that intersects the CG. This positional relationship allows the tail rotor thrust to introduce a right roll during the recovery from a zero G event. I remember seeing a reference to it in some Robinson literature but I am unable to locate it.
