All,

I am coming up on mounting the Garmin GMU 11 magnetometer. The instructions say to mount within 3 degrees of level flight. Any idea how to determine that? Wings are off right now. I know this is some combination of dihedral and AOA of the plane itself in level flight. I am trying to translate that into an angle relative to the ribs on the underside of the wing, if that makes sense. I was planning to bolt it to a small balsa plate hysoled to the ribs, or between a rib and false rib. I guess I could try to make in adjustable, or put a shim in later through an inspection hole if I needed to, but would like to get it close out of the box.

Thanks

Scott
