The problem with using a connector, though, is that if you need to remove the elevator, you'll have to remove the connector...not convenient. (at least that's the way it is on an RV...just a small round hole for the wire to pass through the elevator spar) Here's what I did instead: http://www.rvproject.com/20040124.html I used D-sub pins and sockets, and that's it. No connector body to worry about. Heat shrink over each pin/socket pair, and then heat shrink over the bundle. Need to remove the servo, cut the heat shrink, pull the pins/sockets apart. Need to remove the elevator? Same deal, and there's no fat connector to worry about. Best of luck, )_( Dan RV-7 N714D http://www.rvproject.com ----- Original Message ----- From: "Kenneth Gresham" Subject: AeroElectric-List: Quick connects > --> AeroElectric-List message posted by: "Kenneth Gresham" > > Does anyone have a suggestion for a simple quick connection for five or more wires.

On my MCR SPORTSTER (ROTAX 912 and Z-16), the line from terminal 5 on S1, Master Switch and the 5A CB is 2" long. The line from the 5A CB and the MAIN BUS is 4" long. Can I use 22AWG for the two line, without FuseLink ? I have sawn on some aircraft silicone sleeves to "protect" FastOn terminals. I use B&C ones. I never read anything about that on the Aeroelectric list. Usefull or useless ? Thanks again for the job you do for us.

My whole airplane is made of epoxy, maybe I'll just drill a little hole in the fiberglass panel, stick the LED into the hole and glue it in place with 2 minute stuff. I'm thinking one LED aimed at the top back side and one at the bottom should give plenty of illumination.

We're all aware of the ever increasing shrillness of voices decrying this gawdawful pollutant and that stress on the environment with all too many politicians ready to mount up with their white hats on and come charging over the hill to our "rescue". Problem is that there's so much BS stirred in with the real science that it's difficult to sort out the pieces. Solders in hardware stores for copper plumbing have been lead-free for a lot of years. Yeah, I can see some basic logic in that . . . we DO drink water that flows past the joints. You might poke around on the 'net and see what the rumblings are about non-lead solders for electronics. Not having any good information one way or the other, I'd stick with what we know works VERY well, good ol' 60/40 or 63/37 tin-lead with a good flux. Get a name brand like Kester or Multicore. >Bob, I've ordered the circuit board for your Audio Isolation Amplifier. I'd >like to use it to eliminate the need for an audio panel.

There are a ton of features we could build into an audio system . . . but that means going toe-to-toe with folks who have been doing that for years and doing it rather well. I prefer to offer goodies you can't get anywhere else -OR- item that can blow away some piece of junk already in the markeplace. >In your book I read about the method for trimming the quarter-wave dipole >antennas like I have installed in my Glasair.

Here's the gold standard in thru-line wattmeters. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3074027135&category=48701 You also have to have a "slug" that covers the frequency and power range of interest. They're kinda pricey for a one time need. See if you can borrow/rent one from a local two-way radio shop . . . or pay one of their techs to come out and do a look-see on your antennas. Here's my favorite antenna tool. http://www.mfjenterprises.com/products.php?prodid=MFJ-259B >I've been planning to mount my transponder antenna on an aluminum inspection >cover.

The purists will debate at length and with enthusiasm as to the effectiveness of finely tuned antennas. Fact is that from an airplane, everything you talk/listen to is line-of-sight . . . a wet string would get you 90% coverage of your area of interest. When it's EASY to be precise, why not? If convenience drives you to consider the inspection plates, go ahead. Nobody will know the difference but you . . and that only because you took the time to worry about it a little.

In various wirebooks I see AWG 20 and AWG 18 as wire to pin 6 (bus voltage) on the LR-3's. For a 70 amp main and 20 amp secondary alternator which combo is best: 24AWG Fuse link and 20 AWG? or 22 AWG fuse link and 18 AWG? Many Thanks, John Schroeder. -- ________________________________ Message 8 _____________________________________ Time: 07:12:15 PM PST US From: "Robert L.

If the wire between bus and regulator is long (say over 6 feet) we'd like to minimize resistance . . . I'd go 18/22 just for grins. Otherwise 20/24 is fine.
