1. A rotorcraft comprising:
a fuselage;
a tailboom extending from the fuselage, the tailboom having an aft portion;
a power system including a generator, one or more batteries and one or more dedicated yaw control system batteries; and
an electrically distributed yaw control system comprising:
a shroud coupled to the aft portion of the tailboom and forming a plurality of ducts;
a plurality of tail rotors disposed in the ducts, the tail rotors each including a motor; and
a fight control computer including a processor, the processor implementing a power management monitoring module monitoring one or more flight parameters of the rotorcraft using one or more sensors, the processor further implementing a power management command module allocating power between the power system and the tail rotor motors based on the one or more flight parameters of the rotorcraft;
wherein, the processor further implements a maneuver detection module to detect a maneuver being performed by the rotorcraft, the processor implementing the power management command module to allocate power from the generator and the one or more dedicated yaw control system batteries to the tail rotor motors in response to the processor detecting a sideward flight maneuver.
