1. A multi-rotor unmanned aerial vehicle (UAV), comprising: one or more electrical components disposed in a body of the UAV and adapted to facilitate operation of the UAV, said one or more electrical components selected from a group comprising a power source, flight control module, inertial measurement unit (IMU), and GPS receiver; anda 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. 2. The UAV of claim 1, wherein the magnetometer is a compass. 3. The UAV of claim 1, further comprising a plurality of rotor blades. 4. The UAV of claim 1, further comprising a carrier for supporting a payload device. 5. The UAV of claim 4, wherein the payload device is a camera. 6. The UAV of claim 4, wherein the payload device is located between a pair of landing stands. 7. The UAV of claim 1, wherein the one or more electrical components comprises the GPS receiver, and wherein magnetometer is at least 3 cm away from the GPS receiver. 8. The UAV of claim 1, wherein the body of the UAV comprises an upper housing member and a lower housing member that are removably coupled to form a cavity of the body, within which the one or more electrical components are disposed. 9. The UAV of claim 1, wherein the body is connected to one or more branch housing members. 10. The UAV of claim 9, wherein the one or more branch housing members comprise one or more branch cavities. 11. The UAV of claim 9, wherein the body is integrally formed with the one or more branch housing members. 12. The UAV of claim 1, wherein the landing stand comprises a substantially vertical portion and the magnetometer is secured to the substantially vertical portion. 13. The UAV of claim 12, wherein the landing stand to which the magnetometer is secured extends downward from the body of the UAV. 14. The UAV of claim 1, wherein the landing stand comprises a substantially horizontal portion and the magnetometer is secured to the substantially horizontal portion. 15. A method of reducing interference experienced by a magnetometer from one or more electrical components of a multi-rotor unmanned aerial vehicle (UAV), the method comprising: providing the UAV of claim 1, thereby reducing said interference. 16. A multi-rotor unmanned aerial vehicle (UAV), comprising: a housing forming a body of the UAV, said housing comprising an outer surface and an inner surface, wherein said inner surface forms a cavity;one or more electrical components disposed within the cavity of the body and adapted to facilitate operation of the UAV, said one or more electrical components selected from a group comprising a power source, flight control module, inertial measurement unit (IMU), and GPS receiver; anda magnetometer attached onto a landing stand at a distance of at least about 3 cm from the one or more electrical components, wherein the landing stand extends away from the housing and is configured to bear weight of the UAV when the UAV is not airborne. 17. The UAV of claim 16, wherein the magnetometer is at a distance of no more than 0.5 m away from the one or more electrical components. 18. The UAV of claim 16, wherein the magnetometer is a compass. 19. The UAV of claim 16, further comprising a plurality of rotor blades. 20. The UAV of claim 16, further comprising a carrier for supporting a payload device. 21. The UAV of claim 20, wherein the payload device is a camera. 22. The UAV of claim 16, wherein the one or more electrical components comprises the GPS receiver, and wherein the magnetometer is at least 3 cm away from the GPS receiver. 23. The UAV of claim 16, wherein the body of the UAV comprises an upper housing member and a lower housing member that are removably coupled to form a cavity of the body, within which the one or more electrical components are disposed. 24. The UAV of claim 16, wherein the body is connected to one or more branch housing members. 25. The UAV of claim 24, wherein the one or more branch housing members comprise one or more branch cavities. 26. The UAV of claim 24, wherein the body is integrally formed with the one or more branch housing members. 27. The UAV of claim 16, wherein the landing stand comprises a substantially vertical portion and the magnetometer is secured to the substantially vertical portion. 28. The UAV of claim 27, wherein the landing stand to which the magnetometer is secured extends downward from the body of the UAV. 29. The UAV of claim 16, wherein the landing stand comprises a substantially horizontal portion and the magnetometer is secured to the substantially horizontal portion. 30. A method of reducing interference experienced by a magnetometer from one or more electrical components of a multi-rotor unmanned aerial vehicle (UAV), the method comprising: providing the UAV of claim 16, thereby reducing said interference.
