I have just started to put together my A-6 Intruder. I have a couple questions.

1. When I removed the plate for the aileron servo in the wing, I noticed the string that will help thread the aileron extension wire. Looking at the wing near the center plywood root rib, I see no exit on the string. When I pull on the end of the string inside of the servo bay, it is tight.
Where do I cut to find the other end of the string?

2. Should the wing be a one or two pc. wing?

Thanks,

Ed
