Subject: Updated Drawings
Zenith Fans!
I have just been on the Zenith website and downloaded the April 2005 drawing updates.
I'm amazed at the level of change with fuselage skins going from .016" to 025"
and some major changes to the empennage. Why

The L connection on the regulator is for a lamp. The only actual reference
in all the rotax manuals is that it is for a "charge indicator lamp" but no
other explanation.
Is the Light off when battery charging?

On the rudder, you now leave off the tip rib. Instead you have a fiberglass
tip/fairing that stiffens the area up. It has a very pleasing aerodynamic
appearance.

Brian,
With the light hooked up properly, it will light up only when the engine's
generator is no longer putting out voltage (regardless if battery is charged
or not) indicating the generator is defective, fuse blown, etc (or engine
has stopped, but you will get other indications of that!) Very similar to
the old idiot light on an auto's dash.
To test it, with the engine stopped, turning on your master/alternator
switch, it should light up, then go out when engine is started and running.

I concur, this is exactly the behaviour of my setup. I did a lot of
head scratching with the reg/rec wiring along with the capacitor but
got it solved after a phone call to Rotec and looking at the list
archives.
Mine goes out when the engine stops (actually fades as the capacitor
is discharging) and comes on when engine runs .

--> Zenith-List message posted by: <jeffglass@starband.net>
I've just had to replace both main gear tires on my 601 HDS due to center
tread wear.
The new tires I got from Matco are the same size as the old, 4.80X8, but
are now 6 ply. The stated tire pressure ON THE TIRE is 90 psi, tubeless.
I just got off the phone with Matco and they gave me the following info:
4.80X8 2 Ply pressure 35 psi
4.80X8 4 Ply pressure 60 psi
4.80X8 6 Ply pressure 90 psi at gross weight of 725lbs on tire....
However, even Matco thinks this pressure is to high. By my W&B chart I
noted that each main carries about 225 lbs. empty. Any suggestions on
what the correct tire pressure should be? Sebastian says 40 lbs...
Also, I was told the correct torque values for the 3 wheel bolts is 90
inch pounds. Matco specifies two different values on their technical
sheet that comes with the wheel. One is for Aluminum at 80 inch pounds
and the other is for steel at 90 inch pounds. THESE VALUES ARE FOR THE
1/4X20 BOLTS WHICH ARE STEEL GOING INTO STEEL BOLTS!
As always, can't wait to see the replies!

--> Zenith-List message posted by: <max.johansson@nokia.com>
Trevor
A month ago I was bench testing a Rotax 912 regulator/rectifier
using a rotary transformer instead of the engine generator coils.
Therefore it was easy to simulate various rpm and exercise the
lamp. A real battery and a real load was used.
There was some strange behaviour when the L is connected with
a small bulb to ground, but the operation was very exact and
distinct when the bulb was connected to plus 12V at any point
behind the master switch or relay.
They probably have an open collector comparator output to
indicate when the charging voltage is less than the battery
voltage, because the transition was anything but gradual.
Hope the above explains the behaviour of your lamp...

At Oshkosh a couple of years ago I asked one of the major tire companies
about ply ratings and which I should use. He said that the number of plies
should match the gross weight. So if your plane specifies a 4 ply it will
do no good to pay for a 6 ply. I think that the pressure you use is also
related to weight, not the number of plies. You want a fixed number of
square inches on the pavement and that is a function of how much weight it
is supporting.

Victor,
A very good, if not definitive, discussion of all the issues associated with
fuel system installation, care, and feeding, is found in Chapter 8 (page157)
of Tony Bingelis' book "Firewall Forward" (ISBN 0-940000-93-8). Specifically
you will find a section, "Fuel Flow Test" starting on page 175.
Tony's books are on the "MUST HAVE" list. They are just so chock full of

| Subject: | full fuel indicator? |
--> Zenith-List message posted by: ron dewees <rdewees@mindspring.com>
Hi Zenair drivers and builders,
After 70 or so hours on my 601 I am beginning to start working thru my
list of squawks and have gotten to this one. On my 601 HDS I pump fuel
from wing
tanks to my header tank using a low pressure Facet pump. My wing
tanks hold 10 gallons and my header tank holds 8 gallons. I can not
empty my wing tanks into the header without overfilling the header
tank so I need a foolproof way to let me know when the header tank is
full.
The capacative fuel gauge in the header tank just isn't accurate
enough to indicate the last inch or two of fuel level to the top of
the cap. The cap is vented so if I overfill the header tank it spews
gas all over the canopy and makes me VERY anxious till I turn off the
pump and wait a few seconds till the level goes down.
My present solution is to put a float and short wire thru the header cap
and try to watch for the rising bobbing wire and cut off the boost pump. In
theory it works fine, but the pump takes two minutes per gallon to
transfer fuel and my attention span must be less than 2 minutes cause
I often get distracted and get a spurt of fuel out the cap before I
cut the pump off.
Can anyone think of a mechanical or electrical system to either warn
me of impending overflow or cut the pump off before it overflows? I
don't want to use a magnet and reed switch on the rising wire on the
float cause I don't want a potential spark in the middle of a spray of
gas. The wing tank is mounted and doesn't have an extra inlet that would
permit recirculation back from the header tank.
Thanks

Does anyone have any idea as to why on the latest drawing changes that the
main gear was turned around with the tapered part now in the rear , moving
the
main gear 4 inches closer to the nosegear?
Also my kit came with the 5/8 nose axle and wheel. What is the group
opinion
of using that or purchasing new wheel, axle and bearings?

With my personal experience with ultralights (fat UL in USA), the best way I found
to have the correct pressure in the is this:
Park the plane in a hard surface (no grass) add air until the complete tread area
of the tire is touching the floor, only the complete sidewalls are out..
Try the plane, sometimes you will need to add air to get about 1/4" of the side
of the tread off the floor, this will work ok.
Remember that also the tire acts as "spring" for the plane landing gear.
Has worked for 15 years... But if I am wrong I can learn :-)

is 730 and 225 each of the mains is close. I carry 35 psi each tire and
they aren't hard up, but not
hard to roll either. No perceptible wear on my tires but probably due
to so few hours.
I'd hold your pressure to between the 35 and 40 as better to keep the
landings soft. Like your car,
over inflation causes a hard ride and is cause for excessive mechanical
wear on strut bearings, etc.

Why do you have to fill the header tank to the very top?
Anyway take a look at this:

I seem to remember that Chris Heintz suggests the tires should depress by
1/3 with the weight of the a/c empty on them.
This helps if you ever have a hard landing.

George,
It would seem that putting the gear about that way would reduce the
loads on the nose wheel.
The mains are not being stressed as much as the nose gear with the
higher horsepower engines
popular today. I was taken back by the installation of a 115 Lac, but
they're all 100 to 120 hp
and the nose gear hasn't seen any relief in the new design save a
doubler added back onto the fork.

Ron,
I have a tube from the top of the header that goes down and out to
within an inch of the right center wing joint.
Over flow can happen there. Perhaps safer. You might be able to make a
cutoff float switch that can be hung in the top
of the tank. Your overflow situation is what I'd call untenable but my
brain works the same way, so something
should be done. I recollect switches that are intermittent or that you
have to hold down to make contact and that
might just trigger your presence enough to keep the focus. I pump
fuel over frequently, but only move enough to
bring the header gage up a couple of gallons at a time.

Hi Craig,
Thanks for the link. The main reason for filling full is that the
header tank is only 8 gallons, and my reserve is 2 gallons when the
gauge reads empty. 6 gallons operating fuel isn't a whole big safety
margin. If I ignore the top 1 gallon it's 5 gallons and I have a #3
pucker factor from takeoff.
I will take another look at the smart pump. It says it tells me when
the aux is empty, rather than when the header is full. I know when the
aux is empty as the Facet pump will start sounding like a jack hammer
when it's dry.
Thanks
Ron

Thanks Larry,
As Craig pointed out, maybe I am being too paranoid of lower than full
fuel. When I trust the capacitive gauge I should feel better about 3/4
tank reading. I'll look at overflow situation to see if I can jetison
it overboard rather than into the canopy.
Thanks for the ideas.

I do the same thing on mine. My header fuel gauge is a Cruz Pro with
digital readout. You can program it to sound an alarm at a hi value and at
a low value. It makes plenty of noise and can be heard over my engine
without a muffler. Since my header is a 5 gallon tank, I have my hi value
set to 4.6 gallons, and low value set to 1.7. I usually don't like to see
less than 3 gallons in the header, so I add fuel long before alarm goes
off.
Cruz Pro has one that will automatically turn your transfer pump off and on
for you, but I prefer to have control over that. It can also "learn" your
particular tank, for those with odd shaped tanks. www.cruzpro.com

Follow the link to this and you can see their non-contacting,
non-electrical (optical) fuel sensor:
http://www.ppavionics.com/FSD.htm
With the right logic you should be able to shut down your transfer pump
when the header tank is full-ish. I'd use two at the same level and shut
down the pump if *either* says the tank is full.

Hello All,
Well, I'd like to build an airplane sometime soon and would like one
that will go minimum 150 mph can carry 2 adults along with 2 sets of
golf clubs (50" long each) with maybe 2 duffle bags as well. I'd
also like it to burn no more than 6 GPH and be capable of being flown
IFR and can be built relatively quickly (under 1500 hours). I'd also
like it to be under $40K. Oh, it must be metal construction and
suitable for the first time builder. Is such a beast out there?

If I do, please recommend the type of protection and where I can obtain this
