--> Zenith-List message posted by: "Phil & Michele Miller" <millerpg@ps.gen.nz>
Hi, Dave,
912 & 912S engines run at 26 deg BTDC. At less than 1000rpm they fire at
4 deg BTDC. The switching is carried out by the electronic modules. We
were absolutely convinced the problem had to be caused by incorrect
timing but have checked the pulse at all 8 spark plugs at cranking speed
and they all fire at 4 degrees. These engines idle well above 1000rpm so
timing at idle should be 26 degrees.
There is no way to adjust the timing but a very clever friend made up
two offset brackets to retard one pair of the trigger coils. We fitted
them then tried starting on one mag and it fired up almost immediately;
when we shut down and tried again it was back to the old kicking and
bucking and wouldn't start. Not really sure what it proved but it
prompted us to check the timing on all 8 plugs as described above.
Fuel pressure on cranking and zero flow is 4.9psi on the standard Rotax
mechanical pump.
Prop is a 3-blade Warp Drive which I believe is the one recommended by
ZAC.
Cheers,
Phil M

Just one more time, Phil,
After all the checks you have done, the kickback and violent rocking you
describe surely can only be that the ignition is firing too soon before
TDC. I've never enquired of Rotax whether their ignition modules include
a retard function at low or starting rpm. If they do, that could be
failing. If not, I would try retarding the ignition up to five degrees.
I don't recall you mentioning a timing check under idling condition. The
flooding would almost certainly be the shaking disturbing the needle
valves. Which raises one more question.. what fuel pressure are you
seeing when you do these cold start attempts? No more than 4
lbs/sq.in.? I prime with the electric pump, then turn it off. We've
had builders here install incorrect higher pressure pumps, which has
caused all sorts of problems. Are you using an unusually heavy prop, or
a very flexible one which is causing the crankshaft to "pulse"? Bit of a
pig getting to the stage you are and putting the money down. Dave Austin

I have always thought I would like to do away with the "Y" stick
on the 601 and since I ordered my RAC grip have been thinking
of starting on this. Any pointers, ideas or guidence? Length or
angle. I was looking at it yesterday and thought I needed to
keep the same angle rearward as the "Y"stick.

Roger,
Thanks for the reply!
I've only got 2 of the instruments and the smallest cluster mount is 4.
It also just seems weird that there isn't any flange on these guys. If
they had a 2 cluster mount, I'd probably pick it up and deal with the
flange issue, but since I have to custom make one, I was curios as to
what others have done.
Thanks!
Don

I'm just at the phase where I can sit in my plane and make noises
(hopefully no one has a video camera near by) and do make-believe radio

Any way, the Y stick actually seems to fit just about perfect. I didn't
like it at first and thought it was going to get in the way, but when
seated, it seems literally just about as perfect as you can get. Did you
want to get rid of the co-pilot part of the Y or just got with a basic

I contemplated the same thing because it felt foreign to me, but I didn't want
to do any more than necessary before getting airborne back in '99, so I left it.
When I began taxi testing, the difference disappeared immediately. Now I am
very glad I left it. I really enjoy allowing a passenger to be lightly on the
stick with me, to get the feel for the motion (or lack of it). The y makes that
natural. It also fits the arm and wrist well while using the armrest. Don

I wouldn't recommend doing away with the "Y" stick. I thought it looked
strange too at first, but now that I'm flying with it I really like it. It
places your arm and wrist at a very comfortable position. Remember too that
the 601 is very light on the controls; you plant your elbow on the armrest
and really only need to use your fingertips on the stick.

I had concerns before building my 601 because of some nasty accidents
several years ago, so I opted for a leading edge tank in each wing, each
with it's own Facet fuel pump, and no header tank. I'm glad I did, and
would do it again if I built another 601.

Depends on who you ask.
The header will let you fly when your fuel pump stops. GOOD
It will also be a fire issue in case of a crash. BAD
I have the 8 gal header with wing tanks and like that.

--> Zenith-List message posted by: "Garrou, Douglas" <dgarrou@hunton.com>
I agree it is a bold statement, but it was boldly borne of my (perhaps
unique) aversion to engine-out landings. Although I would be the first to
admit I am no hotshot stick and rudder man, my flying skills are a separate
question. I think I probably *could* get it down on the salt flats on a
clear day with a BRS and a gun to my head, my point is that don't want to
find out the answer to that question if I can avoid it! :)
The certified manufacturers definitely have had some serious quality control
problems. And when that happens, the ramifications are also likely to be
MUCH more severe than problems with an aftermarket auto conversion, simply
because there are LOTS more certified engines out there (especially, on a
percentage basis, in larger piston-engined passenger planes, all of which
probably use certified engines).
But if the Lycoming crankshaft problem has cost people their lives, the flip
side is that the regulatory regime then *prevented* further injuries,
crashes, or deaths by grounding the fleet. Would a similar review of, say,
recent auto conversion failures result in a grounding of THAT engine,
preventing a FUTURE accident? We'll never know. Would one of these recent
601 crashes -- where injury was averted by skill AND likely by a bit of luck
-- have been prevented if the regulators and their ADs had been on the scene
from the get-go? We'll never know.
Our information about aftermarket auto conversions is completely anecdotal
unless and until their manufacturers choose to put equivalent quality
control and tracking programs in place. And what I was saying in my
admittedly hyperbolic way is that the anecdotal evidence I have seen here is
worrisome to me.
I absolutely appreciate that other people see it differently, and that they
approach the issue from valid and different perspectives on risk, cost, etc.
Put another way, I do not think other people are crazy for flying behind
auto engines -- I only think it would be crazy for ME to do so, since I am
an admitted flying chicken.

That is quite a bold statement to make. If you could not land safely within

Thanks Mark. I was planning on installing a Facet fuel pump in series or
parallel as a backup. How is your system set up? Do you feed your header
tank by pumping fuel ito it from the wing tanks? Or do all tanks feed the
gascolator through a fuel selector switch?

--> Zenith-List message posted by: CLOJAN@aol.com
After building the seat structure on my XL I find that there is quite a bit
of room behind the passenger seat under the luggage shelf. ( The pilot side has
the flap motor.) I was wondering if anyone thought about building a "trunk"
in this area to keep the small stuff concealed that you don't want in public
view? It looks like the back cushion would fold forward for access to this
compartment. Thanks

I have a shut off on the line from each tank as it comes in from the
wing tank (these will both stay open in normal use). They T into a
single Facet fuel pump which pumps to the header. From the header I
have a overflow / return line which returns to my right wing tank.
Also from the header it is gravity feed to the gascolator and then
the Aero-Carb carburetor by Sonex. This carburetor uses very low fuel
pressure, but I would assume that the standard carb on my O-200 would
also work gravity feed on this system.
This is not yet a tested system. I hope to have the air duct work in
my cowl done in the next two weeks and will then be ready to fire it
up for the first time, and give it a test.

I was going to put the G205 RAC grip on it with the elevator and
aileron trim on the stick. I can do it with the Y as I have seen
it done, but I though I would like the single stick.

Thanks for the info, Mark. Sounds like your system works fairly well.
Incidently, do you know why ZAC requires cork between the metal header tank
and the fuselage? I thought all metal parts had to be grounded, including
the fuel tank. When refueling, do you connect the grounding line from the
FBO fuel pump to the headr tank, or to the aircraft itself?
Thanks....Dave

I've thought about that too. I'm thinking that maybe it'll be useful
space to store part of a collapsible bike or scooter that I can sue when
I land somewhere. I plan to wait until I can do a weight and balance on
the completed plane to see if that is even a possibility.

Cork is also used on the wing tanks on the XL. The tanks include a tab to
connect a grounding wire.

well group, I have used 3-m trimite wet or dry sand paper when removing
scratches from my wing spars and such, only to learn today that it is made of
silicon carbide. AC43.13-1b has a chart that says not to use it on alum alloys!
Can anyone tell me why, or if it is any real concearn?
Thanks

Zenith published a whole page in one of there back issues of the news letter
on "acceptable" and "unacceptable" abrasive materials to use on aluminum
construction. According to their list, "silicon" is "acceptable", while the
abrasives with ferrous oxide (iron particles) are not. It was explained to
me that if we sand or scrub aluminum with iron particle based abrasives or
wire brushes, etc, that it is likely that we will embed iron oxide into the
surface of the aluminum which sets up a galvanic ion exchange (corrosion).
Don't get excited, we're talking about "micro corrosion" here. There are
surely many many aluminum aircraft flying around that were unknowingly
sanded with iron oxide abrasives, and we don't here about the paint popping
off all over them, which would be the case if the oxide were a significant
problem. I'd suggest you stick with the "acceptable materials list" from
here on out. I think you can find that chart in the archives under the
discussion of corrosion.
I took my youngest grandson up last week (he's 8 years old) an he had a very
interesting observation looking down at all the houses and cars in
miniature. "Looks like a train set down there Grandpa"....

Thanks for the reply about abrasives. But is the "carbide" an "iron oxide"?
I'm guessing its some form of carbon. I cant figure out how to work those
archives but I'll check the old newsletters for that chart.
Thanks again

Ray,
Question is.......if you're going to ground the tank with a wire, why does
the tank have to be separated from the fuselage with cork? Wouldn't the tank
touching the fuselage be a good ground?
Thanks...Dave

I wouldn't think that relying on mechanical contact would be a reliable form
of grounding. Acceleration forces encountered during flight might lead to
making and breaking the ground connection. The cork provides some padding
that allows a tighter fit to prevent the tank from moving around (it is
essentially a press fit and is not bolted in). It also prevents any
movement of the tank from wearing on the components that it comes in contact
with. The wire bonding will never break the ground path.

I installed the Mitchell fuel pressure gauge - maybe it's similar. It also
had no flange, but as I recall there's a back-plate and a securing screw.
I used L-angles to make a little 'tray'/mounting well that the gauge slides
into and is secured at the back with the screw -- at least that's what I
recall. Don't have my aircraft nearby to check or take photo.

Yes, right up to the moment that the vibration induced friction wears a hole
through the tank!. The cork is an anti chafing mechanism.

I chopped the pax side of the 'Y' off before first flight - not planning any
dual training and the Y interferes with my access across the panel/lower
sidewall on the right.
I still don't care for the pilot side of the Y as it tends to get in the way
of my inboard knew - but I am long-legged. I am seriously contemplating one
more 'chop' to remove the Y altogether and install a wooden grip with 1
pitch-trim 'cap' switch.
I don't care for the MAC grip with the small trim buttons - they are not
intuitive; not easy to find with the finger tips without accidently
trimming; and one of the aileron buttons tends to come to rest against my
kneecap when I'm not noticing it ... i.e. Hey? why is the aircraft
banking???? ;-)

++ Not sure. I did a very quick search in the archives and found several
comments referring to the list that Zenith posted, but didn't find the
entire list. Emery cloth, wire brushes made of steel, and ferrous oxide
abrasives were mentioned as being "prohibited". I did find a reference to
the issue that it was printed in, that being issue # 84, October of 1994.
That date sounds too old as I began my aircraft in 1997 and the list showed
up in one of my newsletter issues after that.
Maybe one of the guys out there is good at looking things up..........

Jack,
I'm building a 601hds and found adding a stowage area behind each seat a
very
worth while effort. I framed the periphery of each side between the rear
spar, sides and center and added a
hinged rear bottom that allows access for cable adjustments etc. and
clearances for batteries that are just behind the rear spar on the right
side.
Images can be found on the website. www.macsmachine.com Large
assembly/fuselage to wing.

Indeed, I'm in the same situation, although I am more interested in 701's

Is there any reason you can't just cut off the "Y" completely, and have a
sidestick, which is used on the Airbus? Seems as if control would be better
with the pilot's arm on the armrest holding the stick. Just a thought.

ZODIAC Enthusiasts:
<SNIP> Next month we'll have the ZODIAC XL at the NW EAA Arlington fly-in
(July 9-13, Arlington, Washington). Demo flights will be available (by
appointment) at the fly-in. Detail: http://www.zenithair.com/events.htm

Grant,
Thanks! If you ever get the chance to take a photo, it would be much
appreciated.
I went ahead and left a message for Mitchell and hopefully they'll have
a smaller mount for me. The guage didn't have one, and AC&S mentioned
only 4 and up clusters.
Can't wait to finish. Seems soooo close now.

I installed the Mitchell fuel pressure gauge - maybe it's similar. It
also had no flange, but as I recall there's a back-plate and a securing
screw.
I used L-angles to make a little 'tray'/mounting well that the gauge
slides into and is secured at the back with the screw -- at least that's
what I recall. Don't have my aircraft nearby to check or take photo.

--> Zenith-List message posted by: "Don Honabach" <don@pcperfect.com>
Can any one recommend a good way of cutting a 4130 Steel Plate (1/8"
thick)? I tried an abrasive saw, but didn't like the results or the heat
generated. I've also talked to some local sheet metal shops and they
mentioned that a normal sheer probably wouldn't handle the 4130 very
well. Do I just need to find a cut-off type metal band saw or ?
Thanks!

Hi Don:
I do this routinely on a small bandsaw -- a 14-inch Delta 3-wheel benchtop.
The key lies in the blade and the blade speed. I use a 14-tpi bimetallic
blade. Standard blades won't cut it -- they'll just get dull in a hurry.
Keep the blade speed fairly slow.

My two cents worth...I chopped the "y" and used the MAC handle and have had

Dave,
I have the 601/Rotax 912 w/ 16 gallon header tank. Safer in terms of fuel
flow. Worse in terms of crashworthiness. Simpler in terms of fuel system. Less
room behind panel for instruments...in fact it is not practical or maybe even
possible for vacuum instruments. I had a forced landing a while back, and one
thing on my mind was all that fuel in my lap. Then again, there was a little
gravity flow with the header tank, perhaps that is what kept her sputtering
along just enough for me to keep airspeed up for those few critical seconds.
In other words, it is simply your call, there are plenty of arguments both
pro and con. I guess simplicity is a big one, though.
Happy building and good luck.

Thanks! I've been in communication with the factory and am trying to
schedule a demo ride. I flew down to Copperstate last year for the same
purpose, just prior to purchasing the XL kit, but air traffic conditions
didn't allow for a demo flight in the short time I was there. Still
building "Flight Unseen" and am really looking forward to a factory demo...

One last try, Phil. You seem to have done good diagnostic work.
Is the key on the crankshaft loose, letting the timing wander on cranking?
Is it possible you have a leak from one plug wire (cylinder) to another,
causing the kickback?
Can't think of anything else!

Gasoline is flamable... taking this in account,where ever you install
the tank(s) there is always danger of fire, any gasoline in the grass
with a short circuit can ignite.
Is one in a million to be so lucky to crush in the middle of 2 trees
exactly the gap of your fuselage, so the gas tanks stay back with the
wings.
The best thing is to aboid bad weather, in case of engine failure, fly
the airplane all the way down, if it falied, will not start, you just
will loose valuave time (and altitude), in the mean time close the
gasoline valve, shut the master switch, and do the best your training
and practice will show your insticts.
Saludos
Gary Gower.
PS. When ever you dont have a special place to go, instead of just
flying around, practice emergency landings with and wthout engine.
This is safer than remote gasoline tanks.

Is the heat generated by the cutting wheel really an
issue? I'm asking because when I asked my weldor
about heating the metal during welding or forming, he
told me that there is no problem if you allow it to
cool down by itself (he calls this "normalizing".
Normalized 4130 is called 4130N. He said that if you
sink the metal in the water to cool it rapidly, then
it becomes "tempered".
So I think the concern is not the same as with 6061-T6
which would loose its T6 property if heated.
Michel

I've seen this not yet on XLs, but on HD and HDSs.
See this one:
http://mthobby.pcperfect.com/ch601/images/Dcp00267.jpg
The builder made a long compartment that allows him to
bring pairs of skis. Oh... it may take a while to
figure the picture out... it's tilted on the right
side (top is on the right). On left (bottom), this is
the reclined seat cover.
Another person I know made small compartments behind
each of the two seats. It's usefull for storing
headsets, lunch or other things you don't want to
leave on the shelve. See:
http://mthobby.pcperfect.com/ch601/images/pprjgk4.jpg
For my part, I elected not to do this. The "behind
the seat" section is my rear electrical bay where the
master solenoids, battery bus fuse blocs, autopilot
servo, ELT and Strobe power supply are positioned.
See:
http://mthobby.pcperfect.com/ch601/images/Dcp01505.jpg
http://mthobby.pcperfect.com/ch601/images/Dcp01218.jpg
http://mthobby.pcperfect.com/ch601/images/Dcp01144.jpg
I will also install my transponder antenna in that
area.
Finally, all turnbuckles for adjusting the tension of
elevator, rudder and ailerons cables are in that area:

My tank didn't rupture that I'm aware in my crash last week. The gas all
leaked out over the course of several hours after the accident. I think it
was because the gascolator was sheared off and/or fuel lines breached by the
crash. This would have been true for wing tanks as well.

Thanks, Patrick. Maybe the best bet is to install another fuel shutoff valve
connected to a drain line through the floor, so the fuel can be dumped in
flight after an engine failure.

Simply my opinion....If you really need me to clarify.
I have visions of a 16 or 8 gallon fuel tank rupturing on impact. Then being
ignited by an electrical wire tearing loose behind the panel. All this while
the fuel is pouring onto ones lap (Isn't this how napalm works). While one
is trying to unfasten ones seat belt and trying to get the canopy open, ones
cloths and skin are melting. If one does make it out alive, one may wish they
didn't.
Again this is only one pilots opinion...

I keep a news paper picture in my garage to remind me
about safety. This is the one of that plane that had
bagage compartment open in flight. The plane stalled
above the ground and did a hard landing (it was not
referred to as a crash, even though the G load may
have exceeded 9 Gs). Header tank ruptured and plane
(cabin) got in flame.
I decided right at that moment that I did not want a
fuel reservoir above my legs.

Ray:
I was able to fly at my rudder building session at the ZAC factory. You
will be pleasantly surprised at how nice the plane flies. It was tight and
handled well. I was a bit surprised at how nice the finished product looked
and flew. You will enjoy the demo ride (when you get the chance).
You are progressing well - thanks for all the pictures on your web site. I
enjoy looking at them from time to time.

Thanks! I've been in communication with the factory and am trying to
schedule a demo ride. I flew down to Copperstate last year for the same
purpose, just prior to purchasing the XL kit, but air traffic conditions
didn't allow for a demo flight in the short time I was there. Still
building "Flight Unseen" and am really looking forward to a factory demo...

Hi Scott,
Thanks for the flight evaluation. I've seen several. Including an
absolutely fantastic piece of workmanship at RIU last time I flew in to
visit my parents. Looking forward to a ride!
Thanks for the website comments too!

Cork is insulation from vibration.
The tanks are grounded to the plane by a cable riveted to a tab in the
side of the tank (701).

insulation from vibration, also to prevent any movement betwen the tank
and the wing, like using a file... will eventualy leak fuel.

Concentrate in flying the plane down. Once in the correct glide path
and the "target" landing space secured, shut the fuel valve, switch off
the master and as a insurance, a little prayer.
Practice to find the position of both (master and gas valve) without
looking, like when (on the road) we change from main tank to reserve in
the motorcycle.

In the book "Gift of Wings" by Richard Back, there is a part where he
mentions something like this: "Take care of what you think or wish,
because some day you will get it" "if you want a plane you will own
one some day" not a quote, just what I remember, great book.
In the event of a "regular impact" crash landing, hard enough to brake
the gas tanks (also legs broken maybe), the posibility of the plane
resting a little in one side are big (front wheel and one side landing
gear colapse).
So we will also have gasoline driping fron the higher wing tank to the
neck (in a high wing plane), or in the kidneys area (in a low wing
plane)... or all over the place in the floor (in both cases).
If we manage to shut the master, and dont land in rocks or pavement
(metal friction), the chances of fire are low... I HOPE.
Saludos
Gary Gower.
Why dont we think a little positive from now on? Lots of pilots never
crash in their lives, only a hand full of the forced landing one's wont
survive. Keep calm and react as trained.
