I like your trim system Douwe. Where did you get the servo motor and do you
=0Athink you can post a pic? Cheers, Gardiner=0A=0A=0A=0A=0A______________

=99m gonna go with the one Mike uses, =98cause if Mikey likes it!!
!! It=99s gotta be =0Agood!!!!=0A =0ASeriously though, looks like an

g today. Have read for years about various means to get some =0Aelevator t

stem I installed a little trim servo motor in one elevator. It=99s a
bout the =0Asize of half a pack of cigarettes and only needs two tiny wires
running up to a =0Aswitch under my dash. Weighs a couple of ounces and pr
etty much fits inside the =0Aelevator, maybe protrudes 1/8=9D on the

=99ll actuate a trim tab on the elevator and =9CBobs your =0Auncle

to remove it all and smooth out. Started =0Ato finish the fiberglass work

Mark,
Thanks very much for your reply. Despite "not wanting to pound keys,"
you gave me a lot of rich info in text form, all good stuff.
My first reaction is to state that your dipole is more or less what I
had in mind for a wing installation, but as Jack P. apparently does,
I'd likely experience that polarity problem. I think the same would
be true in placing the dipole in the fuze behind the pilot, running it
fore and aft. You would know more about that.
If we can agree on that, then it is all a choice of placement of
VERTICAL antennas. I like the idea of making something, so it may
well be something like Mike Cuy's inverted quarter lambda with ground
plane. While I am a long way from needing a radio, now is the time to
install anything inside the fuze. And Ii need to consider the
location for that pesky ELT stuff. There could be more stuff than I
like behind the pilot seat.
I have saved all this antenna discussion, pix and vendors, and will
chew on it all for awhile. I'll also send to my RF buddy. You and he
could have discussions of great mutual joy, all far over my head. I
love your big array antenna, and he will, too.
Before I do anything I will call you.
Thanks,
Tim in central TX

Yeah, feel free to call Tim. I think I gave you my card, but if not my info is
in the Piet Builder's list that Jack Textor maintains and distributes. If you
don't have it, let me know.
On the dipole... while not my first choice in an antenna, I can't say that it wouldn't
work well in one airplane or another. While most of our builds are similar
(cables, fittings, etc.), there are variables that could (and probably do)
have and effect on these things. That is why I can't give a definitive answer
on what would absolutely work best for everyone... my position is simply a
reasonable starting place for someone who wishes to construct their own antenna
based on...
1. The desired pattern (omnidirectional, as in a vertical).
2. Ease of construction.
3. Simple to tune.
4. Perhaps most importantly... good engineering practices.
It's just another thing to learn along the way. I find radio fascinating... even
in these days of computers and the Internet... no, ESPECIALLY in these days
of computers and the Internet. Some might choose to dig in and learn something
else, like constructing and drilling wheel hubs... not me. I'll leave that
to someone that already has it figured out... thank you Ken Perkins! Yes, I'm
still excited about the fact that wheels are in the very near future. LOL!
