Dear Lister,
Please read over the Zenith-List Usage Guidelines below. The complete
Zenith-List FAQ including these Usage Guidelines can be found at the
following URL:

Thank you,

******************************************************************************
Zenith-List Usage Guidelines
******************************************************************************
The following details the official Usage Guidelines for the Zenith-List.
You are encouraged to read it carefully, and to abide by the rules therein.
Failure to use the Zenith-List in the manner described below may result
in the removal of the subscribers from the List.
Zenith-List Policy Statement
The purpose of the Zenith-List is to provide a forum of discussion for
things related to this particular discussion group. The List's goals
are to serve as an information resource to its members; to deliver
high-quality content; to provide moral support; to foster camaraderie
among its members; and to support safe operation. Reaching these goals
requires the participation and cooperation of each and every member of
the List. To this end, the following guidelines have been established:
- Please keep all posts related to the List at some level. Do not submit
posts concerning computer viruses, urban legends, random humor, long
lost buddies' phone numbers, etc. etc.
- THINK carefully before you write. Ask yourself if your post will be
relevant to everyone. If you have to wonder about that, DON'T send it.
- Remember that your post will be included for posterity in an archive
that is growing in size at an extraordinary rate. Try to be concise and
terse in your posts. Avoid overly wordy and lengthy posts and
responses.
- Keep your signature brief. Please include your name, email address,
aircraft type/tail number, and geographic location. A short line
about where you are in the building process is also nice. Avoid
bulky signatures with character graphics; they consume unnecessary
space in the archive.
- DON'T post requests to the List for information when that info is
easily obtainable from other widely available sources. Consult the
web page or FAQ first.
- If you want to respond to a post, DO keep the "Subject:" line of
your response the same as that of the original post. This makes it
easy to find threads in the archive.
- When responding, NEVER quote the *entire* original post in your
response. DO use lines from the original post to help "tune in" the
reader to the topic at hand, but be selective. The impact that
quoting the entire original post has on the size of the archive
can not be overstated!
- When the poster asks you to respond to him/her personally, DO NOT
then go ahead and reply to the List. Be aware that clicking the
"reply" button on your mail package does not necessarily send your
response to the original poster. You might have to actively address
your response with the original poster's email address.
- DO NOT use the List to respond to a post unless you have something
to add that is relevant and has a broad appeal. "Way to go!", "I
agree", and "Congratulations" are all responses that are better sent
to the original poster directly, rather than to the List at large.
- When responding to others' posts, avoid the feeling that you need to
comment on every last point in their posts, unless you can truly
contribute something valuable.
- Feel free to disagree with other viewpoints, BUT keep your tone
polite and respectful. Don't make snide comments, personally attack
other listers, or take the moral high ground on an obviously
controversial issue. This will only cause a pointless debate that
will hurt feelings, waste bandwidth and resolve nothing.

Someone else on the list a while ago mentioned he put in verniers on
both sides but on the passenger side he removed the locking insert so
it would move freely and not be able to lock.
In any case it appears that an ACS750 vernier is probably my best
bet. Considering I have the standard ZAC throttle linkages (works
fine other than the throttle creep) how would I go about attaching
the end of that to the rod on the linkage? Anyone have any pictures
of an adaptation?
I flew the plane for about 45 minutes last night and the temps are
holding as reported yesterday. I stil have a heavy left wing and my
arm got tired of holding the stick to the right. I dropped the trim
tab on the right aileron down a bit but perhaps not enough. Another
person mentioned he thought I didn't have enough down-travel on the
tab to be effective.

but I am confident that it will work. I did increase the length of the arms in
order to get more travel on the cockpit throttles. Picture on page2 at:

Fwiw, my 801 doesn't whistle either - or at least I do not hear it over
the rest of the noise. Keep us posted if you search it out.
On another topic, I recently installed the longer 801 tail on my plane
- which has the Franklin six engine and flies out of a 5,200-foot
elevation airport. Only four test landings so far but a big
improvement! First impressions are; much more stable in approach,
touchdown speed reduced by 5-10 mph (I need more experimentation under
different conditions) and I actually have some control over when the
nose wheel arrives after the mains. I am pleased to have made the
investment.

Haven't followed this problem, but can offer this: It may be difficult to find.
Several years ago we, our firm, spent MANY hours trying to locate a "high-pitched
whistle" on a police car.
Turns out it was the hollow in the Allen screw which secured the antenna rod into
its loading coil.
Get up about 45 MPH and it screamed.....our tech on the problem was tone deaf.
Cop wasn't.
Put some caulk in the hole.
Kind of like a child blowing across top of a pop bottle.

Hi
I was wondering if anyone else's 801 whistled. I have friends tell me that they
heard me out flying. They did not see me, they heard me. I can hear a slight
whistle in the plane but people outside the plane say it is very distinctive.
My ANR headsets cancel it out.
Now that the weather is better, I'm thinking of hooking yarn tuffs on to the top
of the fuselage and wings. Then taping a video camera to the vertical fin or
rudder and see if I can see any turbulence. I have hopes that adding VG may
eliminate the whistling. I suspect it is right at the rear of or just behind
the top glass.
It is the same area that I suspect still oil cans at low speeds. I thought it
was further back but it started on the ground the other day and I could see the
top oil canning. I put weather stripping Xs on most of the big flat areas behind
the rear seat. This reduced the oil canning significantly.

I recently took a friend up for a ride in my 801 and he loved it. His
one fault was the high pitch whistling at cruise speed which, of course,
ANR headsets don't really cancel out. I have always just assumed that
was the price of having slats on the wings, but I thought I would pose
the question anyway:
Do all 701's and 801's whistle?
If so, is it the slats or the Junker flaperons or some combination?
Thanks,

About 200 hrs. ago I switched to a vernier throttle on the left side and
removed the firewall friction blocks because the firewall flexed at any
setting that wouldn't creep. The flex changed the rpm about 200 rpm after I
set it. The Rotax springs are too stiff, the short coil put too much load on
the vernier and I found myself taxiing at full throttle on a crowded ramp. I
picked a full length coil spring with enough pull at full throttle to be
safe. This reduced the pull at idle much lower and more controllable. The
primary purpose of the spring is to pull the throttle wide open if there is
a linkage failure. All you need is enough pull at full throttle.

I use the standard ZAC T throttles. Took me 9 or 10 tries to get it right.
I'm retired and have more time than money. I'm happy with them (smooth).

No probems here with throttle creep using the stock ZAC setup. It took a
couple of re-adjustments to the friction block as things wore in, but now
the throttle stays put.
It does feel a little "stickey" on initial startup so I excercise it once or
twice before starting the engine.

Greetings Gents,
This worked for me. I kinda like the tee handle but
thought the pinch friction block would be less than
adequate. I used a compression union for 3/8 aluminum
air conditioning line (the union is steel) tossed the
ferules, welded a washer on one end of the body close
to the hex part stuck it through the hole in the dash
put another washer on the back then the nut.
On the throttle rod ( I used 1/4 stainless) goes the
other nut, a 5/16 brass ferule then a 1/4 in collet
from a roto zip. This then went through the stuff on
the dash and tightened down. The tightness of the nut
against the collet gives variable friction.
Works great, fingertip control from locked solid to
easy rod movement <1/4 turn, the only trouble I had
was that the rod came out of the dash panel at an
angle other than 90 deg and I had to machine a wedge
type washer from aluminum bar stock to compensate for
that angle. Grand total? less the 25 bucks, 1 day
thinking, 4 hours doing.
Sears sells the collets, Everco makes the unions.

I have the newer version of the kit which calls for side mounted fuel
sending units in the tanks. After installing the sending units, I decided
to test the ohm reading again before riveting the top skin in place....
The sending unit was indicating 1/2 full (or empty as the case may be). I
filled the tank with fuel and the reading indicated about 3/4 full. I
drained the tank and the resistance showed about 1/2 full again.... We
pulled the tank back out and turned it over a couple of times and the
reading was still off.
We removed the sending unit and found that the float was rubbing against the
front wall of the fuel tank. After checking for proper alignment of the
float, we finally had to put a 1/4 inch offset in the float arm in order to
clear the front wall.
Just thought I would mention this in case someone else is installing the new
revised VDO sending units.
Thanks,

Received my GS-Air position and strobe light system, very impressive

GS-Air was very patient and thorough answering all my excessive
pre-purchase questions, and I received the system two business days
after ordering it. Jabiru is now installing the system in all their

Thanks to all that responded both on list and personally. After looking at
it a bit more it I'm going ahead and assembling the fuselage and then will
fit the gear. I appreciate and will use the advice and ideas that people
gave me. Thanks!
A word of caution/advice/experience.... I built my fuselage on my 12' bench
at the regular height. Looking back now I really should have taken the time
to build a jig on the floor at a more reasonable height that also allowed me
access to the bottom of the fuselage. I knew my bench was flat and level so
I stayed with that though I've paid a bit of a price working on a step stool
and leaning over the fuselage sides a lot. At least I know what to do with
the next one!! People with those aerobic steps have nothing on me! ;-)
