Magnetometer??

David,
Hi, I don't know what the brand name of the magnetometer is, the system I
want to get is made by Garnd Rapids Technologies. I have the "Installation
Guide" which is vage as heck. I wanted to build a platform to mount it on in
the wing( nothing showing outside). My wing is full of junk, ferrous nuts,
bell cranks(two), electric fuel transfer pump, cables, and strobe wiring.
Today, I went and looked at another plane, it's a glastar without aux tanks.
He has a Blue Mountain system(high dollar), and his is about 6 inches away
from the bellcrank and right over a inspection plate(ferrous nuts). The
strobe wires are about 10 inches away, he says it works great.
I would think that all of these things work the same and should be just as
sensitive as the next. I'm going to put it in the right wing cause it's the
one on the table now. I won't know if it works or not until I finish
building. Oh, I haven't bought the system yet, I ordered the magnetometer so
I could mount it. If you want when I get it, I'll send you the info on the
unit.

David, which magnetometer are you using and where did you buy it, please?

Are you kidding? The last wood plane two wood planes I saw had more
nails in them than there are rivetts in a metal plane. The wing ribs
were built just like those in a model plane, except they used small
nails instead of pins. Tail, rudder, horizontal stab, elevator... All
the same way.

True, some use nails, and some use tack strips and pull all of them after
the glue is set. Some don't. I don't know what I was thinking. Reality is
a lot different than ideal practice, huh?

My wood plane would have no nails, and no metal in it at all. Ceramic
engine, Kevlar cables, Unobtanium where necessary ....the whole works. I'm
not even going to use a transponder. I'm going for stealth, you know.
Staying under the radar. g

Kinda like the tail in my G-III where they have you put the nav
antenna. Of course it's molded right to a carbon fiber shell.
Maybe it'll work, but by the time I get to use it I may be too old to
care.

Then there's all the salt from the sweat of working inside there.
Does swearing add to conductivity or magnetism? If so, how do your
degauss a fiberglass airplane?

Let's hope they at least used non magnetic stainless nails..... Oh, there
goes that darn ideal vs. reality again. g

You could always go with brass which is diamagnetic.

Man, I thought there was a lot of detail in the G-III and there is,
but after I watched Jack build the GP-4 and saw the insides of the
Barracuda I'd hate to see something with a *lot* of detail..

Low wing, high wing, electrical system, instruments installed, makeup of
instrument panel and materials used in the mountings? More details, if
anyone is to give a reasonable answer.

At least I asked for more details. That would help, in this case.

I think I don't like which way this whole thread is headed, anyway. I'm
going to back out gracefully..... or maybe stumbling! g

Yes, please do.

magnetometer

Commonly called a flux gate in the airplane business. It is nothing
more that a mag compass that has outputs to run to the DG etc to tell
where it is pointing. Treat it like the whisky compass and you won't
have any problems. Just like any other compass, it can be compensated
for minor interference, so you don't have to be paranoid about it.
Just don't run the strobe wires over it or use ferris screws to tie it
down.

Aren't ferris screws used to hold a ferris wheel together?

Hi Jim, have you thought about that 500 cycle tone, I could use some
suggestions.

Ferris: Cameron has never been in love - at least, nobody's ever been in
love with him. If things don't change for him, he's gonna marry the first
girl he lays, and she's gonna treat him like ****, because she will have
given him what he has built up in his mind as the end-all, be-all of human
existence. She won't respect him, 'cause you can't respect somebody who
kisses your ass. It just doesn't work.

That state government and its online regulation of flying gnomes is
disturbing...

To say nothing if this is to do with somethings sexual orientation
instead of the ramifications of excessive pixie dusting...
