REFLECTOR: Grand Rapids EFIS

[Terry Miles]

Hi Y'all,

I am in the final plans point on installing a Grand Rapids EFIS.  It
will be a single AHRS mounted on canard, dual screen in front of the
pilot...side by side.  I plan to mount the EIS on the radio stack to
(hopefully) minimize the times I have to split the PFD or Map displays
to deal w/ engine or fuel issues.  

Here's my question:  Where to mount the magnetometer.  Ya know, it has
the ususal mounting guidelines:  away from ferrous, moving parts,
magnetic energy fields.  I have narrowed it to outboard on the strake,
(wings have to come off to get it back out again)or in the cabin on the
sidewall storage area which is way more accessible but subject to being
attacked by a carelessly stowed lap top or what have you.  It must be
orientated in the direction of flight.  5.25 long,  2.75 wide,  1.125
high.  Maybe the upper aft cabin ceiling?  

Anybody w/ experience on this?  Can I bury this baby in the wing and not
have to worry about it?

Terry
