Re: Jim Patillo fuel system

Hi

G-BXOY has the top mounted flush filler, works great. Jims idea good too. Mine has a stand pipe directly below the filler cap with hole cut at top to work as standard standpipe (overflow) all within the header. Only thing I would change be to make the stand pipe from top to entery into main lager diameter or split to allow air to escape quicker to speed up filling. NB the fuel system is ram air presurised so must be leak free. There is an advantage of top mounted filler if the cap is left of it's you know on climb out. I sure would love to see the picks of Jims( Sam or Jim any chance of posting then or sennding off line?) If any one asks I can post pic of header tank before glassinig in. Clive ......GOBXY

LS1 Foam Layout. . .
quickheads
You've got to love QAC. . .
I have been working with a set of LS1 templates and trying to figure out how they get lined up on the ends of the foam blocks. The LS1 instructions say to use the same block sizes called out in the Q2 plans, but the angles generated don't really match the sweep of the LS1 canard. So how do you know where to place the templates horizontally on the blocks. Also, on page 3-6 of the Q2 plans it calls the "level Lines" drawn on the templates "Water Lines" does this mean that the "Level Lines" on the templates are placed at the same level vertically on the ends of the foam blocks as well as being "level"? Or is this just an artifact from the VariEZ plans that got copied and pasted into the Q2 plans? I'm guessing that you Q-200 (and Q1 LS1) guys had a lot of futzing around to do in order to get your cores to fit on the spars. Let me know how you did it! I appreciate your experience. Thanks, Dan Yager QBA Editor www.quickheads.com

Fuel lines, was First flight
In complete deference to my friend John, whom I know is an expert in
urethane and knows more about the subject than the bare inkling that I will ever have, I have been using urethane tubing with great success for most of the life of my Q-200. Maybe it's the formulation that makes the difference. I started out with Tygon, which was better then the original vinyl tubing that QAC supplied. The Tygon was okay, then I stumbled across this stuff called *Tygothane, *which is much better. I get it here: http://www.mcmaster.com/#tygothane-c-544-a-i.b.-tubing-and-tygothane-hose/=d22kke I think Wicks and Spruce carries it, also. I like it because is has a smaller OD than the rubber, is easy to work with, and I can see the fuel inside. This stuff is really tough and abrasive resistant and holds up to 100LL for a long time. I seem to change it out every 5-7 years for no other reason than to be on the safe side. Just my experience.

I would use rubber tubing instead of urethane tubing for fuel lines. We have seen some bad instances here in Australia of urethane fuel tubing degrading ( hydrolysis) and fuel sloshing around the cockpit of a Glassair 3 in flight.

Re: First flight
dkeats <dkeats@...>
Sanjay----- On my airplanes I use automotive rubber fuel lines. They don't
harden and last forever. On another note regarding header tanks. On the Dragonfly we leave the fuel pump on all the time and then the header overflows and feeds back to the main. When I turn on my master, my pump is also on. No separate switch to forget. You may have to put a small restrictor in the line if the pump is pumping faster than the gravity return, but this system has worked great for me for twenty years. Canada Chris

Since you will service the fuel filter regularly, I would consider changing
the fittings so you have a flare fitting on each end of the filter. It won't take many servicings before you will say "I'm glad I did that"! Barb fittings are OK with rubber fuel tubing, but urethane gets hard and not really reusable in a short time. It remains strong, but stiffens. Rick Hole N1711Q Engine is running!

Re: Jim Patillo fuel system
Hi Jay,
toggle quoted messageShow quoted text
My fuels system is a one off. So here goes. The header tank does not go fully across the fuselage like plans built tanks. It was made to fit to the right side of the radio stack centered in panel)and gos to within 2" of the firewall. It is about 9" tall and holds 5.5 gals. (I did this to offset the fuel weight to the right when flying single). It's accessed from the top as you saw in the picture but the picture is a little misleading. The fuel cap opening on the top of the fuselage is directly in front of the passenger. All my fuel supply lines from pump to the header, through the shut off valve to carb are 3/8" stainless steel w/fittings. I do not like plastic. I have no site gauge but instead have two fuel guages and a low level fuel and light alarm. The main fill tube is 2 1/2" dia. steel and runs through and exits the header to the right side of passenger leg at the bottom of the tank. The connection from header tube to main tank tube is 2 1/2" Goodyear Aircraft gas line. The fuel fill tube is recessed about 3/4" below the bottom of the upper fuselage with some small 3/8" holes around the perimeter. This allows me to quickly fill directly into the main tank or the header. The steel tube is grounded to the ground buss. I have no gascolator! The fuel cap assembly is aluminum (grounded as well). I've never had any fuel leaks anywhere but did replace the fuel cap gasket once because of an air leak (created lower head pressure than needed). Hope this helps. Regards, Jim Patillo N46JP Q200

I appreciate your insight and can imagine what was running through your head when the fuel was pouring over your panel!. I am doing a couple of things that should prevent anything like that occuring. 1. I am building the tanks separately and pressure testing before they go into the airplane, and 2. my canopy opening is a set of gull wing doors, with the forward 1/3 of the original Q-2 canopy permanently fixed and glassed to the fuselage in front of the door openings, kind of like a more curvey version of a Globe Swift cockpit entry. Any leakage would have no chance of coming under the forward edge of the canopy because it is integral to the airframe. Also I long ago made the choice NOT to use any of the more questionable materials (like PVC and the plastic screw-on cap assembly) so I will stick with tubing materials, caps, fittings, and practices that are designed to aircraft standards.
