1. An improved electrically powered rotorcraft, of the type having a rotor including a rotor hub and a pair of rotor blades mounted to the rotor hub on opposite sides thereof, the rotor being rotatably mounted on a primary drive shaft and configured to perform a 360 degree sweep, and a rotary electric motor coupled to the primary drive shaft, wherein the improvement comprises:
a common pitch-angle shaft extending between each of the blades such that angular adjustment of the common pitch-angle shaft causes a corresponding angular adjustment of each of the blades;
a limited-angle electric motor, mechanically coupled to the common pitch-angle shaft, and configured to cause angular adjustment of the common pitch angle shaft and therefore adjustment of pitch of the rotor blades; and
a controller system in communication with the limited-angle electric motor, configured to provide cyclic pitch control of the pair of rotor blades via the common pitch-angle shaft.
