The problems happen at the terminations. I recommend connectors with properly designed stain relief. I have selected a Switchcraft EN3 series connectors (http://dkc3.digikey.com/PDF/T063/0289.pdf) This is a small diameter circular connector that is weather tight and strain relieved. It's more money than a cut-up D connector but it's a reliable stable connector. I will add a length of plastic tubing where the wire is routed through the elevator hinge area supported by clamps on both ends. Ralph Robert L.

Five 22ga for MAC trim and two 20ga for tail light/whatever (and just whut the doktur ordered for TruTrak servos). Take them wimpy wires from the MAC servo, strip back twice what you need for a butt splice, double it over and crimp. I also add a short skinny piece of heat shrink to the insulation to make sure the PIDG butt splice grabs aholt of the insulation... Here's a suggestion from Bob Nuckolls at aeroelectric.com: http://www.aeroelectric.com/articles/macservo/macservo.html and others have crimped d-sub pins with shrink tube over each connection (female to harness, male to servo at staggered lengths to avoid "snake swallowed a pig" syndrome) to the wires to make the connection as well.

He has an ICS Plus nav/com that had been marketed by Wag Aero at one time. It is now malfunctioning, and he would like to try to get it serviced. So far he's had no luck, either through Wag or the Internet. Although not exquisitely intuitive to use, it does have a lot of pretty neat and useful features, and I don't blame him for trying to get it fixed. Does anyone on the list have any (constructive) suggestions? glen matejcek aerobubba@earthlink.net ________________________________ Message 5 _____________________________________ Time: 06:23:41 AM PST US From: "Jim Pleasants" Subject: AeroElectric-List: wingtip VOR antenna As a part of the installation of the landing light package in the wingtip, I put in a 6-inch strip of aluminum foil which came in the kit as a heat shield. I'm now contemplating (obsessing?) over the location for the VOR antenna. Will the strip of aluminum foil make a substancial difference in the reception capability of a wingtip antenna? All comments will be appreciated -- and Merry Christmas to all!

EVERY conductor located within inches of ANY antenna will have SOME effect. If we were blessed with access to some of the very sophisticated antenna modeling and performance predicting software, we could probably quantity the degree to which your contemplated configuration is affected. No antenna mounted on an airframe is "perfect" and many suffer from deep performance nulls on some look-axis . . . yet most antennas are deemed "satisfactory" by users who fly them. Anyone's non-quantified predictions attempting to answer your question might just as well be offered by throwing darts at the whole range of possible answers. Give it a try and if you perceive some degraded performance, you're in a position to do the repeatable experiment where the foil is removed and the antenna re-evaluated in the same operating conditions.

The authority rests with experiment. --Lawrence M. Krauss Thanks for the follow up and feedback. The need to experiment at the wrong time has been averted. I appreciate it.

Excellent ideas are forming. Nathan Ulrich's annunciator is very nice. I'm getting anxious to get more info on the caution/annunciator panel. I'd like to build one when the entire concept comes together. Or buy one if somone decides to produce them.

I had a picture for the individual d-sub pins under shrink but I don't know where it got off to. I'm planning on adding it to the options in the comic book. Ain't electronics wunderful . . .
