The rotor yoke further includes a plurality of pitched yoke arms. Each pitched yoke arm is coupled to the hub portion and includes one or more feathering bearings. Each pitched yoke arm includes a precone axis that is elevated at a precone angle relative to a plane of rotation of the rotor yoke. Each pitched yoke arm includes a twist axis that is twisted at a twist angle relative to the plane of rotation of the rotor yoke. Each rotor blade is configured to couple to a pitched yoke arm via the feathering bearings. Each rotor blade includes a root end that comprises a twisted shape to match the twist axis of a particular one of the pitched yoke arms.
