1. An unmanned aerial vehicle (UAV) comprising:

  • a frame having a plurality of mounting extensions, wherein each of the plurality of mounting extensions has a proximal end and a distal end, wherein each of the proximal ends of the mounting extensions is fixedly joined to the frame, and wherein each of the distal ends of the mounting extensions comprises a connection plate;

    a control system provided in association with the frame, wherein the control system comprises at least one computer processor and at least one data store; and

    a plurality of propulsion modules, wherein each of the propulsion modules further comprises;

    a housing, wherein an external surface of the housing forms a releasable connection with the connection plate at the distal end of one of the plurality of mounting extensions, wherein each of the releasable connections is aerodynamically consistent between the external surfaces of the housings and the connection plates;

    a direct current (DC) brushless motor disposed within the housing, wherein the DC brushless motor comprises a shaft extending through the housing to an exterior of the housing;

    a propeller rotatably mounted to a distal end of the shaft; and

    a motor controller disposed within the housing, wherein the motor controller is in communication with the control system.
