I went to my local Discount tire and they gave me their discarded wheel
weights. They had
them packed in 40 lb boxes. I took and old discarded aircraft innertube, cut
a hole in it and filled the tube with the weight. I then wrapped the whole
innertube in a bunch of duct tape and shaped it the way I needed it for my
flight testing. In my case I put 22.5 lb per innertube.
good luck.

Hey Richard,
I built mine just according to the plans, on a flat table with the tail section
supported at the specified height at the specified distance from the spar. My
wings measure exactly the 3 degrees called for using an angle measure while
it's on it's gear. I would say just trust the plans.

--> Zenith-List message posted by: "Richard Wyness" <richard@wynessr.freeserve.co.uk>
I'm connecting the rear fuselage to the centre wing section, and on drawing 6F5
it says the wing incidence should be 3 degrees. If i align the rear longerons
so that they are parallel to the upper front longerons then this is only 2 degrees.
Is this OK ? Has anyone else had a similar problem?
Richard.

As I pointed out you can always over come the slow cranking speed by
switching power on and off to the second ignition coil (also a GM chip set
up)..Usually one or 2 tries and it fires right up.
Should not be an issue for restart in flight due to the forward airspeed and
warm engine...Not that I ever want to find out!

Subject: Re: Zenith-List: Engine AND ignition working

I sticked to P. Messinger's design. I guess that last
summer, I had the difficulties because of using long
booster cables that I connected a contactor in the
rear fuselage (loss of voltage). Righ now, with the
two batteries installed, the ignition works very much
find.
I found in my verifications that the dizzy needs 135
rpm to produce consistent sparks (that's equivalent to
270 engine rpm). At 200 engine rpm, it will emit
inconsistent sparks. My engine starts at more than
320 rpm.
How did i find that information about dizzy speed
requirement? I attached the dizzy to a
battery-powered hand drill with duct tape. I
connected everything on my workbench and I used my
strobe light that also shows RPM to figure out the
dizzy rpm. I forgot to say that I connected a single
wire and spark plug to the coil.
For testing the engine starting speed. I connected
the single wire/spark plug to the coil and use the
strobe light in the same fashion (while trying to
start the engine.)

Hi, List,
I have a question for the XL builders out there. Mike's
probably building on his and can't answer. That's OK. What have you done
with the rubber spacers that sandwich the main gear at the brackets? Did you
cut the top one so that it just fit between the attach bolts welded on the
bracket? If that's the case, I feel that ZAC would have supplied two long
and two short pieces. I'm ready to hang the main gear tonight or tomorrow
and I could sure use some good advice here!!
Thanks, and God Bless!!

Hello from Rhode Island im building an xl and i thought the rubber mounts supplied
were unprofessional in appearance so i scouted around for some equal rubber
duro hardness material and shaped my own with a grinder what i installed were
barry mounts they use for silencing heavy machinery like a lathe or press the
grinding process is dirty and smelly but i believe woreth it.

--> Zenith-List message posted by: Bob McCoy <bobmac515@yahoo.com>
Hello to everyone, my first post here. I have narrowed
my future project down to 2 airplanes. The Zodiac 601
XL and Vans RV-9A. The basic airframe cost of these 2
kits are nearly identical. I am very interested in
using the Corvair engine in the Zodiac. For me there
is no benefit in using the Rotax or Jabiru as the
final cost would be close to that of a lycoming
powered -9A. In doing my research, I found that
insurance will be next to impossible to acquire using
the Corvair engine. In fact the Falcon Rep. (EAA
approved) told me, "Don't do it, we will not insure
you"! I then asked about the premium for the lycoming
powered -9A and he said no problem, I would be insured
from the first flight. I'm sure this has been
discussed here before, but does anyone have any
experience in trying to get insurance for the Corvair
or other auto conversion? I would like to talk to any
carrier that would interested in insuring the Corvair
powered Zokiac and get at least a ballpark quote.
Thanks,
Bob

I just bought a policy yesterday through Falcon with AIG underwriting the
policy. $250k liability, 35k aircraft value. $1300/yr. They know I'm
installing a Corvair. Rather expensive for no more coverage than it is.

--> Zenith-List message posted by: "HINDE,FRANK (HP-Corvallis,ex1)" <frank.hinde@hp.com>
Also posted to the Stratus list.
Hi guys,
I just replaced my prop shaft bearings and belt. Took it flying and it has
picked up significant vibration. I note from the manual that a too loose
belt will cause vibration. I also know that 1/8th" deflection at 20lbs is
very tight. I probably got more deflection than that because it feels better
and did note signs of the rear bearing getting hot when I dismantled the
drive and up till then I had been running tighter.
I have never had the prop balanced and was thinking this might help, but of
course if it is coming from the belt it might be a waste.
Any thoughts?
The vibration is bad enough to make my toes tingle on the rudder pedals, not
pleasant and it worries me that it might mask another problem showing up.
Thanks

Hi Dirk,
I don't know if you have heard of a company by the name of SUB4. They
are based here in New Zealand and do very good Subaru engine aero
conversions and redrives. They also have one or more agents in the US, I
believe. They have a fuel injection setup for the Subaru which
apparently works well. I spoke to them a year or so ago and asked if it
would be possible to do a system for the Rotax. They said that the
throttle body units would bolt straight on without modification. They
would then have to run a series of tests to "map" the electronics to
suit the engine. They didn't seem to think it would be a big deal and
were confident it could be done without much difficulty. You could
contact them at http://www.sub4.co.nz/team-txt.htm if you want to know
more.

| Subject: | Subaru engine comparison |
--> Zenith-List message posted by: "Bill Steer" <bsteer@gwi.net>
One of the recent posts mentioned being nervous about the belt drive on the Stratus
engine. I share that nervousness, plus some others, with the Stratus engine.
But I've decided to go with a Subaru of some sort, and am interested in
the 100 HP engine from Ram Performance. Zenith tells me the Ram engine won't
fit the Zenith FWF engine mount, but Ron tells me he has the necessary brackets
and that his engine will fit. Besides the fix for the valve guides that's usually
mentioned, Ron's engine uses a gear-driven reduction unit instead of belt
drive, so it looks like an attractive alternative, in spite of being a few
bucks more.
Has anybody else on the list made this comparison? Is it possible to substitute
Ron's engine for the Stratus? What about dimensions such as the distance from
the crank to the prop hub? Does the prop turn the opposite direction on Ron's
engine? I already have the Zenith FWF kit (but the prop hasn't arrived yet),
so want all this to be as compatible as possible.
Thanks for any help and advice.
Bill

I just finished installing new brake pads on my 601HD after something
like 670 landings. Absolutely no wear, but replaced due to having been
glazed - something I could not have observed had I not removed the
pads. It dawned on me that I had never properly broken in the original
pads, and got to thinking that this was probably a common occurrence
among builders for the reason that we usually do quite a bit of
low-speed taxiing around prior to the first flight, and even those who
do "high-speed" taxiing probably don't scorch the brakes several times
right out of the box. Anyhow, per standard Matco / common disc brake
instructions, this time that's exactly what I did and the results were
amazing. I also have brand new tires on the mains (balanced at a
motorcycle shop this time to avoid a flat spot which has been my only
reason for replacing the tires - not overall tread wear), and my stops
from 30 mph + indicated "air speed" resulted in multiple chirps heard
by a friend about 100 yards away. I had a bit of nose down elevator to
avoid inadvertent lift off and loss of tire contact in ground effect,
making the effect pretty remarkable to me. I now have no trouble
holding about 4,200 rpm on run up with no creep at all (vs about 3,200
before). Maybe the bad rap on Matco brakes isn't entirely deserved!
I've sure changed my opinion. BTW I do have the "enhancer" pistons
installed, and saw a slight improvement after making the change quite
some time ago - but nothing compared to the change with the properly
broken in pads.

--> Zenith-List message posted by: "Larry Martin" <earthloc@att.net>
What kind of prop? If it's ground adjustable, you might have the pitch out on
one of the blades, a degree or two would do the trick. Check you prop for nicks
too. If your rear bearing is getting hot, like hot, not warm, it could be
several things. I don't know what kind of drive you have but if it has a track
adjustment, you might look at it. Or the bearings on the shaft could be too
tight, or need packing. Usually the belt would have to be piano string tight
to make the bearing run hot. A loose belt causes a shake at low speeds, generally
not at high speed or under a lot of thrust unless it's about to fall off.
But, I SURE wouldn't fly it until I figured it out and FIXED it. You don't want
to lose a prop. If you do, you probably won't be around to do it twice.

Also posted to the Stratus list.
Hi guys,
I just replaced my prop shaft bearings and belt. Took it flying and it has
picked up significant vibration. I note from the manual that a too loose
belt will cause vibration. I also know that 1/8th" deflection at 20lbs is
very tight. I probably got more deflection than that because it feels better
and did note signs of the rear bearing getting hot when I dismantled the
drive and up till then I had been running tighter.
I have never had the prop balanced and was thinking this might help, but of
course if it is coming from the belt it might be a waste.
Any thoughts?
The vibration is bad enough to make my toes tingle on the rudder pedals, not
pleasant and it worries me that it might mask another problem showing up.
Thanks
Frank 320 hours

I saw a picture somewhere of the inside of the sub4 gearbox
they were using and it has 2 gears which means the prop
turns backward. This makes the zenair engine mount
wrong for this. The mount needs to be offset the other
way. Also the offset of the prop is less with that gear
box so the prop will be lower compared to the stratus.

| Subject: | Matco Brake in Procedure |
--> Zenith-List message posted by: Jim and Lucy <jpollard@mnsi.net>
This is what Matco sent me when I asked them about this
METALLIC BRAKE LINING CONDITIONING PROCEDURE
The brake lining material used in this brake assembly is an iron based
metallic composition. This material must be properly condition glazeding
order to provide optimum service life. Dynamometer tests have shown that
at low braking energies, unglazed linings experience greater wear and the
brake discs can become severely scored. Condition may be accomplished as
follows:
Perform two (2) consecutive full stop braking applications from 30 to 35
knots. Do not allow the brake disks to cool substantially between stops.
On aircraft with tail wheels, exercise caution during stopping to
preventtail lifting. Due the to the efficiency of these brakes, extremely
hard braking could result in lifting the tail from the ground.
This condition procedure will wear off high spots and generate sufficient
heat to glaze the linings. Once the linings are glazed, the braking system
will provide many hours of maintenance free service. Visual inspection of
the brake disk will indicate lining condition. A smooth surface, without
grooves, indicates the linings are properly glazed. If the disk is rough
(grooved), the linings must be reglazed. The condition procedure should be
performed whenever the rough disc condition is evident. Light use, such as
in taxiing, will cause the glaze to be worn rapidly. Use caution in
performing this procedure, as higher speeds with successive stops could
cause the brakes to overheat resulting in warped discks and/or pressure
plates.
Conditioning Procedure for Non Asbestos Organic Brake Lining
The brake lining material used in this brake assembly is a non asbestos
organic composition. This material must be properly conditioned in order
to provide maximum performance and service life. Conditioning may be
accomplished as follows:
Taxi aircraft for 1500 feet with engine at 1700 rpm applying brake pedal
force as needed to develop a 510 mph taxi speed.
Allow brakes to cool for 1015 minutes.
Apply brakes and check to see if a high throttle static run up may be held
with normal pedal force. If so, conditioning is completed.
If static run up cannot be held, repeat steps 1 through 3 as needed to
successfully hold.
This conditioning procedure will generate sufficient heat to create a thin
layer of glazed material at the lining friction surface. Normal brake
usage should generate enough heat to maintain the glaze through the life of
the lining. Light brake usage can cause the glaze to wear off, resulting
in reduced brake performance. In such cases, the lining may be conditioned
again following the instructions set forth in this

Sudhir,
For you building from plans does seem the right thing to do. If you are
ok working with tools.
If you can find a supply of the correct materials in Shanghai or shipped
to Shanghai , some how,
without paying the 50% duty (if no duty, you may want to buy kit parts).
There are many
references to the correct aluminum, steel, rivets and other parts in
the "Zenith-List " Archives.
http://www.matronics.com/archives
You may also need access to some bigger cutting and bending machines for
a few parts.
If you study some of the other plans builders Web sites you will see
many good ideas on
how to build and in some cases in a SMALL space. There are many
builders on the
Zenith-List, look for links to their Web pages.
Here are a very small sampling..............

-------------------
"legalisation and certification : i dont know how to do"
This may turn out to be far more of a challenge than the 50% duty .
Working with any government agency in any country can be difficult.
See if you can find the right people, to ask the right Questions (carefully).
I here things are changing in China, I hope some of those changes
help your Dream!
The Best of luck,
Robin Gould
