Red, green , yellow, and white. Just mark the glass on the instruments according to the chart on the ZAC web site. One of these days, I might get the stickers thay sell at AS&S or Wicks. For the labels, I used a label maker that can be bought at the same place. I got silver tape with black lettering. You can program most of them to draw a box around the label. If I decide I want something that looks better, I'll just scrape them off and have something made. The guy I share a hangar with, used some clear Avery lables and printed them on a laser printer For the fuel tanks, I used the white paint marker to write the grade and quantity near the fuel cap. My DAR didn't have any problem with it.

Say one cylinder has been misfiring or running too lean.

The two contacts of the bulb go to either side of the filament. The outside base of the bulb is not connected to the filament. Automotive/Motorcycle bulbs generally have one or two contacts on the bottom of the bulb. Each base contact is one side of a filament. The outside of the base is usually ground, for the other side of the filament(s). The bottom of the Zenith supplied bulb LOOKS like a standard dual filament bulb. A single filament 1156 bulb has a single contact on the bottom. This single contact will short the two contacts (Power and ground) in the socket supplied from Zenith. [Wonder how I know ?? :-( ] The bulb supplied from Zenith is a 1076. It is available from auto part stores. It is NOT an airplane specific part.

Also the filament of a 12 V bulb will read as a short (one ohm or less) on an ohm meter. It only has a higher resistance when it is on, that is, the resistance goes up with temperature.

There was a constant crowd around the WW 601 at the corner of the Zenith area. I was fortunate enough to meet Gus Warren and his wife, william and Grace, and the Heintz family. The 601/ Corvair, called ZenVair, is awesome...I took pics , will post if I can figure out how, but suffice it to say it is well put toghther ( an understatement) ... apparently WW did not, at the last minute , get FAA approval to fly, so he trucked it there...has performed taxi tests, and is expecting great things. He...and the Zenith people, are nothing but helpful... WW spent a lot of time with me and my wife explaining the engine, the setup, and were wonderful to people with little engine experience... as was Gus, and Grace, and Chris Heintz... So, the plane is awesome as are the people, and we still have to wait a little longer for flight ccharacteristics. But I Am sure we can believe what he says...he is one of the good guys (as are the others mentioned)....I purchased my 601 partially completed from another builder, so ZAC got nothing from me but questions...and a refund request for a cowling for the 0-235...and they gave me a credit for the purchase price, and I purchased it from the previous owner!!! That is service!!! --------------------------------- ________________________________ Message 7 _____________________________________ Time: 01:05:02 PM PST US From: "" Subject: Zenith-List: N569Z Crash --> Zenith-List message posted by: "" I just wanted to let everyone on the list know that I am still alive and will fly again soon if the FAA will allow me to.

Many (and perhaps average people) try their best to blame someone else. Such as the fuel selector was improperly made so it didn't lock, ect ect ect. Thank you for the honest appraisal of your accident and the people that have posted in the past. You make this a better world and helps reinstate my faith in people. Glad to hear you are ok.

My DAR didn't have any problem with it. There is a different solution to your problem, however it is more expensive than your way and more permanent also. Have your fuel caps engraved by Aircraft Engravers. See our web page at http://engravers.net/aircraft/fuel_caps.htm. With some paints and most decals the fuel will attack them and they will be a constant source of maintenance and/or replacement. However, we engrave the text to .020" deep and fill them with a two part paint, then they are filled flush to the surface with a two part clear paint for a maintenance free labeling job. The price is $20.00 or $25.00 depending on what you want engraved.

I too survived a similar crash except it wasn't a homebuilt (C-185 on floats). I ran one tank dry and it quit too low to switch. Is the plane fixable or is it totalled? How far along are you on the 640?

Marking and drilling bottom side of nose skin - front spar rivet line: 1. How many rivets (if any) did you place I/B from NR #1 to the I/B edge of the Bottom Spar Angle? I can't seem to find any reference other than "Plan for a rivet at intersection of rib flange center line with rivet line in spar - A5 pitch 40" (Drawing 6-W-8) 2. How far out did you go O/B of NR#8? Again there's no guidance. Did you place the last rivet 10mm from the O/B edge of the spar tip and then pitch the rest at 40 back to NR #8 (also adding the 3 rivets on each side of NR #8)? 3. Did you find yourselves "adjusting" and compromising with the front spar rivet line. If I place the rivet line 10 mm from the aft edge of the nose skin then I'm really blowing the edge distance for the leading edge of the bottom rear skin. I've managed to keep a 2 x rivet diameter edge distance (10/32 or 8mm) but was wondering if anyone else experienced the same problem. My skins are cut correctly and the wing is jigged correctly. Thanks for any insight you can provide.

I'm thinking that even being able to switch tanks is unnecessary. If you read the NTSB reports, you see that lots of times after a crash they find that the pilot was on the empty tank, while the other tank had plenty of fuel. I'm fishing for opinions. I'm seriously thinking of direct runs to a small header tank on the firewall and all tanks with balance tubes between them would be the best bet. It would keep your weight even between both wings. Seems to me that it's just a pain in the rear with more things to go wrong. I'm beginning to think it's just one of those "we always done it that way" things with no real logic behind it. I have never in my 40+ years of driving run out of gas in a vehicle, why would I think I would in an aircraft? On one of my Gyros, I had two 11 gallon tanks, one on each side of the cabin with two 3/8 balance tubes between them and the bottom of each tank fed the fuel pumps. I always use dual pumps. They have moving parts, and things with moving parts fail at some point in time. I had a full length sight gauge on the outside so I could do a pre-flight and a regular electronic gauge on the dash. I never had a problem. Maybe there's something I don't know, but would like to know the thoughts you guys have. Unless some one can tell me why I must be able to switch tanks, I'm gonna box my switching stuff up and send it back.

You have an awareness when driving a car that you've been driving so many miles, that you start thinking it's time to fill up. If you keep that same awareness while flying, then this won't be a problem. Flying a plane is a lot like driving a car, although admittedly much less forgiving. BEFORE each flight, what happened to the idea of advance pre-planning where you figure your fuel requirements ahead of time? I've never left the ground on a cross country flight without having everything mapped out, nor should any pilot. No matter how you design your fuel system, there's no automatic, no-brainer way to make it foolproof. And by the way, I agree with the other person that admired the crash victim for being forthright with their mistake. So that others may learn....

However, the real bit of advice is that you can never go wrong adding an extra rivet where needed. So if the pitch doesn't work out per plan, then simply add another one (keeping minimum edge distances in mind of course). I used to rack my brain over the omissions of ZAC's plans, until I finally figured out and understood the concept of the whole thing. You'll end up making adjustments throughout your project when it comes to rivet placement.
