18. A rotor assembly comprising:
a hub assembly including a hub and a first coupling configured to couple the hub to an actuator;
a shaft assembly coupled to the hub assembly with a second coupling, the second coupling being configured to facilitate rotation of the hub relative to a shaft of the shaft assembly; and
a rotor blade coupled to the hub assembly with a third coupling, the rotor blade being configured to rotate with the shaft;
wherein the shaft includes arms extending from a proximal body of the shaft;
wherein the hub includes pairs of extensions that extend from a surface of the body, each pair of extensions receiving and coupled to a respective one of the arms;
wherein the first coupling transmits movements of the actuator to the hub to facilitate cyclic pitch control of the rotor blade.
