A multi-rotor unmanned aerial vehicle (UAV), comprising:

• a housing forming a central 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 inside the cavity of the central body and adapted to control operation of the UAV;
• and
• a magnetometer secured onto an extension member at a position sufficiently distal from the housing to effect a reduction of interference from said one or more electrical components disposed within the cavity of the central body, said one or more electrical components selected from the group including a power source, flight control module, inertial measurement unit (IMU), or GPS receiver, and wherein said extension member is a landing stand configured to bear weight of the UAV when the UAV is not airborne.
