Surprisingly, my N7 didn't need turnbuckles. Everything was bang on using the lengths in the manual.
When I built my E5, I also used all the lengths in the manual. During the FBL setup when I went to set zero collective, I moved the stick to center and put my pitch gauge on and it read 0.0 degrees.
Oh, and I'm definitely getting a set of Ralph's new pliers, they look amazing.
