tail lynx cable slack
I tried two different set-ups. First, I made it so the cables were just barely tight with no weight on the tail. When on the ground, the tail spring bends enough that the cables are fairly slack.
I wanted less slack, so I made a second set of tabs about 3/16" shorter. I found that I had only a small amount of slack on the ground, which I liked, but in the air, the cables are tight, and I was concerned about long-term wear and fatigue on the lower rudder hinge from having that steady pull on the bottom of the rudder.
I switched to the single-link system.
