Hi Dave , I wrote this big long letter, and after an hour of work I
deleted
all of it, their was nothing in it that I have not said before, I am
writing
to invite you to the www.zenith.aero <http://www.zenith.aero/> list. It
is
a better format then the Matronics list in my opinion and has over a
thousand members already. It allows blogs and is a great resource of
information and interest. Since going to www.zenith.aero
<http://www.zenith.aero/> list I do not keep as close a watch on the 6
Matronics lists that concern Zenith designs, I enjoyed it when it was
only
one list, not 6 different ones. Plus for you I have set up a Canadian
Builders section that deals with Canadian content for Zenith Owners and
builders, gatherings and notices of events, come over and have a visit.

HI Sabrina, congrats on the bike, it is an adventure only surpassed by the
airplane. Over the years I have taught the Motorcycle safety course many
times and it is worth every cent you can put into it. However, do not stop
there, the first course uses basic bikes to train you on and they are well
suited for learning the basics. I advise you to find out if an advanced
course is available.
After your basic course is done then ride for a couple of months and enroll
in the advanced course. In this, you will be using your own bike to perform
maneuvers. This makes a huge difference, I have taught many people who did
quite well on the basic course, but had difficulties in the advanced course
with their Goldwing. Knowing the limits and handling of the bike you ride is
extremely important. Over the years the only bike I put down was a Yamaha
FJ1100, but that was during a race at Shannonville and I slipped out in the
3rd bend( wear full leathers, or minimum jeans and always wear gloves,
helmets are mandatory in Canada).
My Goldwing has gone down the road several times with the rear tire ahead of
the front due to ice or oil and over the years I have hit several animals
like deer, Clydesdale horse, gator, armadillo. All of which I can refer to
the lessons learned and taught at the safety course, with several hundred
thousand miles on my bike it has still never left the rubber.
I can add several pages of advice here but all will be taught to you at the
course. Enjoy, be safe by being alert and ahead of the drivers around you
and keep the rubber down.

My two cents' worth:
I don't ride a motorcycle but I do ride a bicycle every day to and
from work, rain and shine, daytime or dark.
Based on that (harrowing) experience, I will posit that, if a
motorcycle safety course is available in your area, you should take
it.

| Subject: | Off Topic - Motorcycle vs. Clydesdale |
4 am I was riding the wife's Yamaha Venture Royale going up a 4 lane highway
( 2 on each side separated by a grass median )all alone, I was tired and
traveling at 60 mph in the left lane close to centerline, when out of almost
no where there is this huge horse in my lane. I was able to bank the bike
quick enough to go just pass the ass of the horse but my lower cowling and
hwy peg caught the rear leg of the horse and the bike did a little rear tire
dance. This was the lucky part!
Due to the bike getting swung around a bit and my correction for the force
applied I found myself in the opposite lean returning to the center of the
lane I had just left, when out of nowhere again the face of a second horse
passed over my right shoulder, this was a smaller horse and was following
the Clydesdale. If it wasn't for the swing from hitting the first horse I
would have impacted the second dead on from my maneuver to miss the first
horse.
Shaken I got to a pay phone and called the police, (didn't have a cell in
the 80's) and we tracked the horse to a farm. The story I was told a few
days later is that the owner of the horses had moved from the farm in which
we found the horses to a new one and the horses got out of the new pen and
headed for the old farm. THE Clydesdale was treated for a cut on its leg and
recovered, so I was told(dam strong horse as it bent the crash bar that the
Highway peg was attached to) the farmer was not charged for the horses
escaping. I went on with an amazing story to tell my students over the
years. Nevertheless, I still can see that night as if it just happened.
Funniest part is that I can still see the details of the second horses brown
head with the white spot in the dead center running down it's nose. I swear
to god that when I snapped my head as I saw the second horse pass my right
mirror it was not further then a foot from his nose to my nose. I didn't
even have time or had fully recovered from the correction to look back at
what the hell had just happened when the second horse appeared beside me,
likely another lucky break.
Even though this Is one of those memorable stories that we all have from our
past, it is by no means my only adventure, I have hunting stories from my
past that have chilled people. Yes I used to also instruct the Bow Hunters
Safety course. Every Spring I would take a student on there first Bear hunt
with Bow and Arrow. But that is for a campground and a fire.

| Subject: | 601XL Fuel System Questions |
Hello Listers:
I have a question to ask the more experienced builders of the group regarding the
fuel tanks & plumbing of the fuel syatem on my 601XL.? I am working on the
right wing so i have lots of opportunity to make changes - since everything I
am questioning hasn't been built yet !
I am considering using a return line to the tanks and a restrictive orifice (a
'controlled leak') at the carb to maintain fuel flow PAST the carb to reduce and
possibly eliminate the chance of vapor lock in my plane.? With regard to changes
to the original Zenith design, I see this would require:
a T-fitting and orifice at the carb, return lines to the fuel selector valve, a
new fuel selector valve (VERY EXPENSIVE) with a return segment, return plumbing
to each tank, and tank modifications to accept a fuel line.? I'm not a welder
so I would need to find one to modify the tank, as well as getting a proper
fitting to weld into the tank.
My questions are many: is all this worth it?? As I see it, yes.....ALL modern?automotive
designs incorporate a return line to the tank (yes, I know they are
fuel injected, but that's a whole other issue).? There has been some discussion
regarding fuel selector valves: in that they represent a single point of failure
potential.? Would on-off ball valved be a better solution?? Please...I'd
like opinions on this.?
My thoughts are to use rigid tube in the fuselage...does anyone have a primer or
a good website on the proper way to bend rigid tube and the best way to anchor
it?
Speaking of primers - this time engine primers:? I recently purchased an engine
peimer that is tapped to accept 1/8 NPT pipe fittings.? I am looking for 2 fittings:
1/8 male NPT to 1/4" barb, and 1/8 male NPT to that I believe is 1/16" copper tube
compression which goes to the primer nozzles in the intake manifold.? Where
do?I get these tiny fittings ?
ACS had very little to offer.
Thank you in advance for your help.? I have been at a standstill for a long time
about this and I welcome all thoughts and opinions.

| Subject: | Re: 601XL Fuel System Questions |
Tracy,
In my not-so humble opinion, you are WAY overthinking this.? The 601XL is a very
simple airplane, comparatively.? It is not a super blow-down high speed pressurized
twin with fuel injection, constant speed props and many fuel tanks.? The
system ZAC envisioned for the airplane is entirely adequate. ?? All of the
things you are contemplating just add complication and more points of failure;
making building more difficult and time-consuming; and adding unnecessary inspection
and maintenance chores.
My 601XL has the ZAC
supplied rubber hose from the tanks to the dual stick bulkheads and
braided 6AN line from there to the selector valve, fuel pumps and
carburetor.? I have a Corvair engine with a MA3-SPA carb, thus no
primer is needed - very simple.
My advice: KISS and keep building.

Sabrina,
Like Mark said, take the advanced course. I had been riding many years before
I took that course and wished I had done it when I was much younger. It really
teaches you how to control the equipment in ways I had never thought about.
I am a much safer rider now as the result of the advanced course.

Craig-
1. I have a belly strobe rather than tip strobes.
2. If I do go with the wing installation, I'll restrain where I can and
add additional shrink wrap on the outside of the cable to those areas of
possible abrasion.
I had a plan B until I mounted my solenoid on the tray I put in mounted
behind the seats. I could move the solenoid, but then I'll eventually be
installing the access steps and that will probably screw things up. I could
solve the problem by eliminate putting on the access steps yada, yada, yada.
If the remote compass isn't happy in the starboard outboard wing, it's
not going to work.

Homebuilers are nothing if not ingenious and adaptable, so I bring this
to youse. I need an idea.........I'm having a tough time trying to bend
some 1-1/8 aluminum tubing to make the intakes on the Corvair heads. So
far, I've fabricated the flanges, but bending the tubing into tight 90
degree curves has me stuck. My local muffler shops have tried, but
without the exact size blocks, they can't get the bends right without
crushing the bend somewhere. I've looked for conduit benders, but none
are the right size. As a fallback I've thought about using a wall pipe
from Ace Hardware's plumbing department, (pretty chrome) but it's thin
wall brass, and likely to crack from the vibration. Any ideas? How'd
everybody else do it?
Thanks,

I'm sure others will give better answer, but the usual way is to pack
the pipe with sand before bending. They even do this on heavy wall (6
inch wall thickness) steam pipes.

You could build your own bending blocks out of hardwood and use a
hydraulic press to do the bending. If you don't have access to a
press, it wouldn't be too hard to build one out of a large bottle jack
and a steel frame. I've heard that if you fill the tubing with sand
and seal the ends, the tubing won't crush when you bend it. I've never
tried this, just kicking around some ideas.

FWIW-
According to my whiskey compass, the best place to level and avoid
magnetic interference between the D-100 and remote compass sender on my
HDS is the baggage shelf. Nothing else comes close to being acceptable
unless you used non-magnetic cables. According to Dynon, you still have
to be careful because some stainless will still cause deflection.
I thought things were solved re: putting the sender in the wings
until Gig reminded me of the +/- 1degree sender/receiver alignment spec.
In flight wing deflection would bust it.
On my project I don't think I can do any better. If the installation
doesn't work out so be it- I'll carve a hole in my panel, mount my
whiskey compass and add another 3lbs.

Is the +/- 1 degree requirement on all three axis? You could try a
real-world test: plug the sensor into the D-100, simulate the roll it would
see as the wing flexed and see if it actually affected the heading display.
Maybe RV's are stiffer because I'm pretty sure I've seen the sensor in their
wing tips. What do they say on the Dynon forums?

| Subject: | Re: 601XL Fuel System Questions |
Modern auto designs have return lines to the tanks BECAUSE they are
fuel injected, and for no other reason. The the fuel pump is in the
tank and pumps high pressure fuel to the engine. A fuel pressure
regulator maintains a constant pressure for the injectors, a certain
amount of fuel must bypass the regulator for this to occur. This low
pressure bypass fuel is returned to the tank. If you don't have a fuel
injected engine, installing return lines to the tanks is going to make
your system way more complicated than necessary.
Vapor lock is a phenomenon that occurs at the fuel pump, not the
carburetor. It occurs when the fuel at the inlet of the pump is
vaporized. The fuel pump is designed to pump liquid, not vapor, so the
fuel stops flowing. Putting an orifice at the carburetor won't help
this situation. Vapor at the carburetor is not a problem as long as
fuel is still flowing up behind it to push it on through. The way to
prevent vapor lock is to make sure that the fuel pump always gets
supplied with liquid fuel. Two things can vaporize fuel: suction and
high temperature (or a combination of the two). Sucking fuel uphill
from the tanks in a low wing airplane with a fuel pump mounted on a
hot engine block in a hot engine compartment is one good way to end up
with vapor lock. Especially if you are using auto gas. Avgas is more
resistant vaporization. The most likely scenario for vapor lock is
fuel in low wing tanks, pump mounted on the engine, hot day, full
throttle and nose high attitude. In other words, right after takeoff.
Your fuel pump should be located near the low point of the system so
it always gets gravity feed from the tanks. Just ahead of the
gascolator is good. Some people have put the fuel pumps right at the
outlet of the tanks. this also works well but puts pressurized fuel
through all the lines in the cabin. You should avoid having anything
upstream from the pump that can cause a significant restriction to
flow, this will cause a pressure drop and increase the risk of
vaporization. If you have an engine mounted mechanical pump, you
should have an electric boost pump mounted ahead of it and use it for
take off to make sure the engine mounted pump always gets liquid fuel.
I have two ball valves in my system, one for each tank, mounted on the
floor ahead of the spar on either side of the rudder cable tunnel.
That was the way the system was originally designed. It's simple,
effective and inexpensive. I never saw any reason to put a fancy,
expensive selector valve in there. The valves feed fuel into a tee
fitting at the gascolator and I have two fuel pumps in parallel on the
floor just ahead of that. The fuel lines slope downhill all the way
from the tanks to the gascolator and the pumps are at the same level
as the outlet of that. Then the fuel line slopes uphill to the
carburetors. I've never had any hint of a problem with vapor lock with
this setup.
I used 3/8" O.D. 3003 aluminum tube from the tanks to the valves.
Mainly because hoses will eventually have to be replaced and I didn't
want to have to dig into the wing root area to replace fuel lines. I
used hoses everywhere else. I was planning to use aluminum, but the
hose was easier to install and it will be easily accessible when it
comes time to replace it.
For your fittings, you have to remember, hose fittings are sized by
the I.D. of the hose and tube fittings are sized by the O.D of the
tube. So if you are looking for a fitting for a 1/16" I.D. tube, it
will be listed under 1/8" O.D. fittings. Here's your hose fitting:
AN840 HOSE NIPPLE, PIPE THREAD
http://www.aircraftspruce.com/catalog/hapages/an840.php
There is an error in the above web page, the column that reads Tube
O.D. should read Hose I.D.
For your tube fitting, maybe this is what you are looking for: primer
fitting AN780-2, AN800, AN805
http://www.aircraftspruce.com/catalog/hapages/primerfittings.php
Although I think this is a flare fitting, not a compression fitting.

Paul;
I have made a few intake manifolds before. I purchase 45, 90 and 135 or 180
degree "mandrel bent" tubes in the diameter I need, cut them to fit, then
weld
together and grind off the seams. The "mandrel bends" bending technology
makes for smooth curves without kinks.
Do an internet search for mandrel bends and you will find lots of suppliers.
The aluminized steel is easy to wield, but not as light as aluminum.

Many carburerated cars from the 60's and 70's were equipped with fuel
return lines to prevent vapor lock. They used an inline fuel filter
between the pump and carburetor. The filter had a third fitting
(undersized) that returned fuel to the tank, The filter that GM used
is still available from NAPA.

I use CAD to draw the intake and then went to my local Mandrel bender (In Australia)
and he made the intake exactly the same as the one WW sells. They cost me
$100 each including the stainless steel tubing.

| Subject: | Re: 601XL Fuel System Questions |
And they generally had a mechanical fuel pump mounted on the side of
the engine. The bypass line probably helped keep the pump and fuel
cooler by bleeding off some of the fuel heated by its trip through the
engine compartment. Some airplanes have bypass lines for a similar
reason, they also generally have mechanical fuel pumps on the engine.
Modern autos with fuel injection have electric fuel pumps submerged in
the fuel tank, which makes vapor lock impossible. An electric pump
located in a cool area with good gravity feed will also prevent vapor
lock. It's also a whole lot simpler than all the extra plumbing. If
you do have an engine mounted pump, using fire-sleeve on the fuel
lines also helps.
