Cool topic. Im glad I get to see how you guys do the pull-pull thing.

Im building my third plane, a .46 size Giles 202 ( http://www.greatplanes.com/airplanes/gpma0238.html ), and Im wondering how to set this up. The kit comes with instructions for using the standard metal control rod for the rudder and the same type of control rods for each elevator half. I was hoping for something more glamorous and a little lighter (i.e. pull-pull cables for the rudder and maybe the elevator, too.)

What kind of things does this require? I've seen how the servos attach to the cables and what not, but are there any special tools/techniques required? Is there a need for running conduit for the metal wire? Just how much stress can those little wires handle?

I've also heard of 4-40 systems and ??? 6-56 ??? systems or something like that. What is the difference between the two? (I don't really know what Im talking about on this one )

I understand the basics to how the rudder system works, but I don't fully understand how to use this method on a 2-piece elevator. Can you attach the cables running from both halves to the same servo? If so, is this wise/optimal?

I know I just spewed a bunch of questions and any help would be greatly appreciated.
