    From: "Ianrat" <ianrat@powerup.com.au>
    Trying to wire up my 601. What gauge wire should I use on things like the fuel senders. I was considering using 20G. I will be using 18G for things like lights that draw a bit of power. Thank you. Ianrat Read this topic online here: http://forums.matronics.com/viewtopic.php?p 1769#201769

    Subject: Re: Hook up wire
    Heres an excel file you might find useful: http://www.rst-engr.com/rst/jimsdata/index.html Click on "Wire Table". A good rule of thumb is to size the wire for no more than a 3% (about half a volt for a 14V system) voltage drop over the length of the wire at the maximum current the circuit will see and use a fuse or circuit breaker that will allow no more than about a 20C temperature rise at its rated current. Here's another chart that might be useful: http://home.hiwaay.net/~langford/wiresize.html This data in this chart looks about right to me. 20 gauge wire will work fine for the fuel senders. 18 gauge will probably work for the nav lights if the current is not much more than 5 amps. The 3% voltage drop rule isn't too critical for simple lighting circuits. Personally I would use 16 gauge for most of the lighting circuits and power feeds and use the smaller stuff for wiring up signal lines in the panel and audio circuits. Halogen type landing lights will require at least a 12 gauge wire due to the long run and high current. Some of your gauges might require a relatively large ground wire (16 gauge or so) to minimize the voltage drop to ground for better accuracy. I ran most of my ground wires to a common terminal block adjacent to the point where the main battery ground was located. This helps to reduce the chance of noise in the audio circuits.

    From: "Lee Steensland" <lee@steensland.net>
    I went to the crash site and took a few pictures with my cell phone camera. It was an Corvair powered XL. I have spent many an hour in his hanger chatting him up about it. The last time I talked with Ken he said he had some issues with his carburetor. He went so far as to talk to WW at Arlington about it and ways to resolve it. He got his sign off last week and I guess he didn't have all the kinks out of his carb. Ken is the reason I started building, and the reason I decided to use a Corvair. With him gone, there is a big hole where my motivation used to be. Read this topic online here: http://forums.matronics.com/viewtopic.php?p 1870#201870

    Im sorry for your loss, Lee. Good friends are hard to lose and itll take a considerable while for you to look on this with an unemotional perspective. Take heart knowing that you will, eventually. Id recommend giving it some time and not selling the project just yet. The issues he had with the carburetor will be of considerable interest to Corvair builders and persons using carbs per se. Do you have any specific idea of the difficulties he was experiencing with his fuel system?

    I don't ever want to know what its like to loose a buddy in an experimental crash, especially when it's something like this. Sorry for your loss Lee. Looking at the crash damage, it looks like he stalled and went straight down. Usually, the FAA will site the cause as pilot error, for stalling the plane, with a secondary factory of engine problems, but he probably had no place to land and tried to keep it in the air, thus the stall. Carb problems don't need to equal crash, so lets all learn from this and keep our planes near the runway and away from population until we have sorted out these problems. It's always best to play it safe, especially when you know there is a problem, and work it out where you can make a safe landing if necessary.
