You know, the kind you plug in between the headset and jacks and gives you ptt capability without hardwiring a switch into the stick. My pax stick is removable so I didn't bother with wiring some sort of plug or even a dash mounted ptt switch. My problem with my el cheapo portable ptt is that when it's plugged in it kills the intercom. The passenger can transmit and receive ok but we can't communicate with each other. I've used these switches with no such problems in other planes without a hard-wired passenger ptt (notably a G33 bonanza). The audio panel is a Garmin 340 that works great in every other respect. Is this a problem with the cheap switch or is it something in the way my stuff is wired? I don't need this capability very often but it's nice to have when I need it. Anyone else have this problem or have an idea what's going on?

When I needed a buss bar between the main and starter relays, and to join a row of circuit breaker or switches, I used a length of thick wall, soft drawn, gas tubing made of copper. I squeezed it flat and drilled the necessary holes. The flat section is between 1/2" to 3/4" wide.

What's "common" for anyone else may have no bearing on what you need/want to to do. Any of the architectures depicted will perform with greater reliability than anything certified simply because you're not saddled with less-than-the-best-by-decree hardware. >I have read comments from Bob in the archive like "don't let an unused >vacuum pad" go to waste (i.e. put an alternator on it).

If I were building an airplane today, Z-13 with dual p-mags would be my choice . . . the vast majority of OBAM aircraft being constructed today have a close or close copy of a C-172 which is what Van's sells and/or recommends in his kits. I've had at least two builders put Z-14 in their RV-8's . . . and if they're reading this and wish to join the conversation, I'm sure they can give you persuasive monologs as to their reasoning for those choices. I'm not trying to belittle anyone's offer to give you advice or an opinion but at the end of the day, the electrical system can be as personalized as your upholstery or paint job. If you bought and read the book (in particular chapter 17) what are YOUR impressions a system that meets your needs? If you have doubts, can you articulate them? It's better that we offer guidance to re-enforce or refine what's attractive to you than to give you a data dump on what everyone else is doing. Suppose you start with Z-13. Do you perceive any shortcomings? Do you have any special-needs equipment? Do you have a FADEC or EFIS system that wanders off into the woods if powered from the engine cranking battery?

Nuckolls, III" I've finished testing the Schumacher WM-1562A charger/maintainer and find it to be a very satisfactory product and good value at $18 from Wallmart. The Harbor Freight 38895 charger doesn't kick into the CHARGE mode unless the battery being serviced is below 4 volts. I DO NOT recommend this product.

Buy stock in LEDs! Eric has got some good stuff on LEDs as well as some products at www.PerihelionDesign.com and everyone should keep an eye on rapid developments in this field for aviation. I just bought a strip of EmeraLights from Wicks for $10 that illuminates the entire instrument panel with only 70mA of current. I bought a Lumiled Luxeon 1W LED and nearly blinded myself when I turned it on. Awesome power. Check out http://members.misty.com/don/led.html for a list of links.
