It's Alternative Engines Volume 2 by Mick Myal and it was ordered thru the Builders Bookstore. It covers a lot of Subaru cooling solutions that run the total gamut. It's very well illustrated and examines a multitude of homebuilt aircraft as well as historical evolved wartime liquid cooled designs. Of the automotive engines covered, a good many of the homebuilts are Subaru. In wing radiators and the airflow results are shown for a mulitude of variations from earliest to the latest modern applications. Several VW Rabbit radiator installations are examined, discussed and well illustrated for approaches that work best to improve cooling issues. This book covers redrives, mounts and systems in detail. For $43.00, I think it's a bargan and a very interesting read for the experimenter.

Hi Larry, You can pretty much put whatever date you want there, since as the manufacturer, you can declare any date to be the "done" date. (When is it ever really done??) One consideration about this date is if you live in a state that has personal property taxes on airplanes. This date MAY be used to determine when the taxable value changed from a pile of sheet metal to one of a functional aircraft. Id this is the case, you might want to postpone the date as log as possible (After phase 1?), but the DAR will probably want to see something there. Having said that, if you're that close to completion, you really should talk to the guy who will be your DAR about that ahead of time just to avoid any issues he may have. I've seen that some DAR's have particular issues they home in on - some insist that ELT be mounted in the rear fuse since forward ones don't survive a crash very well, some are particular on the lettering used for placards and markings, etc. Ask him is there is anything he looks especially for. Also, be advised there is a new application for airworthiness form that you will need, not one that you got out of a 2 year old packet. One DAR even insisted it be on a single sheet (both sides printed) instead of printed out from the web site on two sheets. You can go the faa website to see if yours is te current one, or contact your FSDO for a copy. Sometimes they want some things that are not in the regs, and you have a choice to challenge them or just give in. Usually, giving in the best idea since it is usually founded on a safety issue, and many things this way can be taken care of right away. If you want it to pass first time, though, I think the best thing to prepare is to talk to your DAR and ask how you can make sure you will have everything he wants to see. Ask him what things he made other builders change, and that will give you some idea. Hope this helps, Gary Liming ________________________________ Message 4 _____________________________________ Time: 08:04:01 AM PST US From: ZSMITH3rd@aol.com Subject: Re: Zenith-List: Data plate question --> Zenith-List message posted by: ZSMITH3rd@aol.com Larry, In 1999 I dated one in November, but the final inspectiopn was in December.

Question 1. Is it best to rivet the normal way from the outside and just let the rivet "tail" protrude into the cabin area floor or let the head be inside the cabin and the tail protrude into the outside bottom? Question 2. The next section 10 calls for leveling the rear fuselage along Ref. line A-E. Since the ref. line is a few mm below the top of Fuselage do you just use a string stretched along the side with maybe a line "string" level ? Thanks in advance for any help/opinions.

Otherwise I did whatever seemed best. Some rivets cannot be pulled with the fuselage sitting on a work table. You have to scoot it over the edge or turn it upsidedown. Therefore, the reason for my mixture since I don't have anyone to help manhandle the thing. As to the "Line A-B" business: I established that line per the drawings, lots of looking, measuring, etc. Since I had the whole thing up on a level table I also measured from the table top up to the "A: & "B" points just to check my string. I have one of those digital "smart levels" that I then used to measure several points and record them with a Marks-A-Lot right there on the spot. My floor, between the front of the seat and the rudder pedals is "plus 6 degrees". This made it much easier to rock the fuselage back in order to rivet under it and then return to the "A-B" level position.......simply rock it to +6 and move on. Hope this might be helpful.

It's best to run the fuel lines downhill from the tanks to the gascolater with no local low spots where water and sediments can settle out in the lines. The wing dihedral helps with this as the bottom of the tanks are higher than the cabin floor. My fuel lines run downhill all the way to the gascolater and then uphill all the way to the carbs. That way I only need to drain water at the gascolater and at each tank. -- Bryan Martin N61BM, CH 601 XL, Stratus Subaru. Airframe construction complete. Panel and engine installed.

I'd go with a L/R/OFF and not have a BOTH valve. With low wing a/c if you have it set to BOTH and one wing tank is dry you'll suck air and not get the benefit of the fuel in the other tank. Also, on the gascolator. I'd work hard to keep it at the lowest point in the fuel system. Putting the gascolator on the firewall means it isn't. Also, running the lines up to the valve would leave low points in the line that are undrainable. This is where sediment and water (frozen in the winter) can accumulate. I kept my gascolator at the lowest point and stuck my L/R/Off valve on the cabin floor. You can get an expensive Andair valve with an extension that would allow you to keep the valve low if you want the center console selector.

I'd have to agree with Frank. Not because I know, but because I put this question to Chris Heintz in the form of a diagram of my fuel system. The concern is that some inspectors will require that the two tanks be vented together if they are interconnected (via the BOTH position). That means you may need a vent line between the two tanks. The concern is in the case that one tank's vent line is blocked by an insect nest or similar. With the interconnecting vent line in place, both tanks are vented by the other tank's vent line allowing you to draw fuel from it. If you can't draw fuel from either one, you have a situation similar to what Frank described. It was clear to me that this advice was born of experience, not regulation. This interconnection could be difficult to route through the fuselage after the plane is finished if the DAR objects at inspection time. You might check with your prospective inspector now to see what they think.

Jack, the answers everyone has been giving you is all sound advice, but I'm not sure everyone (including me) knows your exact set-up. Do you have 4 tanks, or just 2? Is the console-mounted selector valve a 4-way, which means you can only select any one tank at a time? (no "both" setting?). In my situation, I have two tanks in each wing, with separate fuel lines for each one per ZAC's original XL plans. Because I installed them per the original plans, the fuel lines in the wings run downhill to the cabin floor...so I had to install 2 small gascolators on each side (instead of the one large gascolator as shown on the plans, since the selector valve would have to be after a single gascolator). From these small gascolators, each fuel line runs uphill to the 4-way selector valve on the center console, and from there on to the fuel pumps and carb. If you install the fuel lines per the newer auxilliary tank drawing 6-WKO-1 (4/03), then you won't need the smaller gascolators since the lines run a constant uphill in the nose ribs towards the fuel selector on the center console. (You would also need the newer fuel tanks where the inboard fuel tube is angled upward). Hope some of this makes sense, but email me off list if it doesn't. It shouldn't be this tough, if ZAC would have worked all this out looonnnggg ago.... Mike Fortunato 601XL wizard-24@juno.com
