I fabricated a magnetometer shelf immediately aft of the baggage compartment. It is within two feet of the air handler where a small servo rests. Hopefully that servo will be infrequently cycled and thus minimal interferance with the magnetometer. I tied the surplus magnetometer wire along the side of the fuselage in the event I need to extend the magnetometer further aft. In addition, I nylon tied the bundle of wires that come from aft to the instrument panel on the right side of the fuselage.
