Rudder pull-pull?

Crossing the lines can lead to the greatest differential when the rudder is
deflected.  The latest Fly RC mag has a pretty good article on the subject.

Tom,

I use Kevlar pull lines and cross them to get a good line form the servo to
the exit at the back of the fuse.  I guess if you are using a coated wire
line there should be no problem.

Hi again all,

So what's the verdict with the Rudder pull-pulls? I'm about to cross that
bridge again this evening. This time I was considering crossing over the
wires/chord/trace to get better geometry. I'm a little paranoid about
crossing the wires( should I use the 'metallic' variety) as I think they
might touch using this method. The resulting 'noise' might not be desirable
to the radio.

The Du-Bro stuff is aesthetically pleasing ( small fittings etc) but
stretches. Kevlar is good-just a pain to fit-off and uses the bigger uglier
eyelets and/ but it too stretches ( maybe through the fittings?).

I've now got some SIG .015 C/L cable but I'm not to keen on fitting it
either. It is stainless and un-sheathed. Cant quite work out how to fit it
off. Soldering (soft) has been unsuccessful sofar. Crimping might look too
much like a hit and miss affair.

The servo end ( horns) seems to be another area of concern I have. I've
resorted to making a horn from circuit board to get a 2" spacing and
screwing it to the top of the existing horn ala MK style.

All in all I'm not to comfortable with any of my options...I'm yet to find
THE set up. I too want to eliminate stretch.

What are you guys doing out there in Pattern world ...I know its a silly,
and to some degree an elementary question, but I just need to find a better
way.

Thanks for any ideas or solutions.

Tom
