I can't find a spot ANYWHERE that it calls for paper tubes, I assumed them on my own, unfortunately, I didn't think of it before I glued the two wing halves together which makes for a more difficult installation of the tubes.

But the instructions which are added specifically for the dual servo setup literally say to sheet the top just like the bottom. If I hadn't thought at the last second, I would have been cutting the sheeting off to even get the servo wire from the wing to the fuse. That's the part of the manual that baffles me.
