When you do the Alumiprep make sure you do a water break test. Just
pour
fresh water across the part and it should sheet evenly... If not scrub
again
in places where the water didn't sheet.

Kevin-
That's what I wanted to hear. Don't care where you live- there's a
NAPA
within spitting distance. Of course, if it's not in stock........
Here's my big question. It means a lot to me because depending on
the
answer, I have to shift from "Build" to "Scrub down" mode before going
any
farther.
Once you get some corrosion, do you have to strip interior surfaces
clean like you would for a painted surface BEFORE applying your Zinc
Chromate or other protectant, or can you just apply the protectant? I
don't
know- maybe skins stop corroding when you separate so moisture doesn't
collect between them and you don't have to do anything. I don't think
you
have a choice but to thoroughly clean the painted surfaces.
All input, especially from builders who found themselves in the same
situation, is appreciated.

Dave,
The throttle settings do change as the engine moves from thrust and roll
from torque.
I think if the control rods are parallel in all directions both carbs
will change the same amount.
I'm not sure how much they move but I bet it's just a few thousanths due
to the 14 inch long throttle rod.
I think the vacuum crossover tube should fix any slight variations.
I use ball rod ends to get rid of any side loads on carb.

Hugh,
How do you counter the thrust inputs on the engine? I would think
with this setup engine thrust equates to carbs out of sync. It doesn't
take much of a movement on the linkage arm to pull different vacuum
loads form one carb to the other.

Bill,
In the process of preparing for paint, especially my water-thinned
primer, you have to scrub the plane clean, etch and rinse it. The
problem I find is
that to be able to prime, you must do it within 12 hours of rinse so
that the oxides don't re-establish before primer. Hard to do because
the interior of
wings and things get damp during the rinse and are somewhat resistant to
the air gun blow dry process. Do check that the primer you're going to use
is compatible with the zinc chromate you put inside your plane. I've
been doing a work-around for an external primer that isn't compatible by
extensively
drying the seams and rivets.

--> Zenith-List message posted by: "Johann G. Johannsson" <johann@rafpostur.is>
Hello Tommy.
I used the Vernier throttle from ACS wit the solid wire end, A820 on both sides.
I started with the throttle on the left side, and then decided to install it
on both sides, because it was the perfect setup.
The old T from Zenith is still on the right side in the picture on my home page.
Did not like that long stick because it was hard to control.
If you need the part to attatch the cable to the steel rod, I could send it to
you. Just contact me off list with your address, and I will ship it to you.
Best regards,

The throttle pictured on your website is an A-820 push-pull friction
lock throttle, not a vernier throttle (A-750, A-790 or A-970).
A-820 friction lock throttle control
A vernier throttle does not have the friction lock knob like yours.
It has a ball bearing mechanism inside the barrel that allows small
adjustments to be made by twisting the knob and a button in the
center of the knob that releases the vernier mechanism to allow large
adjustments to be made by pushing or pulling on the knob.
A-790 Vernier throttle control
I don't know any convenient way to use two of these vernier controls
to control the same engine or even any other type of control along
with a vernier. You would have to disable the vernier mechanism on
one to use the other because the vernier mechanism prevents the
control from moving unless you turn the knob or push the button.
That's why I decided to eliminate the second throttle control when I
installed a vernier control.

Subject: | Re: Zenith-List:Changing out the Lexan windshields on CH2000 |
--> Zenith-List message posted by: TYA2 <tya2@4-fly.net>
Any one got any tips on changing out the SH_T lexan windshields and side
panels on a Ch2000? Mine are about to be replaced for the 4 th time in 12
years but the first time by me. What do I do? Drill out the old
rivets? Try and match the rivet pattern on the new one, cleco it in
place, and then pop rivet it in place? DO I start at the side and work
around to the front, or start at the front and work to the side? What
about the stuff that keeps it from leaking. Zenair sold me new windshield
but no new washers? Are they standard pop rivet washers? What about the
stuff that seals the windshields? In talking with my local a an p he
indicated it was fiddly scut work that he didn't want to be bothered with
and that I might as well do it myself. What about corrosion proofing the
rivets head before reassembly?
Looking for ideas. I was disappointed Zenair had not come up with a
better system than flat pieces of lexan that have to be forced into shape.

I've been advised by many that a vernier throttle on a Rotax is not
recommended because of the carb design (full throttle on linkage
break). I have the A-820 and it works perfectly. I'd hate to have to
mash a vernier in an emergency considering you have to push on the
button to get it to move!! Better for mixture control in my opinion...

List,
I have an opportunity to purchase a used Microair 760 radio for a good
price. I current use an ICOM handheld as my primary COM radio attached
to an external antenna. I works well, gives a good signal and is easy
to change frequencies. The down side is the display is small, difficult
to read esp. in sunlight. I thought a panel mount compact unit might be
ideal. Does anyone have experience with the Microair? Would you buy it
again? Any problems other than some compaints I've read of ignition
noise? Anything to look out for.? I must make a desion by tomorrow
afternoon. Thanks

The easy way around that, if it bothers you, is to attach the throttle
rod
to the engine block instead of the fire wall.

Subject: | Re: RE: throttle |
I don't see why the carb design has anything to do with the use of a
vernier, if the linkage breaks the carb will go to full throttle no
matter what type of throttle is used. My Subaru has a carburetor
setup similar to the Rotax. As far as mashing on the vernier in an
emergency, if you need full power, just push on the face of the knob
with your hand or thumb exactly the same as you would with the A-820
and you will push in the button and advance the throttle at the same
time. To retard the throttle, grab the throttle with two fingers and
thumb like normal, squeeze and pull. Both actions are natural and
automatic and don't require any special effort. The advantage of the
A-320 is that you can use two of them for dual control where you
can't with the vernier. To me this is no hardship since I don't plan
on flying solo from the right seat. I think the single throttle setup
is a bit simpler and lighter. Either setup should work fine.

Hi Jerry
I bought a 760 plus integrated intercom back in 1999 when I started the
panel construction and ran it to listen to local traffic on occasion.
Approx. 15 months later it became inoperative (not yet in service, but just
outside warranty). It cost significant dollars to fix. Since then it has
failed again and I resolved to buy a seperate intercom from sigtronics
because the second failure was the Microair intercom. Not impressed !
My first Microair transducer had to be replaced and that is now up to Ver 7.

All this with TSO'd gear.... and my bird has yet to leave the nest.
