I'm working on a 601XL fuselage kit and I can't find the brake/rudder
pedal assembly in the box. Does anyone recall if they had to order it
separate from the regular fuse kit. I bought this kit from a friend and
not straight from Zac. I know that there is an option to make it both
left and right brakes instead of just the pilots.

Terry
the trim tab rod can never be long enough.
the speed envelope of the plane almost requires two different trim setting, fine
for high speed and braod for low approach. you will find the trim tab is very
effective in cruise, 130+mph , just a touch will do ya, to on landing, you
will need everything it has, especially if flying solo. the plane trims out perfect
with two pewople aboard.

test pilot noted several things common with other 601XL's such as the heavy
left wing, very sensitive pitch and not enough elevator trim for a hands off
approach with full flaps. All small items that didn't spoil the flying. It was
a fantastic day with the sun coming out just long enough for us to get some
time flown off to chip away at the 40 hours. The engine is still tight and top
speed is indicating in the low 110's (MPH). I expect that to change after
several hours of break-in time and maybe some tweaking of the prop pitch.

Re the trim tab:
Last thursday I flew my 601HDS with electric trim. Got up to altitude and
touched the elevator trim switch for cruise. It went to full down trim with
my finger off the switch. Hit the switch to get up trim and it went all the
way to full up. The spring in the switch seems to have failed.
I believe the reason I can still tell this tale is that I made my trim tab a
bit smaller than the drawings because I had heard it was very sensitive. I
was able to counter the full trim in both directions by pulling/pushing on
the stick and had time to let the trim run to neutral and then turn off the
trim power switch.
Think about it.

N5SL requires full trim up with flaps down and still can't hold a hands-off approach.
Bigger is better. In cruise it requires very little trim. I went from
this:

to this:
http://www.cooknwithgas.com/5_8_05_Trim.jpg
during my build process and I'm glad I did. The flaps require a larger trim tab.

You'd better be really sure you can overcome a runaway trim situation (that

Did Zenith OK that?

Dave - I can overcome it with my BRS. Let's hope it won't come to that. Before
the next flight I'll talk to the test pilot about doing a test to see what the
consequences are with full trim in both directions.
Thanks for the warning!
Scott.

another battery I have as a spare with a direct hookup and see what

Dave,
I also bought the larger trim tab from Zenith after I saw it on their
certified version of the 601, I have read comments by others that had the
same problem as Scott.
I printed out their latest prints of assemblies with part numbers and it
shows the larger trim tab instead of the small one.

Thanks Larry. Mark Sherman sent me this information. Thought I
would post it for the list:
I did some looking at Radio Shacks web site and found
that they have discontinued the noise filter 270-051
with no replacement part.
I found the same part at Parts Express
(www.partsexpress.com) under the part number 265-042.

I took my plane to Sarasota avionics to see what the experts say. By the way Sarasota
avionics is a great shop if you need someone FAA certified to look at
the plane, They are like Zenithair, fantastic customer service. Since I know
enough to be very dangerous on electronics, they wired my plane up when I built
it. What they have found is that the noise is an egnition noise from the
two white wires leading from the alternator. I am going to look at the niose
suppressors you guys recommend since we are all tending to see this problem.
It is interesting Pete at Jabiru took that stance on the noise, a "not my problem"
stance. If some one has a solution or even a band aid, it would benefit for
him to mention it.

Scott and all,
i practiced run away trim problem, and the procedure I came up with is :
Trim problem at cruise-
1- pull back throttle to manauvering speed
2- stick in direction needed to maintain controlled flight.
3- land
Trim problem below cruise speed, same as above.
If practiced, the plane is easy to fly out of trim. Just gets old quick.

I have the 3300 but have not run it yet. I did have a 2200 on another
airplane and it also had the noise.
After much research and talking to HAM operators, the suggestion was to be
sure the wires are the insulated (grounded shield) type. I rewired the
whole instrument panel and had the noise still. Then, one day a radio
expert told me to ground only one end of the shield on the wires. I did.
It solved my radio noise completely. Apparently if the shielded wire is
grounded on both ends you create a "loop" and the radio picks up the noise
just as it does with a non shielded wire.
On my new 3300 I ve run shielded wires EVERYWHERE.. Hopping I dont get the
problem...

Terry,
I use very little if any aileron trim, both sides around neutral,
during flight - maybe I lucked out in rigging, or maybe because I
corrected the below condition I reported on the list on November 11,
2004. I do not know if current drawings have corrected this condition.
Most of my elevator trim is slightly nose up (1 - 2 "marks") during
normal cruise flight.with just me aboard.

I am about to close up my ailerons. My next step will be to install
the
electric aileron trim tab kit. I have a couple of questions for those
who
are already flying with the trim tab option.
1. The 535-mm length of the trim tab seems pretty long to me. I'm
wondering whether that long tab gives too much trim authority. My
question
to those already flying with the trim tab is, "how much of the
available
servo travel do you use in practice? Is it only +/-1 or 2 marks on the
10-mark trim indicator, or do you sometimes go all the way to, say,
+/-4 or
even 5 marks?"

Apparently if the shielded wire is
grounded on both ends you create a "loop" and the radio picks up the
noise
just as it does with a non shielded wire.
This is why Pete will tell you to ground the carby to the engine or a
common ground (make sure engine is grounded). The cables running to
carby for throttle and choke (starting circuit) can act as loops as the
carby is mounted on a rubber tube/sleeve.
Might not solve everyones problem but worth a try.

Before you try suppressors, you might want to try and shield the white wi

ically if this is the issue. If it is the answers ,permanent shielding is a
vailable.

Thanks, Scott and Juan.
It turns out my elevator is already done, with the full-width ZAC trim tab.
What I am interested in now is the electric aileron trim. The control rod
length must be whatever it takes to allow the tab to move +/-25, according
to 6-ATO-1. The aileron trim is designed to level the wings, hands off, not
to trim the pitch.
If I understand Juan correctly, he needs a lot more aileron trim at
approach speed, and the problem is primarily low left wing when flying
solo. That suggests to me that, the earlier post I recall, that suggests it
would be more effective to put the aileron trim tab on the right wing is
probably correct. At a high angle of attack on approach, it seems
reasonable that the aileron would respond much better to the high pressure
flow under the right wing than to the low pressure flow above the left wing.
Has anyone else flown an XL with the electric aileron trim option? If so,
what percent of the aileron trim travel has been used? Are you mostly
raising the left wing?
Thanks for sharing your experience.

Terry,
the forces on low appraoch are both on elevator as well as Aileron. With someone
else in the plane, the forces are negliable. the plane trims better with
two aboard. I calm days or at altitude, the plane trims out with both tabs set
for one pilot. I set the aileron for one guy at runup.

| Subject: | Elevator Trim (was) Aileron Trim Tab Length for 601XL |
Scott,
I would think with the larger elevator trim tab you would be able to
trim to hold airspeed on final (I surely can not do that with my
original "smaller" trim tab and have to hold back pressure with most
flap settings even at full nose up trim).
It appears you installed the trim tab on the right side. I installed my
trim on the left side as per 6T6 dated 02/03. The longer newer 6T6
dated 08/05 also shows the trim on the left side. Is there a reason you
put the trim tab on the right? (The flow swirl from the prop sometimes
favors one side -Does the Corviar turn "backward"?)
I asked one of the Heinz sons at the open house this year about the trim
tab and if they had considered just making the trim tab longer chord
wise, and if I recall correctly, they said they had, but that it would
have not looked as nice.
Has anyone on the list added and extension to the smaller tab? I have
been thinking of taping on an Al metal plate extension for flight test
to see how effective it would be. The down side is that the trim is
very sensitive and for elevator trim during cruise I just quickly "beep"
the trim. If a tab extension works, It might require slowing down the
servo.
Any comments?

N5SL requires full trim up with flaps down and still can't hold a
hands-off approach.
Bigger is better. In cruise it requires very little trim. I went from

When you set the aileron for one pilot, I presume you set it by the number
of marks on the R.A. Allen indicator. How many marks are required in your
A/C with yourself as pilot?

Gentlemen;
There have been many incidents in flight history when similar things happened.
Be very careful in the selection of the switch and the circuit to control it.
If possible the indicator system should warn if an uncommanded changing situation
develops.
I will always favor manual trim. The Piper J-2 system comes to mind as an almost
impossible to mess up system!

Re the trim tab:
Last thursday I flew my 601HDS with electric trim. Got up to altitude and
touched the elevator trim switch for cruise. It went to full down trim with
my finger off the switch. Hit the switch to get up trim and it went all the
way to full up. The spring in the switch seems to have failed.
I believe the reason I can still tell this tale is that I made my trim tab a
bit smaller than the drawings because I had heard it was very sensitive. I
was able to counter the full trim in both directions by pulling/pushing on
the stick and had time to let the trim run to neutral and then turn off the
trim power switch.
Think about it.

larger trim surfaces mean less deflection. larger surfaces with the same deflection
is trouble.
Scott,
You'd better be really sure you can overcome a runaway trim situation (that
I just encountered) with a trim flap that big..
Did Zenith OK that?

when I was still building, I was planning to make the trim on both sides of the elevator, with very limited travel initially. I was planning to use the AeroConversions manual trim control. http://www.sonexaircraft.com/orders/trimfaq.html.
There is no reason why tight linkages and low inital throw limits will not work.
The only down side I could figure was a slight increase in empty weight at
a long mopment arm...

Dave,
I also bought the larger trim tab from Zenith after I saw it on their
certified version of the 601, I have read comments by others that had the
same problem as Scott.
I printed out their latest prints of assemblies with part numbers and it
shows the larger trim tab instead of the small one.

I put an extension on my elevator trim tab. After some trial and error,
I ended up installing a piece of .032 on the tab that gives it about 50%
more chord. I bent the part that sticks out past the original tab
downward about 25 degrees so that it increases my nose up trim but
doesn't have much effect on my nose down trim. It's not pretty, but it
works. I also added a bungee cord to the upper elevator cable that
balances the weight of the elevator so that the trim tab doesn't have to
work against that force as well.

actual I don't. the trim setting is so dynamic, it is relative to speed/ rpm/wieght,
that as long as the trim is set at zero, when installed, you will constantly
be changing it relative to weight, rpm, speed etc. just set to zero pitch
when installed. then fly the plane at various rpm settings during the fly off.
I know for example that when I have full fuel in right wing, and no passengers,
the trim is set at .05 inched above neutral. When I have m y dad in the
plane and equal fuel, it set the plane for zero aileron trim and zero elevtr
trim at take off. once level I trim for levl flight. it is so dynamic, and the
plane is so light, just setting and forgetting is not in the 601's cards.
once trimmed though, it is hands off for the duration of flight so long as the
weights are neutral, or I keep the gas level even.
Sweet flying plane!!

Hey Listers,
Eleven yeras ago when I was flying off the 40 hours on my 601HD I purposly
flew the airplane with the elevator tab at the extreme positions in cruise
to be sure I could over ride it in case of a runaway actuator for the very
reason that Dave experienced. I did it by moving the trim a little at a time
until I had it at full travel in each direction.
I can see where it would scare the sh-- out of you if you weren't ready for
it. That sucker is very effective at cruise, but just nice in the pattern.
Fly careful!

Hi Dan;
Perhaps he is referring to the FAA Form 8000-38 Fabrication/Assembly Operation
Checklist. I attached a copy of the form.
All: Yesterday I went to get my Repairman Inspection Authorization from
the local FSDO. This took over an hour for some reason. Anyway while I
was there, he asked if I had a construction checklist for my airplane
(701). He said Zenith should have provided or made available one.
Apparently this checklist is something you sign or check off each time
you complete an assembly. I can find no such thing. Does anyone have a
clue what he was talking about?

Hi List,
Has anyone checked out the "Safety-Trim Intelligent Servo Controller"
made by TCW Technologies in Emmaus, PA? If it comes close to doing
the job it's supposed to do, I'll be using it on my 601XL when I get
to that point. Their website is: www.tcwtech.com
I'm thankful that you guys who have "been there and done that" are
sorting out this issue now, and the rest of us can benefit from your
experience.

Hi Guys
I'm looking for a set of HDS wings. Been flying my HD for about 3 years now
and I'm looking to decrease the amount of turbulence I currently experienc
e. Most of my flying is in the mountains and it is usually windy and bumpy
and often times uncomfortable flying. Other than that I like the HD wings a
nd the lift they generate. My only concerns with the HDS wings is that summ
ertime density altitude often gets between 4500-5000 feet and with a 912ul
I'm hoping that 2000 foot runways and decent climb will still be manageable
at gross weight. Perhaps vgs will help with that. Anyway if anyone has a
set they are willing to part with please contact me.
Thanks
John

Thanks for the posting to the original document Stan. The attachment that I
made is a Word file that has exactly the same contents as the form in the PDF
but is not as fuzzy (and can be filled in as a text document).

Hi John,
I remember John Sherley in Dyer Indiana had a set of HDS wings that he
wanted to trade for HD wings.
This is probably to comply with light sport stall requirements. He just
flew his this past year and might still be interested.
Try giving him a call at 1-219-322-6935.

Thanks Stan. I am sure this is what the inspector was asking about. I
could not find this in any of my Zenith materials or on their web site
for the 701.

Here's the latest on my situation. I connected my radio directly to
the battery (power & ground) in the aft fuselage but still had the
same whine. I then took a motorcycle battery and connected the radio
directly to it and the whine was completely gone. The radio was
absolutely clear with the engine running. I have ordered an inline
noise filter suggested by several individuals and will let you know
how that turns out when it's installed. Thanks again to everyone who
responded. Jim

| Subject: | Construction sequence for TD cabin floor |
I was hoping one of the TD builders can help me out with construction
sequence....I made it to the end of 6B-8 where the lower front longerons are
installed. Since I am building the TD version, I started referencing section
TD-2 and then I got lost. It seems like the cabin floor and the rear
fuselage have to be mated before the lower front longerons can be installed
because they reference the lower engine mounts as the forward datum and the
gear channel as the rear datum. but the firewall is not installed per the
instructions until 6B11-B. Then it seemed that the predrilled cabin floor
just did'nt seem to line up right. Undaunted I decided to skip this section
for the moment and complete construction of the rudder pedals and master
cylinders. Additionally the firewall is completed to the cleco stage and I
have not installed the engine mounts yet.
So where do I go from here? Do I mate the two sections before installing the
longerons? are the predrilled holes correct for the longerons and i am just
not looking at it correctly?
Any help would be appreciated. You can contact me off-list if you want;

You most likely have a diode out in the alt......
A filter capacitor can't fix that....

Actually the standard is 27. I believe the long wing is increased by 16" on
each for a total of 32". They have a page on it on their site.
http://www.stolspeed.com/content.php?id=48. I am doing the same plus boxing
the root, which gives me a total of 54 more inches of airfoil. No slats and
adding VGs too.

John,
I have an HDS with 912ul. With the density/altitudes that you describe
my experience is that it would be a real struggle at gross weight. I
flew to Mexico Miss. a few years ago and left there when temp was over
90 degrees and high humidity and I struggled to get to 4500 ft. with two
200 lb ers on board.
