Let me first say that I have been very favorably impressed with all my
dealings with Zenith. They are always ready to help.
The most difficulty I had building the 801 was in the wiring of the engine
and avionics (not related to Zenith) and in making a workable fuel system
for an injected engine with large amounts of returning fuel. I am very
pleased with the 801 so far.

--> Zenith-List message posted by: ron dewees <rdewees@mindspring.com>
Hi Listers,
I've sorted out a lot of nagging problems during the first annual of
N601TD and now gotten to the secondary squawks that were on the back
burner. I have gotten tired of the rudder pedals hanging forward
sometimes when I get into the plane. Everything is great when your feet
are on the pedals but there isn't any method of tensioning the pedals in
the upright position when you remove your feet.. I've thought about a
small spring with long ends on it to attach to the back of the pedals
and to the lower firewall to keep some tension on the pedals. This
would also keep any overflow of hydraulic fluid from spilling on the
floor from the Matco brake cylinder when it's tilted forward.
What have some of you done about pedal centering, if anything? I
realize that if you get too agressive with a spring or bungee solution
it would affect the rudder trim if not balanced and fairly weak in
tension. Any ideas? Pix?
Thanks
Ron

That must have been a great experience to hear him speak.
I recommend the book "Black Knights" ... better than the movie; although
I do like pretty much anything Fishburn stars in :) The book does take
an abrupt turn in the middle, though.
They were the only unit not to lose a single bomber to enemy fire over
German-occupied territory; although 66 Tuskegee airmen were killed in
escorts. Funny how the b-17 bomber crews didn't see color when they
preferred the Tuskegee escorts over others.
Best part is when the president's wife takes an unplanned detour to the
airfield and insists on a ride in a small plane with a black man as the
pilot. Shocking (for that day and age)! The secret service were crapping
their pants.
Yes, it was a different era and time. There's always room for
improvement, but the fact that we can be so shocked about it today shows
how far things have progressed.

--> Zenith-List message posted by: "T. Graziano" <tonyplane@bellsouth.net>
Andrew,
I also have the dual sticks on my 601XL. In addition to the other comments,
you may wish to check if the stiffness exists without the cables attached.
If so, one possible reason is that you may have inadvertently left out the
6DS-3-2 column bushings, thus providing a clamping force on the sticks or
left out the bushings on the 6-DS-3 - 3 rod ends, causing the rod ends to
contact the sticks or the 6DS-1-6 control horn plate.
My control assembly movement before cables were attached was smooth. I
agree that in-flight, the ailerons on the XL are not "Twitchy", however they
are not excessively heavy on my XL..
Another thing to check for an excessive right wing down is (from a prior
post)
"My spouse asked why the sticks had a left leaning tendency. (this was while
I was building the airplane and after the elevator cables were attached but
not finalized) The lower elevator cable is on the centerline of 6B16-2.
The upper is displaced to the right of the centerline on 6B5-2 - this
creates a built in bias to lean the stick
to the left (left wing down)- unless corrected."

From: "AndrewC" <andrewgcampbell@tiscali.co.uk>
--> Zenith-List message posted by: "AndrewC" <andrewgcampbell@tiscali.co.uk>
Hi there
I'm still going through the test flying of my 601 XL, G-DROO, and the
probleme
du jour is that the ailerons require excessive force to operate in flight.
By
excessive I mean, two hands are required and my test pilot rightly wants it
fixed.
Elevator control is fine by comparison.
My XL has the twin sticks and the flap trim booster mod required by the UK
authorities.
Application of right stick is heavier than left and when right is applied
the ailerons tend to want to settle back half-way towards neutral. Left
aileron behaves normally by comparison but is still heavier than I would
like.
I understand that aileron control on 601s is heavier than in other planes as
a starting point, but this is really too much!
The problem is that I have no idea why they are behaving this way and don't
know
what to change to try and sort it out. Experience of anyone who has the
twin
stick would be much appreciated. The twin stick arrangement appears to have
the torque tube rotating through metal "bearings" (though these are really
just
holes in metal plates) and one delron bearing. This arrangement seems quite
high friction but I'm not sure what lubricant I can use here. Also I can't
understand why right aileron requires more force and is more prone to return
to
neutral than left. Any ideas?! [Rolling Eyes]
Thanks in advance
Andrew

I made a bellcrank attached to a firewall stiffener. So rather than the
linkage going through the firewall to a nose gear, it just attaches to the
bellcrank. Keeps the rudder pedals where they need to be.

I'm at that point myself, wondering how to keep the rudder pedals where they should
be. Of course, it would have been easier if ZAC had included something about
springs in the TD drawings, or if they included the appropriate springs in
their inventory. But nooooooooooo. Anyway, I found some J-3 rudder pedal
springs at B&B in Gardner KS, which, I think, with some modification could fit
right at the outer end of the rudder pedal shaft. If that won't work, the next
step is to fabricate the springs so that they coil around the shaft, pressing
one leg of the spring against the floor, and the other hooked around the pedal's
vertical bar. There has to be someone out there with a flying TD who's
already dealt with this. Suggestions, anyone?

Well after 3 years of not much aviation activity and more on the
side of house building and shift in priority, I'm putting my 601 HDS
for sale.
Pictures are available on the link below for viewing.
Construction according to the plan, I would say 90% completed
but that last 10 takes so long. Anyway, it has a Lycoming O-235
that only needed new rings when I got it and they were replaced.
The engine had very little usage and a Warp drive is on it.
Most of the electrical is done, fuel system to be completed
and I was planning on putting 6 gallons in both luggage compartment.
Most of engine instrumentation completed except for the artificial horizon.
Electric trim tab, wheel pants, 5 points seat belts,
Front lifting canopy, rivets a4/a5, bolts , etc etc
and the plans.
I'm asking 20K $US
You can e-mail me directly at Royerm@tc.gc.ca or call me for questions...

Guys,
Thanks for all the suggestions, will give them all a thorough check through at
the weekend and hopefully will get to the bottom of it. There definitely seems
to be some friction at the torque tube end and I had wondered whether the design
of the elevator attachment might have given it a left tendency sure enough.
When the cables weren't connected everything was fairly smooth so perhaps
it is as simple as cable tension (I certainly hope so). So I'm going to apply
some lube, and progressively go through the connections until I sort this thing
out! Certainly can't keep flying with almost full aileron trim just to maintain
straight and level...!
Cheers
Andrew

Something I've seen on other planes is a very light cable from one pedal
forward to a pulley on the firewall and back to the other pedal. Light and

Andrew,
Don't over tension those cables. I believe 20-25 lbs should be the max
on those. To have more could
likely cause more friction, wear and early deflection on the belcrank
mounts.

Thanks! On that page, we find an older version of the
trim tab. However, a new version is on the XL
pages... I'm surprised to see how big is the XL tab.
Mine is much smaller and already has almost too much

Michael the larger trim tab is for the LSA requirements in which they
are using 0-200's and Jab 3300's and require less stick pressure in full
flap configuration. Your right it is way to much for normal flying
conditions and I would not alter from the original design of the
recessed trim tab. Bigger in this case is not always better, but for the
U.S. Sport Pilot it is necessary and the 601XL plans have evolved to
suit this category.

Thanks! On that page, we find an older version of the
trim tab. However, a new version is on the XL
pages... I'm surprised to see how big is the XL tab.
Mine is much smaller and already has almost too much
authority.

Although the larger trim is too sensitive for level flight, I personally would
stick with the larger trim, but add a SERVO SPEED CONTROL to reduce the sensitivity.
I've been told by some to simply add a resistor, but that would reduce
the power level to the servo, making it weaker as well as slower. The servo speed
control does it without reducing power/strength.
I'll tell you a little inside info on why that tab is so large on the XL.
The LSA requirements state that it must be possible to trim the aircraft for level
flight with full flaps. The first ELSA 601XL (CZAW-built) was modified from
plan to include the larger tab for this reason. That particular aircraft can
be trimmed for level flight with 25 degrees of flaps.
It was a point of contention with Zenair that CZAW deviated from plan on the trim
tab, but it was not a critical item because of the aircraft category (ELSA).
When it came to the subsequent CZAW-built SLSA (more strict rules) Zenair insisted
on the smaller trim tab, as per the plans. As a consequence, the flaps were
purposely limited to only 10 degrees because the trim tab is not adequate enough
for a higher flap angle (according to LSA rules).
Then comes along the AMD-built SLSA, which was extensively flight tested; a job
well done and highly complimented by the FAA. I know the test pilot, so I know
a littlle about the tests they did. Anyway, I can only surmise that the XL plans
were modified to include a larger trim tab as a consequence of the testing
done at AMD. I would imagine more than a few design changes came out of that
work.
So in the end, CZAW had it right in the first place (as far as the trim tab) but
I guess everyone's farts stink except their own. Too bad the SLSA customer got
shafted with a 10 degree flap limit.
