REFLECTOR: Grand Rapids EFIS

[michalk]

I have the electronic compass for my Micro Encoder.  The biggest thing 
is to keep it away from large electric currents, and soft magnetic 
sources, as these tend to have varying magnetic fields.  Constant 
magnetic fields can be calibrated out ... at least there is a procedure 
for it in my compass.

I mounted mine in the keel, just forward of the speed brake.
