I've followed this thread for a while now and thought I would add a word or
two for what it's worth. The reason Chris puts the cowl inside is because
the cowl is pressurized and pushes out against the fuse skin for a tight fit
in flight. And you only need four fasteners!! Quick to remove!! If you
put the cowl outside it will be necessary to put many more fasteners than
Chris did to hold the cowl tight to the skin.
But those planning a tight, low drag spinner/prop to cowl gap do have a
problem..

Dave,
Sounds like good, solid reasoning to me but as Chris' design grows and guys
stick different engines in the airframes, things can change.
The entire inside of the cowl is probably pressurized for the Rotax and
Subaru installations with the "guppy mouth" standard cowling, but Jabiru
will remind users of its engines that the lower cowl area must have low
pressure to ensure that cooling air travels over the tops of the heads and
cylinder barrels and exits out the bottom. This also facilitates the
airflow through the oil cooler if the cooler is located in the recommended
position. Just ramming air in will not suffice for cooling if it can't get
out and somewhere in Bingelis' books he talks about a formula that dictates
more exit area than intake area - just to create such a low pressure area.
XL builders using the 235 engine will need to fabricate a cooling plenum
atop the engine as will you guys planning the Corvair installation. What
you're doing is making sure the cool air goes where it should. Jabiru
accomplishes this with fiberglass "RamDucts" that fit over each bank of
cylinders.
I watched Bill Morelli take off the top cowl of his HDS/Stratus every
morning we flew to and from SnF. It was easy and he had everything open for
preflight inspection. His cowl goes under the top skin (with a bit of a lip
built in also, I think) and with the large opening of the standard cowl
front he had sufficient "wiggle room" to make it work.
Each installation will require differing approaches.
Regards jeff

I believe that Frank raised a very good point that I
was about to oversee. Thanks Frank.
Perhaps with the stock ZAC cowling and a small spinner
it is not a problem.
But I have a 10" spinner attached to a HP hub (SAE 1
bolt pattern). That will be a custom cowling with a
cowling "plate" about 1/4" behind the hub. So, in
this situation, I now think that it would be
impossible to remove at least the bottom portion of
the cowling.

Hello, listers. I'm about to order the material for my fuel lines (601HD with

Doesn't the Jabiru turn a bit fast for the 701? I was thinking the ideal
prop speed for the 701 was around 2500 RPM. That would make the round beast
just about perfect, although a bit on the heavy side. I would guess the
price is a bit on the heavy side too. With 3: 2 gearing and 110 HP that
engine would undoubtedly produce enough torque to outperform any Jab in a
701. Hey, that's my story----and I'm stickin' to it.
Isn't having all these choices wonderful?

| Subject: | XL wing attachment |
--> Zenith-List message posted by: wizard-24@juno.com
I'm in the process of attaching the wings on my 601XL, and I'm pulling my
hair out trying to figure this out. And anyone who has seen me knows darn
well that I can ill afford to lose any more hair.
The drawing is very unclear as to how best get the wings attached
correctly, and of course the builder's manual doesn't even mention
anything about it. I have the wing spars inserted into the center spar
and temporarily bolted, so that part is done. What I can't figure out is:
1. How do I determine the angle of incidence to use (hope I'm using the
right terms)?
2. How do I assure that the leading edge of the wings are perpendicular
to the fuselage center line? (if that indeed is what I am supposed to
do....). There's some mention of using string lines....but there's no
string length dimensions. It seems to me that running two strings of the
same length from the tail to the wing tips won't ensure that the wings
are perpendicular...that would only ensure that the wings are at the same
angle -- which might not be the correct angle.
I'm rambling here, mostly because I don't know what I'm doing. But this
would seem to be an important step, and I don't want to screw it up. I
fly crooked enough without the help of the plane.
I know the HDS & HD models have a different wing configuration, but
hopefully there's some tidbit of info I'm missing.
Thanks,

I can't speak for the 601 guys but if you did that with the 701 plans you would
have a substantial pile of aluminum that would be suitable for making smaller
parts with. Since the 701 drawings have been converted to CAD there have been
several hundred corrections, most minor some not. It seems that Zenair is getting
a handle on it (the 701) as the last go round was pretty uneventful. Scratch
building and kit building are different animals (I've done both an RV3 and
a Glasair) The scratch builders swap more time and less money for their "kit"
and have little trouble generally making the minor adjustments. Remaking a part
means slipping a piece of alum into the form block and hammering out a new
one in 10-15 min instead of firing off a check to Zenith and gnashing your teeth
waiting on the mailman. OK guys I've said my piece about scratch building,
lets hear from the other side. LOW&SLOW John

Hi Mike. I just guessing here since I am not there
yet but for squaring you could check using pythagorus
theorem from geometry. It only works using right
triangles. If you can
1. measure from a spot on the leading edge to the
centerline of the AC and call that X and (has to be
measured right along the leading edge)
2. measure from the intersection of the leading edge
line with the centerline to a spot on the tail and
call that Y.
Then the measurement from the spot on the leading edge
to the spot on the tail is Z
If the leading edge is in fact perpendicular to the CL
of the AC then Z should be equal to the square root of
(x squared plus y squared) Is the Z measured the same
as the Z calculated?
I am certain there must be a better (simpler) way but
I can't think of one right now. Good luck

I used 3003-0 in 1/4" AFTER the fuel pumps only, which I installed in the
last "bay" of the inner wing between the nose ribs, bolt through the bottom
wing skin. This was as close as I could reasonably get the pumps to the
tanks.
I used 3/8ths rubber hose on the suction side of the pumps.
The 3003-0 forms easily and as long as you don't stand on it will be just
fine. Your only running at 5psi or so anyway.

3003-0 is the stuff to use. It's much easier to work with, cheaper and
plenty strong enough for fuel systems. I am using 3/8" O.D., the chart in
the ACS catalog lists the max working pressure as 520 psi with a safety
factor of 2. It's sold in coils so the shipping will be less also.

So In the HD(S) the center wing section is straight (at least I hope it was)
so If you take two tape measures from the spar (or the rear spar) on the
out board edge to the tail tip and make that dimension the same, the wing
MUST be square to the fuse...This assumes the fuse is straight.
That's what I did and I got it to within a millimeter as accuratly as I
could measure.
I know of at least one plane that is nearly an inch out, and it still flys
just fine....Not good enough for MY plane though.

Subject: Zenith-List: XL wing attachment
--> Zenith-List message posted by: wizard-24@juno.com
I'm in the process of attaching the wings on my 601XL, and I'm pulling my
hair out trying to figure this out. And anyone who has seen me knows darn
well that I can ill afford to lose any more hair.
The drawing is very unclear as to how best get the wings attached correctly,
and of course the builder's manual doesn't even mention anything about it. I
have the wing spars inserted into the center spar and temporarily bolted, so
that part is done. What I can't figure out is:
1. How do I determine the angle of incidence to use (hope I'm using
the
right terms)?
2. How do I assure that the leading edge of the wings are
perpendicular
to the fuselage center line? (if that indeed is what I am supposed to
do....). There's some mention of using string lines....but there's no string
length dimensions. It seems to me that running two strings of the same
length from the tail to the wing tips won't ensure that the wings are
perpendicular...that would only ensure that the wings are at the same angle
-- which might not be the correct angle.
I'm rambling here, mostly because I don't know what I'm doing. But this
would seem to be an important step, and I don't want to screw it up. I fly
crooked enough without the help of the plane.
I know the HDS & HD models have a different wing configuration, but
hopefully there's some tidbit of info I'm missing.
Thanks,

1. If the spar center section was installed properly with the wing jigs, the
angle of incidence will be correct, just align the rear Z with the rear
attach plate.
2. The most important thing is to get the wings attached at the same angle.
The bolts in the spar will hold the wings close enough to perpendicular, a
slight deviation from this angle will make no difference. I measured from
each wing tip to the centerline at a point near the tail and they were
within 1/16" with just the spar bolts installed. I just clamped them at the
rear attach plate and drilled the holes.

What the heck does aluminum lines do to keep the fuel out of the cockpit?????

When I fitted the HDS wings to my HD, I just eyeballed the rivet line from
the wingtip to the fuselage. If that was straight I figured that would be
good..

Dave,
I am many hundreds of hours before tackling this task, but I did find
drawing 6-S-3 that details a 3 step procedure to align and square the wings
relative to the plane.
The drawing is towards the back of the drawing bundle. If you can't locate
it maybe ZAC can furnish.

Glenn,
The short answer to that is no because
the scale is not consistent. I used a plasma cutter
and trimmed the last inch to maintain properties
of the 6061-T6, which does save time in blanking.

Steve,
The light structure of the 701 would make one think by
hanging so much on the nose you'd be better building an 801.
The 701 climbs as good as it's going to with 65-80 hp. Adding
more wt to get HP just increases your glide angle but not much the climb
angle.
And the stress goes way up.

I must have the old version of 6-S-3, because there isn't squat about
details, so maybe I'll check with ZAC top see if there's an update (I
checked the web site and there's nothing there). But many thanks to those
who offered their input -- some very good ideas. I also plan to check all
the RV web sites out there, since I'm told the wings attach in the same
manner as the XL.
