A preferred embodiment of a rotary-wing aircraft includes a fuselage, a tail boom fixedly coupled the fuselage, a pylon fixedly coupled to the tail boom, and a main rotor assembly rotatably coupled to the fuselage and comprising a hub and a plurality of rotor blades pivotally coupled to the hub. The preferred embodiment also includes a cyclic control adapted to vary an orientation of the rotor blades in relation to the hub on a cyclical basis, and a horizontal stabilizer mounted on one of the pylon and the tail boom. At least a portion of the horizontal stabilizer is movable in relation to the one of the pylon and the tail boom and a position of the at least a portion of the horizontal stabilizer is controllable independent of the cyclic control.
