The forst thing you need to do is measure and drill small holes in the stabs. Apply thin CA to stiffen holes, then redrill. (see pic for approx. where I drilled holes).

Looking at the plane from the rear (as shown in pic) I basically fed the wire through the bottom portion of the rudder (l to r), then fed it up through the right portion of the elevator, then fed it through the top portion of the rudder (r to l), then fed it down into the left portion of the elevator, then finally, I fed it back through the same hole located on the botton portion of the rudder (l to r). You then pull evenly on both ends of the wire (one exiting out from the left, the other exiting from the right). Be sure not to over tighten. When you are happy with all the alignment (be sure to check perpendicularity of rudder to elevator), apply med/thick CA. As you can guess, it's helpful to have some one else help with this. You could always tack one wire "via" at a time, adjusting as you go along. Hope this helps!

OH! One other mod I did was to physically attach the elevator halves. I simply used a leftover peice of 2-56 wire, bent it, drilled small holes in each elevator half and epoxied. Even though each half is controlled by a separate pushrod, I wanted to assure myself they are always aligned.
