I don't know where you can get the raw strips but I did install two from Aero Enhancements (http://www.aeroenhance.com/) under the eyebrow for my instrument panel on my CJ6A. It was wonderful for flood-lighting the panel and the color closely matched the florescent paint on the stock instruments. (the CJ6A normally uses a pair of UV spotlights to cause the instruments to glow yellow-green.) -- Brian Lloyd 6501 Red Hook Plaza brianl@lloyd.com Suite 201 http://www.lloyd.com St. Thomas, VI 00802 +1.340.998.9447 (voice) +1.360.838.9669 (fax) There is a time to laud one's country and a time to protest.

I have found that the DB25 style gold plated pins fit the connector, which is fragile. The same company carries DC to AC inverters, but I did not find it today with a brief search. I decided against EL lighting, because of the need for an inverter, and thus less reliability compared to LED sources. LED sources are getting very efficient, and for my map light aimed at the lap, I will be using Luxeon Stars, which run $12 to $14, and can be had in white, red, and other colors, with and without an epoxy lens. With the lens, the unit is 1" square, and draws one watt. This works out to 350 ma at about 3 volts, so you need a 30 ohm resistor if you want to run only one from the 14 volt battery. This also works well with a dimmer.

I meant this; A PIDG terminal consists of a crushable tube with a seam running along it axially, plus the tab. When I use an el-cheapo crimping tool I get all sorts of odd crimped shapes. Sometimes one side if the seam rides up over the other. Sometimes the seam actually separates, creating two minitubes, each with a few strands of wire in them. And they're the better results! Is it 'cos I'm using an e-cheapo tool? I'm sure there some published standard as to what a finished crimp should look like.

As always, the boat stuff is pricey - sometimes more than aircraft equipment (solid brass, stainless steel ... ) Did you buy the light with the LED already installed? Or did you modify a fixture? Is it a gooseneck? and How long? Sources? Many thanks for the EL info. I'll check it out.

Is it 'cos I'm > using an e-cheapo tool? Yes. Buy a decent crimper from Bob. His price is right and the tool works well. Not only have I rewired a couple of airplanes but I am in the middle of rewiring a rather large boat. A good crimp tool is worth its weight in gold. -- Brian Lloyd 6501 Red Hook Plaza brianl@lloyd.com Suite 201 http://www.lloyd.com St. Thomas, VI 00802 +1.340.998.9447 (voice) +1.360.838.9669 (fax) There is a time to laud one's country and a time to protest.

Ira N224XS ________________________________ Message 8 _____________________________________ Time: 04:39:40 PM PST US From: "Troy Scott" Subject: AeroElectric-List: trim motor braking --> AeroElectric-List message posted by: "Troy Scott" Gentlemen, I've modified an electric elevator trim scheme (originally designed by Jim Dutton) and installed it in my Glasair. I'm utilizing a DC reversible linear actuator to operate a bellcrank, much like the stock Stoddard-Hamilton design. It seems to work very well, meaning that it imparts the same range of forces to the trim springs that the original manual trim mechanism did. The airplane hasn't yet flown, but I see no reason why it won't be fine. I notice one area that could be improved: The motor doesn't stop instantly when the current is cut off. It "coasts" briefly. I know there is an electrical way to make the motor stop quickly when the current goes off, but I don't yet have any experience in this area. I've read about "magnetic braking" and "DC motor braking", but I'm not sure how to implement this feature. Suggestions?

Tasker" Subject: Re: AeroElectric-List: trim motor braking --> AeroElectric-List message posted by: "Richard E. Tasker" You just have to set it up so the motor is shorted when it is off. I don't know how you are controlling it or I could be more specific. Here are several trim circuits that Bob posted recently: http://www.aeroelectric.com/Reference_Docs/PitchTrim.pdf Note that in all cases when everything is off, the trim motor is shorted.

Here is one of the simplest and cheapest -- very durable. 1) Print labels on plain printer paper in small type (or to suit wire diameter) with either Microsoft Word or Excel. You can copy and paste to generate many dozens of labels on one sheet of paper. 2) Cut the labels off the sheet one at a time with a scissors as you need them. Two line labels work best for me. 3) Crimp roll the cut off label a bit along their length around a round toothpick or piece of wire. 4) Cut off a piece of clear shrink tube about a 1/4 -- 3/8 inch longer on each end than the length of the label. Choose a size of shrink tube that will squeeze down tight on the wire when heated. 5) Stuff the cut off and curled label into the shrink tube -- a straightened out large size paper clip (or other poking tool) can be used to center the label lengthwise in the piece of shrink tube. (Actually I normally cut off the piece of shrink tube before I cut the label off so that once I cut the label off the large paper sheet I can curl the label and stuff it in the tube without ever setting the teeny label down). 6) Slide the shrink tube with the label curled inside into position on the wire -- preferably before you crimp on the terminal unless you just want practice in cutting off and replacing terminals. 7) Heat the shrink tube with a heat gun. Admire. Move on to the next label needed. Pretty soon you realize that you can set up several labels and shrink them all with one heating of the heat gun. A tip: If you are using multiple wire connectors like AMP Mate-n-Lock or similar consider positioning the labels at different places along the various wires so that you don't wind up with all the shrink tubes clumped together.
