Subject: Zenith-List: CH601-HD(S) fuselage assembly
Hello, folks
My aluminum stack is finally starting to resemble an aircraft (if you have
a lot of imagination, that is):
http://www.zenith.aero/photo/img-6058
When I put the front side skins in place (just to have an idea of what it
would look like), I noticed the interference between the side skins, heel
support and floor (the rolled end of the floor).
The attached pics show the offending area.
The instructions simply say "trim as required" (or something like that).
To me, it seems I'll have to remove a semi-circle one or two inches in
diameter - as I haven't seen any comments about this, I am a little
concerned.
I also have looked at a few of the CH601 sites still on-line, but I did not
find any picture or comment that would clarify this.
Thanks in advance for your comments / suggestions
Carlos

Carlos,
I've enclosed 2 photos (one for the right side and one for the left side) of my
HDS in the area you are having problems with. I don't remember having the same
problem you are having. I did have to make the center wing nose skin 3 times
for other problems. I kept leaving too much gap between it and the front fuselage
skins.
Not sure this helps but it lets you look at some more photos.

Like this one.
You ask if I used 10 *mm*, I reply, yessir, 10* cm*.
Reducing the radius will remove a bunch of material and eliminate the

This brings back some memories! Does ZAC still fully support the HDS model?
If you have not already done so I believe there is a modification to use the
new spring gear from the XL/650 on the HDS. I promise you.having done both,
if it is not too late to modify you might want to consider this. The new
main landing gear design is superior to what is on the HDS. Don't get me
wrong, the HDS gear is fine, it is just the new is better. I am not 100%
certain there is a mod, but I think I remember reading about it.

Steve,
I'd take issue with the claim that the new leaf gear is an improvement. It
is for the XL, but I think the strength of the mains on the large center
spar wing have a serious advantage
for the HDS series. The leaf gear flex tends to give the XL an eccentric
wobble. It weighs lots more. The original takes a bit more to install, but
the original gear is superior to the leaf
even if the leaf looks easier to install. If you're building an HDS, stay
with the original design gear. You'll notice the difference when you get in
serious crosswind landings and
also feel the gear stay aligned when you grease it on with one wheel down in
a landing. You stay straight and don't get tossed off center by the design
of the leaf. I've lifted one and didn't like
the heft of it at all. Felt like 50 plus pounds. The original must be at
least half the weight of the new one-piece gear. The wing span of the HDS
won't like the extra weight either.

Hi Larry,
I would agree with everything you write regarding weight. I can't speak to
the cross wind tendencies. With that said having installed both and landed
on both I disagree with a couple of your points.
I believe ZAC changed the design for a reason. And anyone who has followed
my rants knows I do not always agree with ZAC.
The wheels supplied with the new gear are better and are real airplane
tires. Seeing the quality of your craftsmanship I cannot believe you would
disagree with that. The original equipment works fine though.
I have only flown left seat in an HDS two times and XL once. All of my
other time has been right seat in Don Honabach's 601HDS and a few flights in
others. The HDS I built is currently flying in Australia I had to sell it
when I hit a financial brick wall in 2003. I am currently about 85% done
with fuselage on a 650.
I should have clarified my point.but I did say "consider" not that I
necessarily recommend. To each his own. I do believe the design is
superior in theory. In application it might be who prefers which flavor.
As far as the additional weight goes.I have seen guys easily 75 pounds (or
more) overweight talk about not using this or that on an airplane because it
might weigh a half a pound more or less than another piece of equipment.
This conversation always amuses me. Having recently lost 60 pounds
(promptly put 30 back on) I can speak to this exercise as well. Sometimes I
think the best place any of us can lose weight on our airplanes is by taking
it off our own rear ends. I am not suggesting (for even a moment) that
applies to anyone on this list.It is simply something I have observed at
many airplane functions over the years.
I was referring primarily to the install and eventual upkeep. Replacing
those bungees will be a bear when the time comes.

Are you flying into Oshkosh?
EAA Homebuilt Parking is reserving the same parking spaces as we had last
year for us, just north of the Homebuilders Headquarters and north of the
Cannon Camera viewing stand. Again, we are near the Zenith factory display.
Follow the NOTAMS for the signage needed to park your plane. Please print
another sign with the word ZENITH on it. The volunteers parking the planes
will guide you to the reserved Zenith row.
Unfortunately, EAA will not provide a sperate parking spot for Zenigh
Homebuilt Camping. But they said if there is enough interest and if there is
someone who would get there early enough to get a spot in the back, and if
you know how many people would like to camp together, they will make
arrangements to accomidate us. It would be interesting to know how many
people will be sleeping under their wings with their Zeniths this year! If
you plan to, please let me know and we will see if there is enough interest.
Don't forget to confirm your banquet spot right away. Seating lis limited
and you need to confirm as soon as you can. You can get information at the
Zenith display. Jon Croke is donating 3 Zenair Archive CDs ($49 each) for
the dinner. These disks have the entire Zenair Newsletter collection in
.PDF format for easy searching thru all of the past years of the Newsletter.
Thanks Jon!
See you in Oshkosh!
Joe in Oshkosh

Another comment about the "old" gear---When I checked out in Ray
Huffman's HD, I still had a mental visual picture from a 172, and landed
it at 172 height. As a result, I found out that the HD will make
carrier landings very nicely. Exiting the airplane we were both about
two inches shorter........But the plane wasn't.

If you have not already done so I believe there is a modification to
use the new spring gear from the XL/650 on the HDS. I promise
you.having done both, if it is not too late to modify you might want to
consider this. The new main landing gear design is superior to what is
on the HDS. Don't get me wrong, the HDS gear is fine, it is just the
new is better. I am not 100% certain there is a mod, but I think I
remember reading about it.

Carlos,
I've enclosed 2 photos (one for the right side and one for the left
side) of my HDS in the area you are having problems with. I don't
remember having the same problem you are having. I did have to make the
center wing nose skin 3 times for other problems. I kept leaving too
much gap between it and the front fuselage skins.
Not sure this helps but it lets you look at some more photos.

Hi Steve,
I only said the XL gear leaf is not a good solution for the HDS because the
long spar design takes care of landing loads without adding a second
strength component to the belly of the plane.
The XL needs the leaf gear because of the shorter spar of course, but the XL
has a much longer wing than the 23 foot HDS wing, one reason because the
gear is considerably heavier.
Real airplane tires are not determined by manufacturer, but qualifying
specs. I didn't like the original tires that looked more like something off
a wheel barrow either.
By the time you've got the center spar made, you find the rationale for the
gear is also made. I've changed out my bungees on the mains and found it
"fun" as you describe,
but that wouldn't be reason enough to corrupt the design of the HDS main
gear. It rolls true and on compression, it maintains that alignment. The
spread leaf on the XL is
different only by its attachment and is no worse than any other aircraft
with Cessna type gear. I like the 650 and think it's a great plane. I
might have built one if it had been
available at the time, but it is a distinctly different aircraft than the
HDS. The HD long wing climbs twice as fast as my HDS with the same power
and I'd expect the 650 to do that
also. The HDS is fast enough, but weight is a serious consideration when
loading up that short wing.
Respectfully,
Larry McFarland

Hi Larry,
I would agree with everything you write regarding weight. I can't speak to
the cross wind tendencies. With that said having installed both and landed
on both I disagree with a couple of your points.
I believe ZAC changed the design for a reason. And anyone who has followed
my rants knows I do not always agree with ZAC.
The wheels supplied with the new gear are better and are real airplane
tires. Seeing the quality of your craftsmanship I cannot believe you would
disagree with that. The original equipment works fine though.
I have only flown left seat in an HDS two times and XL once. All of my
other time has been right seat in Don Honabach's 601HDS and a few flights in
others. The HDS I built is currently flying in Australia I had to sell it
when I hit a financial brick wall in 2003. I am currently about 85% done
with fuselage on a 650.
I should have clarified my point.but I did say "consider" not that I
necessarily recommend. To each his own. I do believe the design is
superior in theory. In application it might be who prefers which flavor.
As far as the additional weight goes.I have seen guys easily 75 pounds (or
more) overweight talk about not using this or that on an airplane because it
might weigh a half a pound more or less than another piece of equipment.
This conversation always amuses me. Having recently lost 60 pounds
(promptly put 30 back on) I can speak to this exercise as well. Sometimes I
think the best place any of us can lose weight on our airplanes is by taking
it off our own rear ends. I am not suggesting (for even a moment) that
applies to anyone on this list.It is simply something I have observed at
many airplane functions over the years.
I was referring primarily to the install and eventual upkeep. Replacing
those bungees will be a bear when the time comes.

Steve,
I'd take issue with the claim that the new leaf gear is an improvement. It
is for the XL, but I think the strength of the mains on the large center
spar wing have a serious advantage
for the HDS series. The leaf gear flex tends to give the XL an eccentric
wobble. It weighs lots more. The original takes a bit more to install, but
the original gear is superior to the leaf
even if the leaf looks easier to install. If you're building an HDS, stay
with the original design gear. You'll notice the difference when you get in
serious crosswind landings and
also feel the gear stay aligned when you grease it on with one wheel down in
a landing. You stay straight and don't get tossed off center by the design
of the leaf. I've lifted one and didn't like
the heft of it at all. Felt like 50 plus pounds. The original must be at
least half the weight of the new one-piece gear. The wing span of the HDS
won't like the extra weight either.
