We mounted a vertical card compass in the panel area above the gear retract
lever, and it has worked just fine. Our maximum deviation on the compass
card is only a few degrees. We did make an effort to keep magnetic hardware
and wiring away from the compass. It is easy to see the effect of a
magnetic object (e.g., a steel screw) by moving it around the compass at the
expected distance. The disturbance varies greatly with angular position at
a constant distance from the compass.
