I've been in touch with the Orndorff's and we've settled
on a date for what must now be about the 5th or 6th annual
weekend seminar in their facilities on Propwash Airport near
Justin, TX about 30 Miles north of Ft. Worth TX.
Details at http://www.aeroelectric.com/seminars/Ft.Worth.html
George and Becki operate Geobeck, Inc., a builder assistance
center specializing in RV's . . . there are few people on the
planet who have shepherded more RV's to completion than these
folks. This program is an opportunity to jump start the
planning on your electrical system -AND- get in touch with
some real airframe experts in the world of OBAM aircraft.

I'm a little confused about how to properly wire my slick mags.
First, a real simple, basic question about attaching the P lead to the mag
stud. This stud has a nut, splined lock washer and a large fiber washer in a
stack. I assume the p lead terminal goes between the splined lock washer and
the fiber washer. Right? Also, why is this stud flat on one side?
Second, Z-11 shows the shielded wire grounded at the mag, but note 3 says to
attach it to "engine ground." Does the mag case work as engine ground, and
is there a specific screw I'm supposed to use for this ground? Or, do I run
it to the firewall ground block?
Ignorance sure ain't bliss.
thanks,

Mark, Here's the straight skinny.
You are defining two problems. But first we have to set the stage.
An airplane sits out in the weather so it's parts are very subject to
rust
and corrosion. Thats Problem one.
An airplane moves. "They" call that harmonic motion. "We" call it
vibration.
At any rate it's a pain that has to be dealt with. Thats problem two.
Solution one. Use a crimped connection. Crimps make a homogeneous
mass and give you a lifetime gaurantee of conductivity.
Solution two. Cut off a half inch of stranded wire and put the
strands into the lug barrel along with the solid wire. You will still get
the homogeneous mass but the strands will resist vibrations and give
you a much longer life of the solid wire. HTH

I'm considering changing from individual strobe supplies to one central
unit. I've read the issues with mounting and the high voltage runs with
other wiring. Those aren't the questions I have.
I'm working on the wings (RV-8) and had planned on single power supplies
with one wire for the supply (along with the nav and landing light
supply) and use the airframe for ground return. With the single supply
I'll need to use the shielded wire, which is obviously larger. Question,
what is the diameter of wire people are using? I found a 3 conductor
shielded cable at Mouser that shows an OD of .25 inch. Is that typical?
The other question, which is more of a general wiring question, but came
up with the strobe quandary. Are connectors normally used at the wing
root so the wing is more easily removable? If so, is a shielded
connector necessary for the high voltage strobe supply or will a
standard connector work (similar to the ones on the power supply)?

| Subject: | Lighting Backlit panels |
--> AeroElectric-List message posted by: "Dave O'Donnell" <daveodonnell@direcway.com>
I have been intrigued and interested in some of the lighting issues;
LEDs and recently the UMA products (electroluminescent (EL) strip
lighting, backlit overlays (really cool!))
I think SPT is using LEDS to create some very nice looking panels.
http://www.sptpanel.com/switch_panel.htm
Then at night it looks like;
http://www.sptpanel.com/citation-night.htm
I am mentally trying to figure out exactly how it could best be done by
myself (low cost). Take a painted Plexiglas panel where the paint is
laser etched away (lettering), can you get it laser cut at the same
time? Then drill sockets for the LEDs to sit in on the backside?
The best US source that I have found so far for the EL stuff is;
http://www.beingseen.com/index.html or
http://elamusainc.com/
I think the EL stuff is dimmed by slowing the applied frequency or
lowering the voltage. They are very energy efficient, generate
negligible heat, and give off a nice even light. The down side of EL is
a little more cost and they appear to put out less light over time (70%
less after 3,000 hrs) & are damaged by sunlight. This time
deterioration may be insignificant because it appears to be operating
time. A pdf for the EL wire is below;
http://elamusainc.com/PDFS/5mmCommon.pdf
All interesting mental exercises at this stage for me. I think the LED
panel could look very professional, anyone out there already know how to
or the best way to do the backlit panel as in the links above.

I'm starting to wire my radios. I'm looking for a lesson on how to install
the close-barrel pins that come with the radios using the RCT-3
crimper. How much wire should be stripped, should any insulation go inside
the barrel, etc.?
Thanks,

I am installing an all electric system on my Seawind and need to know what
alternators from B&C to order. B&C lists them as 200G 12 amp alternator and
an
SD 8 alternator. Are these stand by alternators? I thought that I was
supposed to use a 60 amp and a 20 amp alternator. Are the 200G and the SD8
the correct ones?
Please help.

L-60 and SD-20 would get you 60 and 20 amps.

Hello Jim,
use a tool like netvampire (www.shareware.com) or similar, this does save
the content and is able to restart where it broke, or easier, buy the CD
with all the stuff from Bob =(;o)
Kind regards
