This is kind of a scary question, Tex.
I think most of us just hooked em up. Most of the fuss was in getting the
rudder on straight. The cables seemed kind of simple.

Tex:
You probably will need a shorter turnbuckle on one side, (I think it is the
right), to get things properly lines up, (pedals to rudder).
They may already shipped a long and short with your kit. If you get to the
point with your rudder cables, and your are out of alignment, then this is
what you will need to do.

[quote="landonp(at)bigpond.com"]Hi Tex
I modified the bracket to give a straight cable line at all positions. The original
bracket tended to kink cable to cable end fitting.
Attached a picture (gives idea but not a great picture)

Speaking as one whose rudder cables are lying loose in the fuselage through lack
of rudder at one end and pedals at the other this is all more than a little
interesting.
First off, a question for Tex. What lead you to make the enquiry in the first
place? Was it problems with getting straight leads on the cables?
Secondly to Bruce. Did you build the original system and find it did not give
a straight lead? If that's the case then it is a change that needs to be made.
If the system is tending to change the direction of the cable as it exits the
rolled swage then the cable is going to break.
Thirdly to Jim. Now, it's late here and my brain has had a hard day but I can't
see what the length of the turnbuckles has to do with the lead of the cables
from the rudder. Can you elaborate?

I have followed the directions in the manual and I find that cable can
not rotate freely in all directions as the rudder goes side to side. The
bracket also will bind and touch the fin depending how it rotates. The
cable end being solid for the first few inches , it can rub on side of
the bulkhead wall . Tex

Hi Tex,
Can all this happen with the cables properly tensioned?

Hi All,
I also was concerned about this due to bending and potential fatigue
failure at the cable end associated with the attachment to the rudder.
I did a lot of tweaking to ensure that the cables did not contact the
aft bulkhead or any other structure. Since these holes where not
installed at the factory I had to locate them myself and then cut them.
At the time, I did not comprehend the nature of the rudder stops as
well. I assumed that they would be like the ailerons and elevator,
metal to metal stops that were built into the flight controls.
I finally resolved my concern over these "issues" by reviewing how much
actual rudder movement would be encountered when taxiing and flying the
aircraft. Since there is no direct nose wheel connection to the rudders
and steering is done primarily by braking via free swivel of the nose
wheel and rudder movement will rarely if ever be much greater than a few
degrees in flight I decided that my concern was "much to do over
nothing." It would be nice to clean this area up some but, I could not
justify the effort involved to do so.
I hope this helps...............Bill with kit #49 in Tucson.

Subject: | Re: rudder cable attachments |
There are a few things about the rudder set up that I think are
'opportunities for improvement' in the Esqual.
I had a 'reasonable' rudder travel based on what was available after
generally dressing up the rudder and the fin/tail and fitting the thing.
After I'd been taxiing a few times and thinking about recovering from
extremes I maximised the travel within the bounds of the structure and
got quite a lot more travel. My main concern was to be able to steer the
plane more effectively using the rudder. The brakes are all well and
good when they work but how about the day one has failed?, or landing on
wet grass?. Crosswind landing with engine out when you can give a burst
of power (I do good nightmares too).
As Bill says unlikely to need much when flying and on a 'normal day' but
why not have what's available?
What the extra travel did do was create more bending stress on the
rudder cable ends as has been mentioned and I've resolved to disconnect
them and loosen of the cable ends in the fixings so they can swing more
effectively and not stress the cable where it goes into the thimble.
That is to slim down the centring rubbers so they don't hold the cable
ends so tight. I don't know if the Lightning is similar but the cable
fixing on the rudder looks alike in the recent picture.
The other thing is the lack of travel stops, the paint will damage in
time where they bump together. I haven't figured that one out yet.
I'd be interested in what 'those that know' think about the travel
issue.
Regards, Clive
