A rotor system for an aircraft that includes one or more rotor blades respectively connected to the rotor via a blade cuff, and a method of manufacturing the rotor system is disclosed. The rotor system includes (i) a blade cuff coupled to a blade, wherein a distal end diameter of the blade cuff is larger in diameter than a middle portion diameter of the blade cuff, and (ii) a blade. The blade is wrapped in a plurality of fibers. At least a subset of the plurality of fibers extend longitudinally down the blade from wrapping the middle portion diameter of the blade cuff and continuing past the distal end diameter of the blade cuff. The blade comprises a plurality of weights disposed in a forward edge section of the blade to balance a front side of the blade and a backside of the blade.
