Cool topic. Im glad I get to see how you guys do the pull-pull thing.
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.
A 2-56 pull-pull system would be fine for your .46. You use the 4-40 on 1/4 scale planes.
Depending on your servo direction, you put both top elevator half cable on one side of the servo and both bottom elevator half cable on the other side. I would use the Sullivan Pull Pull systems because they come with threaded clevises and it would be easier to adjust the tension of the cables. Also their cables are coated with silicon so if they rub on each other it won't generate interference.
Hope that helps.
