Don-
Your comment about mounting the magnetometer (and possibly the AHRS) at the
lateral center between the rear seat mount attach point is dead on target.
I have been flying with a Xbow unit which has Magnetometer & Attitude buil
t into one golden cube mounted at this location and have-proven that it i
s accurate with minimum hard iron interference.

This is actually a very good location for both functions since a mounting p
late from left side to right side-laying on top of the longeron is automa
tically aligned with the pitch-and roll axis. Mount the unit parallel wit
h a line from nose to tail and its also aligned with the yaw axis. No inter
nal offsets will be needed.

Here's a couple of shots showing what I did.... don't know yet if it works,
but should know next week.

I used Van's RV10 AHRS Bracket kit to install the dual AHRS from GRT.
When I bought it, I hadn't even selected GRT yet but figured the kit
would be useful nonetheless. The kit appears to work well and is
pre-drilled for the GRT and the Garmin AHRS. Could be useful for other
AHRS as long as they are not combined with the magnetometer. Photos here:

The only un-verified feature is it's alignment with the aircraft axes.
Does anyone have any experience with this setup? Comments?
Now, on to mounting the magnetometers. I've browsed the archives and
seen some of the trays built. It looks like the ideal fuselage location
is right where the rear seat belts attach. Sort of midway between the
elevator trim and elevator autopilot servo which would appear to be the
main potential antagonists. I'd welcome any additional comments from
flying builders regarding magnetometer performance. And any pics of
trays would be appreciated too.
