    Default Mount AHRS and Magnetometer

    I purchased the MGL system that comes with the small magnetometer and AHRS. Having read the constraints on mounting, I conclude that you can't meet them all.

    I was thinking about mounting them above the passenger compartment on a small aluminum piece that would extend across the compartment above the fuselage structure - basically mounting them in the center of the wingspan. I took my trusty Iphone up there and the compass works well for about a 6" diameter in the center of this area.

    I know many have mounted them outside on the wing, but I am not excited about mounting it that far from the longitudinal axis.

    Thanks

    Tom, Think twice about that location. When sitting in the seat... wearing your headset... magnets in the speaker cups!! When visiting a builder of a VariEze he had a vertical card compass mounted, I moved the headset he had hanging on the throttle and the compass moved 30 degrees.

    Just a thought.

    I think the wing tip is your best bet. You will still get accurate bank angles.
