(Afterfxllc@aol.com) ________________________________ Message 1 _____________________________________ Time: 03:27:04 AM PST US From: David Downey Subject: Re: Zenith-List: Re: 701 unusable fuel I am not familiar with the 701 but am planning to install a baffle plate withthe one way swinging flap/check valves in my XL tanks. These are used extensively in large(er) jets to persuade the remaining fuel volume to remain inboard. Chuck, Mine are the same measured at 42.5 litres aside = 10.86 US gal each. I have unported the outlet when running off the tank in nose low and wing down attitudes where the fuel level was lower than 1/4, so I am cautious about feeding off the one side if the level is less than about 12 litres (3 gal) and switch to both for landings. I have cruised on one tank down to 1/8 without problems. The 5 times the engine shutdown were all during manouvers with lots of wing down nose down descent, and it recovered when the I levelled out, after a delay maybe 20 seconds. In some cases I switched tanks. Have not encountered this in normal landing approaches, but nowadays I select both for landing with low levels as an undershoot is not a satisfactory option. Suppose you could add a forward outlet port and tee it lower down like some Cessnas, or make a larger gascolator Zenair style as its like a little header tank ( I have the ACS type ) Ralph -------- Ralph - CH701 / 2200a Read this topic online here: http://forums.matronics.com/viewtopic.php?p=120395#120395 Dave Downey Harleysville (SE) PA Zodiac 601XL/Corvair? --------------------------------- Building a website is a piece of cake. ________________________________ Message 2 _____________________________________ Time: 03:29:19 AM PST US From: David Downey Subject: Re: Zenith-List: Nylon Conduit Routing in Wing This reply is not meant to replace the call to ZAC but a 1" hole at that location, if made with uniform circularity and with a polished edge should be invisible to the structure. If concerned, flange the hole 1/4" x 45. Working on wiring up my left wing (601XL) and I bought this nylon wire conduit from the Van's site. I'd like to keep it out of the wing locker area if possible and also clear of the two aft rear rib holes for the aileron cables. I'm thinking of routing the conduit at the point recommended on 6-LLO-1, 480mm aft of the spar and 40mm down from the top flange of the rear rib. See the pic attached. My question is will this area support a hole large enough for my conduit (about 7/8") without negatively impacting the structure of the rear rib. I may call ZAC tomorrow to get their input, but I'm sure someone has been down this path before. Thanks.

This need is for completely different reason. Does anyone know if the coordinates for that airfoil are in Ribletts book? I hate to spend $20 for something that I believe I already paid ZAC for... As I recall having layed out the forms, the rear rib line becomes a straight line towards the rear. If you are using a cad system maybe try placing the radius of the rear flap/aileron at the correct distance/orentation from the spar and join it to the rear ribs using straight lines to that radius in 3D space. I know nothing about designing airfoils so. . .

Since I don't plan on removing the wings I don't need the quick release feature. Has anyone replaced this fitting with something else? I am thinking about another rod end bearing and a bolt, perhaps.

He flew his first without pants and checked speeds in various configurations. He then added pants, and gained 10 knots in both climb and cruise. We have not flown ours without them, so can't give you a direct comparison with the 601. We had a problem checking air pressure and adding air, so we Dremel'd out a curve on the valve side of each wheel. Works fine, and looks ok, too.

This is certainly a helpful group and I'm glad to be in this builder community. I did call ZAC today. Advice was that maybe my 7/8" conduit was too large for what I'd be running thru it. Zac takes the approach of bundling the wires and pitot tubes together with zip ties and routing thru the same point in the rear ribs, but with a hole that's a half inch in diameter. They recommended keeping the edge of any hole in the rib at least 20mm from the lightening hole and top flange.
