1. A multi-rotor unmanned aerial vehicle (UAV), comprising:
- a central body comprising an upper housing member and a lower housing member, the upper housing member and the lower housing member forming a central cavity;
one or more branch housing members extending from the central body, the one or more branch housing members each comprising an upper branch housing member and a lower branch housing member,wherein the one or more branch housing members are configured to support one or more actuator assemblies configured to effect movement of the UAV,wherein the one or more upper branch housing members and the upper housing member form an integral upper body portion, the one or more lower branch housing members and the lower housing member form an integral lower body portion, and the integral upper body portion and the integral lower body portion are removably coupled to form a hollow body portion comprising the central cavity;
one or more electrical components disposed inside the hollow body portion, wherein the one or more electrical components (1) are configured to control the operation of the UAV, and (2) comprise at least a flight control module and an inertial measurement unit (IMU); and
one or more electronic speed control (ESC) modules, each electrically coupled to a corresponding actuator assembly of the one or more actuator assemblies in order to control actuation of said corresponding actuator assembly,wherein each ESC module is not located within the central cavity.
