I did further testing yesterday PM. On one side, I'm using a check valve in series with the pump on the other I'm not. The side that I'm not using a check valve in series is better (less back flow) than the one I am. On that side where I use a check valve in series with the pump, I have a back flow of about 0.8 liter per hour. On the other side, I was not patient enough to measure, but I would say .2 liter per hour. It seems that the side with the check valve is more noisy probably because the ball in the valve clicks at every pump cycle. It is surprising that I did not get any other comments on this post as this has been discussed in the past and those who wrote in the past now have experience with using the system.

Michel, I have left and right wing tanks joining at the center cockpit before flowing forward to the engine. I do NOT have a check valve between the two tanks - just one Facet pump in each line near the tank. Consequently, if I park the aircraft on a level surface for a day or two, any difference in the tanks tends to gradually even out. Also, I have to watch that I don't park the aircraft on an uneven surface when both tanks are full or one will flow into the other and cause an overflow. A very simple operational solution is that I select my fuel line valves OFF when parking at the end of the day. Otherwise I see no problem with just having the check valve function, imperfect as it is, in the Facet pumps. On a related matter - I was told that someone 'snagged' your fuel selector valves for not having a positive OPEN detent. I have the same valves and I have to disagree. Mine (at least) do have a positive open detent, but it isn't of the same magnitude as a $150 aviation valve. I think it's adequate, but just to be extra-safe, I intend to add a mechanical 'guard' that will prevent accidental movement of the valve selector. fwiw...

I did not get snagged as this was a pre-cover inspection (which by the way I proudly passed with no snag :-), but I got a warning for the final inspection. It seems that these valves are evaluated pretty inconsistently. The week before me, a friend using ball valves (those with a red handled) passed an inspection without any comment on his valves (same inspector). I see what you mean with the positive detent on our valves... they appear to be spring loaded so they would tend to stay full open when they vibrate (in my mind). This was not obvious when the inspector came as the valve never saw any liquid.. it is more obvious now that I tested them with fuel. I'm gonna remove the check valve I added as I think it provides more potential for problems than solutions.

I plan to determine the need for pulleys or re-routing while the aircraft is "in service" as I don't believe that any wear will be fast enought to cause an unsafe condition before I can catch it. In fact, when I asked Nick Heintz about it, he said that the factory demo has shown no fairlead or cable wear at those points.

The same goes for the rules on control system pulley diameter. Of course, the sharper the bend the sooner the cable strands will fatigue and break.

So far the best I can get is a gap at the leading edge bend of around 15mm. This was with the use of considerable force applied by a tie down strap. I don't want to use any more force for fear of bending the LE skin. I checked the profile of the LE skin against a nose rib from the other wing and it is OK. Any suggestions?

Looking a few pages ahead to the installation of the fuel tank I see I'm gonna need to buy a few more items I don't have yet,such as a flycutter. I know where to get a flycutter but can anyone tell me where to get the following: 1. Manual says to put some "fuel resistant adhesive" on the threads of the drain and outlet.I know about teflon tape and pipe dope used in regular water plumbing but I don't think they are fuel resistant nor adhesive. What is this stuff and can i order it from AC Spruce? 2. Also, is there some type of locktite stuff to put on the bolts that will be inside the wing such as the front strut bolts? I know about locktite but it might melt the nylon in the nut? Is there something else that is used for aircraft bolts? Available at AC Spruce? 3.I looked through the archives before I started on the wing to see if there were any good ideas on things to add or cautions to watch out for on building the wing. One idea i liked and added to my wing was the "false ribs" or" skin stiffiners" to help against oilcanning.Does anybody else have any other ideas or cautions they can suggest that would be good to add or not to the wing before I close it up? Thanks for the help and hope to see some of ya'll at Sun n Fun! Just driving down with the family this year but hopefully can fly down next year!

Either I pulled it up to the top side with a small gap at the bottom near the leading edge, or vice-versa. I finally decided to do the best I could, with the thought that I'll close the small gaps with filler later on.

Maybe I got a bad pair of fiberglass tips. I don't want to drill and regret it later. I'm at the stage where I've rough cut the LE skin O/B end and everything is clecoed together (except the fiberglass tips). There is no way I can close the gap at the leading edge without something bending or kinking. The tie down was applying a lot of force. I looked at it again today and I've sent an email to Nick @ ZAC. I can sight along the NR tips and hold the fiberglass tip in position at the correct angle. It just doesn't line up. The radius of the leading edge is too big. How did you install yours? Did you have the LE skin open, rivet the bottom, then close the skin over the NRs and the tip? If so, how did you measure the position of the tip? Looking forward to seeing the photos.

I can't remember exactly how I did it, but I know that four hands were used (my father in law helped me). Straps are not needed as the wing is already closed.

It was hard to visualize how it would fit. I just put it aside and got to work on the main part of the wing. I didn't look at it again until I had all the skins riveted down to the skeleton and most of the trimming done on the o/b end. I used the upper and lower edges of the 45 cut on the spar tip as references and marked off the measurements from the drawings as a starting point. I roughed in a trim line and then made my first cut well outboard of this line. I started gradually trimming off the excess using a 2 by 4 foot sheet of paneling as a reference plane to get within a few millimeters of where the final edge would be and then took off the rest with a file. I would stand directly in front of the wing and sighted across the cut end to check for any deviation and then go back to filing. It was slow work but in the end I could put that sheet of paneling flat on the on the cut off end and make contact all the way around. After the o/b end was trimmed to its final shape it was much easier to see how the tip would fit. At that point the tip fit the opening fairly well. I Don't recall any gap at the nose of the wingtip but there may have been some gapping towards the rear but the part flexed enough to pull up tight when it was clecoed in place. By the way, don't rely too heavily on the measurements for the o/b end cut from the drawings. Consider them to be a rough guideline. Cut well outboard with your first cut and work your way in. -- Bryan Martin N61BM, CH 601 XL, Stratus Subaru. Airframe construction complete.

Here's a trick - try heating up the fiberglass wing tip with a heat-gun ( go slow an use low temp to start ) as the fiberglass heats up can manipulate it ( wear heavy leather glove or oven mitt ). I did this, and it worked fine. I also took an extras step and made a plug from the outline of the sheet metal. I stuck the plug into the fiberglass tip as it cooled to keep it's new shape. If the parts are really bad, just call Zenith. I have had no problem returning parts for replacement.
