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, wherein the central cavity is configured to house one or more electrical components configured to control the operation of the UAV;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, andone or more electrical components disposed inside the central cavity, 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);a magnetometer attached onto a landing stand at a position sufficiently distal from the one or more electrical components to effect a reduction of interference from said one or more electrical components, wherein the landing stand extends away from the body of the UAV and is configured to bear weight of the UAV when the UAV is not airborne;wherein the one or more branch housing members are configured to support one or more actuator assemblies, each actuator assembly comprising an actuator configured to effect movement of the UAV, wherein the thrust of the one or more actuator assemblies is oriented in a vertical direction relative to the central body, andwherein at least a portion of each of the lower branch housing members extends beneath at least a portion of the corresponding actuator. 2. The UAV of claim 1, 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. 3. The UAV of claim 2, wherein the magnetometer is at a distance of more than 3 cm and no more than 0.5 m away from the one or more electrical components. 4. The UAV of claim 1, wherein the upper branch housing member and the lower branch housing member form a branch cavity within a corresponding branch housing member. 5. The UAV of claim 4, further comprising 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. 6. The UAV of claim 5, wherein the one or more ESC modules each is located within a corresponding branch housing member. 7. The UAV of claim 5, wherein the upper branch housing member and the lower branch housing member have substantially the same length. 8. The UAV of claim 5, wherein each ESC module of the one or more ESC modules is electrically connected to the flight control module and the corresponding actuator assembly, wherein the flight control module is configured to provide control signals for the ESC modules, and wherein each ESC module is configured to provide actuator signals to the corresponding actuator assembly. 9. The UAV of claim 8, wherein each ESC module of the one or more ESC modules is operably connected to the flight control module to permit two-way communication between the flight control module and each ESC module. 10. The UAV of claim 1, wherein the central cavity has one or more interior structures formed therein configured to accommodate the one or more electrical components. 11. The UAV of claim 10, wherein the interior structures comprise slots, grids, or housings that accommodate the one or more electrical components. 12. The UAV of claim 1, further comprising an energy source located with the central cavity, and configured to provide energy to the one or more actuator assemblies. 13. The UAV of claim 12, further comprising an opening configured to permit the energy source to be retrieved from the central cavity or inserted into the central cavity. 14. The UAV of claim 13, further comprising a cover hingedly coupled to the central body to selectively cover the opening. 15. The UAV of claim 1, further comprising a carrier for supporting a payload device. 16. The UAV of claim 1, wherein the magnetometer comprises a compass. 17. The UAV of claim 1, wherein each actuator assembly comprises a rotor blade and an actuator configured to actuate the rotor blade. 18. The UAV of claim 1, further comprising an indicator light source, wherein the indicator light source is positioned at an opening or window. 19. The UAV of claim 18, wherein the opening or the window is made of a transparent or semi-transparent material.
