That "can of worms" is so dead that it must smell to high heaven by now!
Your DAR is blindly ignoring the 20! or so years this design has been flying
with nary a problem with this airleron system. It amazes me the kind of
"expertise" that passes for expertise sometimes.
I'm currently fighting a similar battle on the medical front -- people in
white coats who are SO FAR behind the curve in terms of medical research
they border on malpractice.
It rings back to an earlier question someone on this list once asked after
receiving completely opposite answers regarding the simple question of fuel
pump/ filter arrangements. HOW DO WE DISCERN GOOD ADVICE FROM BAD ADVICE?
Hmmm... I think this is a crucial 'skill' set in aviation, and certainly in
constructing our airplanes, ... and every area of life.
Getting off my soapbox now ;-)

I believe it was at a Sun 'n Fun seminar put on by Chris Heintz where
testing of the hingeless aileron was described: 10,000 cycles at twice
the deflection otherwise limited by the stops with no distress to the
aileron . . . followed by another 10,000 cycles at twice the deflection
after having purposely cut into the aileron an inch or two. Still no
distress and the cut/crack did not progress even without a stop hole
having been drilled at the end of the cut/crack.
That's the best my aging cranium can recall and I certainly stand to be
corrected.

Hello again all:
Thank you to all who responded to my search for a 601 or 701 kit. I realize
most folks on this list are enthusiastic committed builders, so this is probably
the wrong audience, but perhaps someone could give me another idea on where
to look. I have had several responses on my search and am in the process of
evaluating them. What I am really trying to find is a Sports Plane eligible
kit that has some/most/ still in the crate/ work left to go. With the Zenith
products this leaves the 601 xl and HD( possible) as well as the 701. I know
there is a 701 on e-bay and some planes/parts on Barnstormers, but does anyone
now of a way to get in touch with builders who have decided to pursue other
interests? There are lots of kits/plane out there and only a fraction are finished.
Does anyone know if Zenith has a list of clients who want/need to sell?
I can be reached off list at: ncwingless@yahoo.com Thanks again. phill.

++ That's the way Chris described it to me at Oshkosh one year as well. For
clarification to those that might wonder about the words above "purposely
cut into the aileron", the way I heard it from Chris was that having done
all of those deflection tests with absolutely no negative results, he made
an intentional cut (half inch I think he said) into the end of the hingeless
material, then continued the motorized flexing. After about 20 minutes
flexing at the rpm of the motor (I think he said it was around 1700 rpm),
the cut did not progress down the length of the aileron, but worked it's way
diagonally over to the second rivet in from the end,... and stopped right
there. That test, plus Grant's comments about no problems from the use of
this design for 20 years gives me all the confidence I need!

Your DAR should not be a DAR signing off experimental planes. Surely he has
heard of the 601 design and it's track record. How the hell he pretends to be
current in his duties is beyond me. You probably ought to call the FAA on him
and ask them to re-certify him. That should wake him up. Or better yet. Get him
terminated from that position. Good luck on your sign off.

Hello list.
I am looking to put 6.00 X 6 wheels on my 601 XL. I
was wondering if anyone has already done this and has
a "Chris Heintz approved" drawing for a nosewheel fork
that will accomodate the larger wheel size. Thanks
for your help.

Phillip and Others looking for a "Good Deal":
You are looking for a partially completed Zenith aircraft? I have some Good
News! You can get a partially completed airplane directly from Zenith!
Thier phone number is (573) 581-9000.
Just order the kit. That's what I call "partially completed" since some of
us work with flat sheets of aluminum and a set of prints.
Seriously, I don't know why you would want to pick up where somebody else
left off. You don't really know the quality of their work and you have to
start in the middle learning how to assemble a Zenith aircraft, where most
of us learn the skills on simple parts. (Generally you start with the tail
section which is fairly easy to asseble) He may have quit when the going
got rough - I've pondered the idea myself after starting the wings!
If you attend the rudder workshop where ZAC provides a partially completed
rudder (all the parts are made and ready for assembly). You can build the
rudder in two days. TWO DAYS! It's only $300 for this adventure. If you
buy the kit, (Partially Complete Aircraft) you can work just as fast and
complete the airplane in a year or less. (Talk to Brett Ray about this).
Good luck with your airplane search.

I understand those feelings, but they are not realistic, in my experience. When
it comes down to it there is not a Zenith aicraft in every town in the country.
Mine was the first HDS kit in Texas in Feb 93, and they are still scattered
in the Lone Star state. When I contacted the FSDO in Dallas/Ft. Worth, the supervisor
there had no idea what a Zenith was. Mine was certified in 99 and the
inspector had never seen one, though he had been working in aviation for over
twenty years. Their field of operation is broader than most of us realize. They
do have other stuff to do. But like you, with my focus on the Zenith I was
very surprised and a little disappointed for some reason that they were unfamiliar
with our aircraft. d Walker

| Subject: | 601 Aileron Trim |
--> Zenith-List message posted by: "Bob Miller" <drmiller@cvillepsychology.net>
List,
The concensus seems to be that aileron trim is needed for the 601, but I'd sure
like to save the time and expense of an electric aileron trim. . Seems to me
that, if you only have the header tank, aileron trim setting will be constant
for any given weight distribution and would only need to be set once per flight.
If this is true, wouldn't it make sense to make an adjustable trim tab, so that
over time one could learn what angle to set it for a given weight on the passenger
side?
Alternatively, has anyone made a manually adjustable aileron trim?
Thanks,
Bob Miller

List,
I think I finally have the pitch set right on my engine and have had the 701
up 3 times but am not satisfied with the way the engine runs. At idle and
up to about 3,000 RPM's it is very smooth, but from there on up to full power
the engine will run smooth then start to run rough and loose RPM,so and then go
back to running smooth for a short time then get rough again. It has 3.3 hours
, all of the temp's look good and even while doing static run-ups during the
prop pitch stage it doesn't violate any high temperatures.
Any and all suggestions are very welcome at this point. I don't feel good
about taking it up again until this is solved. Working all the little bugs out
is harder than building the plane....

There was an earlier post by a builder who successfully used bungees for
aileron trim. I don't know precisely how he had them attached, but I have
flown the Diamond Katana and it uses a (electric) spring trim on the
elevator. I am not installing the aileron trim option on my XL and may
attempt a spring type trim.

Lowell,
Are you certain that you have enough fuel delivery and no restrictions that would
cause a large pressure drop between the fuel pump and the tanks at full power?
If my memory is correct there was a posting a while back about a fuel system that
had a clear fuel bowl inside the cabin and the operator could see the fuel
boil (auto) at altitude. Although the engine continued to get sufficient fuel
in this case I could see some starvation if there is enough of a pressure drop.
Electrical is another consideration, however I think it would be worse down around
idle where the engine vibration is higher and cause the engine to miss.

When someone hires an EXPERT and pays him hundreds and hundreds of dollars to
look over his experimental plane they ought to do a little research before
showing up to take the money. The DAR here in Wyoming, and there is only one,
gets 500.00 to look at the plane and .40 cents a mile too. My inspection will
cost about 740 dollars. I will make damn sure I get my moneys worth from him.

I have had lots of fun pointing out my hi tech sealed aileron hinges to
various pilots, mostly non builders. They are always intrigued ian
interested. Here's something good they won't find on a factory plane. It
gets their attention!

--> Zenith-List message posted by: "Scott Laughlin" <cookwithgas@hotmail.com>
Fellow Zenith Builders:
I know this is early, but I am trying to make plans to be at Oshkosh this
year and meet up with some friends from other states. I would like to be
there during the ZAC dinner and I don't know when this is traditionally
held.
Does anybody know if this date has been set, or at least when it usually
takes place (Monday night, Saturday night)?
Thank you,
Scott Laughlin

--> Zenith-List message posted by: Elwood140@aol.com
HI, All
Does anyone have better information on which way this gusset is installed?
This is to say, I don't see anything in the plans that tells me if the long
taper or the short taper goes toward the top rear longeron or how far the
gusset extends from the front of the rear fuselage. Maybe I've overlooked
something. I'll bet somebody has been there and done that!

I believe it was at a Sun 'n Fun seminar put on by Chris Heintz where
testing of the hingeless aileron was described: 10,000 cycles at twice
the deflection
That's the best my aging cranium can recall and I certainly stand to be
corrected.
+++ Pretty good memory - the 10,000 measured HOURS of typical aircraft utilization.
..from the November/December 1999, issue 115 of the Zenair Newsletter:
"In a relatively short period, the cycles from the statistics could be applied
to the deflection of the aileron for an aircraft utilization of 10,000 flying
hours. No crack (not even chipped paint) was noticed."

Lowell, I have had the same problem on my 912S on the Savannah, I found one of
my fuel lines split at the clamp, that probably happened by applying to much torque,
anyway at max RPM I would loose 4 to 5 hundres RPM's and also roughness.
Seems at those high RPM's I was sucking in air, so just another item to look
at, Cheers

List,
I think I finally have the pitch set right on my engine and have had the
701 up 3 times but am not satisfied with the way the engine runs. At idle and
up to about 3,000 RPM's it is very smooth, but from there on up to full power
the engine will run smooth then start to run rough and loose RPM,so and then
go back to running smooth for a short time then get rough again. It has 3.3
hours , all of the temp's look good and even while doing static run-ups during
the prop pitch stage it doesn't violate any high temperatures.
Any and all suggestions are very welcome at this point. I don't feel good
about taking it up again until this is solved. Working all the little bugs
out is harder than building the plane....

Lowell,
Have you considered: a) doing a fuel flow test to make sure you have
enough fuel throughput capacity, b) checking your carburetor
synchronization (see the Rotax maintenance manual)?

Sounds ahellofalot better than the wt figures I've seen and would probably put
the empty weight within the CG's limits. How do I get description-specs-options
and prices Thanks Herb e-mail:hjafiske@earthlink.net

Larry,
I puzzled over that gusset for a bit, but found the answer (I think) on
7-F-3, lower left of page, at least on my drawings. It shows the shorter taper
to
the "FRWD" end of things. On page 7-F-5, middle left, there is a top view
which shows the break in the angle coming at the forward end of the top longeron.

Go to page 7-F-5... The longer taper goes to the back, when you get
there (installing the upper tubes from the cabin) the position of the
gusset will be natural. Keep the good work.

Just to let you 701 builders know. A 801 broke right there last year so if
your materials list calls for a aluminum gusset you might want to make it out of
4130 to beef up that area. ZAC has told us 801 builders there is no problem
but I am losing faith in them prettty fast. If my 801 wasn't finished I would
change mine.
