1. An electric distributed propulsion system, the system comprising:
one or more generators connected to a gearbox;
a first and a second plurality of motors connected to the one or more generators, wherein each motor of the first and second plurality of motors is connected to a blade to provide thrust;
a first and a second power bus electrically connected between the one or more generators and the first and the second plurality of motors, wherein each power bus is independent of the other power bus;
a first and a second controller independently connected to each of the first and second plurality of motors, wherein each of the first and second controllers serves as a primary and a backup controller to provide redundant control to both the first and the second plurality of motors; and
dual channels in communication between pilot input sensors and the first and the second controllers, wherein:
each channel of the dual channels is independent of the other channels and comprises a primary channel and a backup channel in communication with one of the first and second controllers;
each channel of the dual channels comprises an additional channel to provide redundant communication to one of the first and second controllers; and
the additional channel of each channel of the dual channels is coupled to a primary channel of a first one of the first and second controllers and enables communication between a pilot input sensor and a backup controller of a second one of the first controller and the second controller.
