REFLECTOR: Remote compass location

[Andrew Ellzey]

I agree with impossible to reach and I am resolved to
locate my magnetometer as far forward in the outboard
strake and just do the compass swing with the wings
removed.

    Andy,

I have the same requirement for the Dynon
Magnetometer.  We are talkingabout the physical
alignment of the unit.  And I agree it would
beimpossible to do that with the wing installed. 
Unless you come up withsome gimbaled mount that you
could adjust remotely.  Trying to doanything through
those little wing bolt access holes would
beimpossible.

Scott,The BM manual states to align your Magnetometer
withthe X,Y,Z axis of your airplane. X with the nose
Yparallel with your wings and Z straight down. I
havefired up my system on the test bench and you
candefinitely swing your heading by moving
theMagnetometer. I haven't found the step that
statesthat you can electronically adjust your heading,
so Iplan to adjust my magnetometer as close as
possiblewhen I do my compass swing. If there is an
electronicstoreable compensation, I'm hoping mine will
be verysmall.Andy--- Scott Derrick

understand, is there an adjustment on theremote
compassitself?  How odd if so...The Dynon RC is just a
little blank aluminum box witha DB9 connector,all
adjustments in software...  Unless your referring to
the physical alignment of theremote compassto the main
unit?ScottAndrew Ellzey wrote:  Thanks everyone for
the feedback, The BM manualstatesto locate the
Magnetometer at least 12 inchesfrom anysteel larger
than a 10 X 32 screw. I think Ican stillreach my
Magnetometer through the bottom 3inch holeat 12 inches
from the outboard wing bolts. Ifnot I'lljust have to
do the compass swing before Iattach mywings.thanks

   Generally, the biggest problem is strong currentsor
movingiron(ie.the nose gear).   Of course a magnetis
badthing! While the wing attach bolts are relatively
bigiron, they are notmoving which will allow the
softwareto"swing" the compass, store anystatic
adjustmentsasyou would on a compass card and
adjustitsmagneticsensing in realtime.ScottAndrew
Ellzeywrote:  With it mounted this far forward in
thestrake, didyoudo a compass swing with the
wingsremoved in ordertoadjust the mag heading? I
wanted itclose to the 3inchhole in the bottom of the
strake soI could reachitfor small final adjustments
withouttaking thewingsoff. Has anyone else located
theirmagnetometercloserto the bottom 3 inch hole with
nomagneticinterferencefrom the outboard wing
