| Subject: | Aileron Horn Clearance? |
Hi guys,
In final assembly of my right wing, I'm noticing that with the aileron mounted,
the aileron control horn just barely clears the bottom flange of the rear channel
when the aileron is in the down position. It's a little too close for comfort
with me, so here are my questions:
1. Roughly how much space should be between the horn and the bottom flange of
the rear channel. Right now, mine is 1-2mm.
2. Am I worrying about nothing because in normal opertion the horn will never
travel that far? There is an aileron stop, so that leads me to believe that the
horn will travel that far in normal operation.
If it turns out to be too close I can just make another horn and mount it at
a slightly different angle to provide more clearance (which is probably what I'll
do anyway for peace-of-mind), I was just curious if anyone else had experienced
this.
Thanks!

There's a propeller manufacturer that does an in-flight adjustable
propeller. I'm not sure if it's electric or what -- it's not the
hydraulic kind requiring oil from the engine.
Maybe more than one manufacturer has such propellers.
Anyone have experience with them? Positive? Negative?

Yes it will, everytime you do a "runup" and check for "full free travel"
of the control surfaces. You know the accronym, CIGAR. C-controls,

| Subject: | XL Wing Root/Tip Shaping |
Here's a quick question for those that have BT/DT.
Its been suggested to make a paper template of the contours of the wing skin root
and end. Easy enough to do; but do the tabular values on 6W9 represent a plan
view of the 3 dimensional wing or the curve, as laid out on a flat wing skin?
If the latter, the template method is easy. If the former, this is kind
of tricky.
How have others accomplished this task?
Thanks,
Doug

| Subject: | Fuel Hose Options |
Folks:
IMHO, it is possible to put together a reliable fuel system using rubber
hose, but I would not do it using the SAE J30R7 type hose and worm type
hose clamps that Zenith provides with the kit.
I am replacing that hose with the modern J30R9 type Teflon-lined fuel
injection hose, which is designed for the higher pressures and higher
temperatures associated with modern automotive fuel systems. I am also
replacing the clamps with screw clamp units sized specifically for that
hose (web search for "fuel injection hose clamps"). These hoses easily
go car lifetimes in the engine compartments there.
As you might expect, this stuff costs quite a bit more (maybe 3X more?)
than the lower-spec parts, but still less (maybe 1/4 as much?) than
aircraft hoses. And it retains the relative ease of length-sizing,
installation and maintenance of rubber hoses. If you fire-sleeve or
otherwise protect the hoses in the engine compartment, IMHO you can get
an equivalently safe system.
As always, you have a choice as the builder. In my case, I have chosen
to go for regular inspection and replacement (possible because of the
lower cost and ease of maintenance) instead of total "invulnerability".

The 640 and the CH2000 spec the same type hose. For the CH2000, they give a 5 year
life limit on the hoses. In my 640 I changed everything from the tanks to
the firewall to aluminum lines. Fairly easy, cheap, and no life limit. I really
didn't want to mess with having to change out the hoses every 5 years. I would
be surprised if vibration from a well secured fuel pump is significant enough
to require flexible hose, but I really don't know.

| Subject: | Fuel Hose Options |
The pressurized side of my fuel system (past the fuel pumps) have all been
done with Earl's Performance Plumbing Auto-Flex stainless steel braid reinf
orced synthetic rubber hose, with AN6 Hardware. More info here: ( http://w
ww.holley.com/division/Earls.asp#17 ). I purchased it all from Summit Raci
ng ( http://summitracing.com/ ). For the last two years, I've been flying
with the gravity side of the fuel system using the rubber hoses supplied by
Zenith. I took the wings off to bring the plane home from the airport for
other upgrades, and decided to upgrade the fuel lines in the wings, so the
entire system will be the same, higher quality stuff. The rubber hose sup
plied by Zenith still looks good, and there were no problems before.Phil Ma

??? The D180 will split screen or go full screen on both the EFIS and engine monitor
modes. It really is a D100 and a D120 in one box. The Screen has a 7" diagonal,
and can easily be reached and read from the 601xl's seats. The D180 will
work with capacitive probes, but a Cap to Voltage converter is needed. We do
sell them, call for pricing. The D180 installation guide is available on our

| Subject: | Right and Left Hand Turnbuckles |
I saw on the CH601XL plans for the adjustable turnbuckles for the elevato
r
to mounted at the elevator horn on the dual stick configuration between t
he
seats. How gross is that? The bottom one would never be accessed without
a
5 year old's size hands in a contortionist position. So I ordered from
Aircraft Spruce the correct threaded turnbuckle eye (P/N AN 170-22RS Cabl
e
Eye) and installed my adjustable elevator turnbuckle just above and sligh
tly
aft of my rear bottom access hole. Not only is it easier to adjust and
safety wire (Single Spiral with .041 wire) but I can check cable tension
right there and make adjustments in the future as necessary.
I am using Push/Pull control rods for the ailerons. Each rod has a right
hand and left hand threaded fitting and jam nut for minute adjustment. T
hat
way, if one of my ailerons is out I can bring it back in with minimal eff
ort
Once locked, it will stay for ever.
Hope this helps someone out.

| Subject: | Jab Dual Throttle Setup issue |
Hi All,
I just got my dual throttle setup installed per the Jabiru USA
instructions and have an issue with the roughness in throttle movement
when the throttles are firewalled. The throttle cable has to bend when
its firewalled as the arms on the bar mounted on the firewall shelf tilt
down in this position and this causes alot of stiffness and roughness
when pushing the throttles that far in. I havent hooked up the middle
cable to the carby yet so this friction is just from the two throttle
cables.
Any suggestions for improving the movement here ? Can I just grease the
cables ?
Thanks,

For those using the 3300A engine, IVOP is NOT recommended. IVOP is a electric,
in-flight adjustable system. My buddy has one on his CH601HDS with a Subaru engine
with a Propeller Gear Reduction Unit. His Subaru is water cooled with the
radiator hanging out into the slip stream below his cowl. Does not rely on the
prop for cooling air.
The IVOP unit, upon closer examination, has no wind generation capability within
12 -14inches from the hub. The propeller base is round and not shaped for air

Here's a quick question for those that have BT/DT.
Its been suggested to make a paper template of the contours of the wing skin root
and end. Easy enough to do; but do the tabular values on 6W9 represent a plan
view of the 3 dimensional wing or the curve, as laid out on a flat wing skin?
If the latter, the template method is easy. If the former, this is kind of
tricky.
How have others accomplished this task?
Thanks,
Doug

Hi Tracy, I seem to remember finding an error in the plans for that sett

way is to add the 8mm and set the outboard flaperons even with the top
contour of the wing... It has been a few years since I did that though.

Just wondered if there is anyone out there with a set of steps that came
with your kit, that you did not use. I am going to order a set here in the next

awhile back, but the rivet holes are really big. I do not weld, so I am at the

John,
I had the same difficulty with the cable end moving around a radius and
resolved most of it by adding a link
that stays straight with the cable but allows the link full travel.
You'll have to study the linkage shown in
the image below. This will leave you with a much smaller amount of sweep
thru the firewall and you'll be less
likely to break the end fitting.

I bought them from someone on the list. I have actually thought about
buying some A6 rivets. I think that they would work. Bolts would work, but would
not look the best. They do not cost that much, so I might go with new.

So, from the above responses, it sounds (if I'm interpreting this correctly) that
the first responder laid out his curve on the skin as installed on the wing.
The second responder laid out his curve on the flattened skin (or the same
thing since the paper method duplicates the results of trimming before installing
the skin).
Sounds like both produced acceptable results although I'm not clear why. These
two interpretations would not yield equivalent curves.
Maybe I should just ask Zenith what was intended.

Doug,
I laid out the curve on paper. I laid the paper on the in-place skin and traced
the curve. Paper WILL bend to the bowed skin and the results are just as though
the skin was flat. There is no difference here.

I would bet that no one at ZAC really knows except whoever originally did
the measurements or calculations for the dimensions on the plans, and that
the difference is probably negligible for practical purposes. I remember
doing mine curved in place and don't recall checking what the difference
would be if doing it flat. In fact, without looking again at the plans, as I
recall, the way the dimensions are given it would not make any difference if
flat or curved.

| Subject: | Re: Corvair Crank tap |
Bill,
The way I did mine was to re-tap all the holes for standard 3/8 fine thread and
then used standard AN hardware. I know this is contrary to William Wynne's recommendation
as he says it's very difficult to get the holes straight when tapping
but the way I solved that problem was to make a jig which is a round piece
of aluminum with the same bolt pattern as the crank end, and a pilot that fit
the crank end. The hole sizes in the jig were in pairs. Two were a snug fit
on the 11/32 bolts. 2 were the size of the tap drill for the 3/8 fine thread.
2 were sized to guide the tap, a little smaller than 3/8. I bolted the jig
on using 2 of the 11/32 bolts. And drilled out 2 holes the tap drill size
for the 3/8 bolts. I unbolted the jig and turned it so that I could then tap the
first 2 to 3/8 fine. After the first 2 holes I opened up the 11/32 holes in
the jig to 3/8 and from there used 3/8 bolts to hold the jig. The jig has to
be accurately drilled. I drilled mine on a milling machine and a rotary table.
It might even work to make the jig with all the holes one size if you can find
bushings to size it down for various sizes required. But that idea was hind
sight.

Yes, Savannah VG does have jury struts, just like the airfoil one in the

Here's a copy of the original post on the Savannah forum on Yahoo, Wed,
Oct 10:
<I tied a cheap camcorder to the tail of my Savannah and took a short
video of a takeoff and landing. For your reference, the stripes are 150
feet long, I was at about 950 pounds, and the headwind was about 6.>
