Joseph, as Michel has already explained, those angles are "closed", i.e., <90
degrees when measured inside.
As for the 3.5 vs 5.5 degrees: I didn't spend much time on it. For one thing, I
can't get 0.5 degree precision.
Remember, it's not a fighter jet.

Joseph:
I am plans-building the 601XL and I feel your pain. I have found many
builder's web sites with photos tend to clear up my questions about parts
making and assembly. Also, the Zenith web site (www.zenithair.com) has a
builder's site that has the new, updated manuals in color that can clear up
some of your questions on which way to bend a part. Zenith doesn't say much
about the builder's site when they send you the plans but if you call them
they will give you the password.
I can send you several links I have found if you email me off-line. Also, I
have built several parts for the tail section and you can see them on my web
site: www.cooknwithgas.com.
Good luck,

--> Zenith-List message posted by: "Joe Kerr" <jkerr@pcweb.net>
Greetings-
Here's my first question to the list after lurking for a year. I just
received my 601XL plans and am evaluating scratch building vs kit purchase
vs a combination of the two.
Perhaps a newbie question, but I can not find the answer in the archives and
it did not come to me after studying the plans for a couple days. On
vertical tail spar 6T4-4, the plans say the bottom side is bent 5.5 degrees
open, but the double angle 6T5-5 which fits inside the spar looks bent in
the direction I would call 'closed' by 5.5 degrees (resulting in the 84.5
degree bend indicated). I hate to start thinking the plans are wrong when I
am so new at this, so I thought I'd ask. Should the plans say 5.5 degrees
closed for the spar bend rather than open? It seems the doubler would then
fit inside.
Part two of the question. The plans call for the bend at the top of 6T4-4
to be 3.5 degrees closed. If this is the case, does this mean the bend
angle of the side would gradually open two degrees starting at the point
where the spar doubler ends (approx 900 mm from the bottom of the spar). Of
course, if the plans said the top angle should be 5.5 degrees closed rather
than 3.5, and the 5.5 degree open bend at the bottom should really be 5.5
degree closed, then it would be a consistent bend angle from top to bottom.
So, either the plans are wrong in two places in the first place I looked at
closely, or I'm really missing something basic and definitely need the kit
with preformed parts. Thanks for any help.

The information in the email sent by Weston is very
useful. The following information is provided based
upon an incident that took place last December.
A friend was over the Midwest flying his family back to
Virginia in his homebuilt (very popular brand kit but
not a Zenith). He noticed a worsening reduction in
power that he was unable to reverse while flying
through a snow storm (so much for weather forecasts).
The engine quit. He landed the airplane (in the snow
storm with 1/4 mile visibility) in a field a few miles
short of the runway at an Air Force base. Everyone was
safe and the plane received only minor damage (wheel
pants). Upon checking for the cause, he discovered the
air filter was surrounded by snow/ice. The application
of carb heat put the heated air just behind the air
scoop and in front of the air filter. There was
insufficient hot air to melt the ice and snow, thus
cutting off the air supply. The airplane designer used
the same design on all of his designs.
Lesson: Route the carb heat supply to be after the air
filter. You will find this design on production
airplanes. It guarantees a supply of heated air into
the carb even if the normal air intake is completely
blocked.

Subject: Zenith-List: 601XL/3300 Firewall Forward Kit
--> Zenith-List message posted by: "Weston & Judy
Walker" <westonjudy@earthlink.net>
I am about to purchase a Jabiru 3300 and a firewall
forward kit for my
601XL. I just discovered the firewall forward kit that
ZAC sells is
different from the one Pete sells at Jabiru USA Flight
Center.
According to Pete, here are the main differences:
1. Prop. ZAC uses Sensenich. Pete supplies GT and
claims better speed
and climb, better fuel efficiency with GT.
2. Location of oil cooler. ZAC on the side. Jabiru
lower center in
front of vent; claims better cooling.
3. Cowls. ZAC made by Skyshop, fit on inside of front
skins; Jabiru
from Jabiru in Australia, fit on outside of front
skins.
4. Carb heat. ZAC=92s filter is bypassed when carb heat
supplied; Jabiru
filters air either way.
Does anyone have any good/bad experience with either of
these Firewall
Forward kits? Any other pointers?
Thanks for your thoughts.

Hi all, Looking for a 601 un-completed kit for sale.
Must be a complete kit. Will look at kits with FWF's too.

--> Zenith-List message posted by: Michel Therrien <mtherr@yahoo.com>
Hi list,
I'm thinking about the exhaust system for my 601 and I
have a few questions.
1. How does the Stratus muffler system performs in
terms of noise reduction and weight?
2. Does anybody here has another exhaust installation
for an EA-81 engine and could share a bit about the
design and performance?
Thanks!
Michel

Michel,
Tony Bingilis's book Firewall Forward has a very interesting Swiss Muffler
described on page 111 that intrigues me. It would move the CG back a little
and it's reported to comply with Swiss regulations on aircraft noise.

I thought seriously about that for a while, but I
can't find the SS mesh nor the 4" aluminum tube.
