The H-60 series of helicopters has a tail rotor that is canted to provide both lift and lateral force. It does cause a change in pitching moment (and rolling moment) when the tail rotor thrust is changed. At the design weight/ cg condition, the mechanical mixing takes care of that - at other weight/cg conditions, the effects can be interesting. The automatic flight control system does mask some of the effect.
It was done to improve the cg range of the basic UH-60, which is quite far aft in most conditions.
