A rotor system ( 12 ) for a helicopter ( 10 ) includes a rotating shaft ( 82 ). A gimbaled hub assembly ( 56 ) is coupled to the rotating shaft ( 82 ). Rotating blades ( 24 ) and non-rotating blades ( 33 ) are coupled to the gimbaled hub assembly ( 56 ). The non-rotating blades ( 33 ) provide lift for the helicopter ( 10 ) in forward flight unloading the rotating blades. The rotating and non-rotating blades ( 24, 33 ) provide equal and opposite rolling moments for lift offset operation.
