Dragging up an old thread. My viper will be here in a few days. Now I need some advice. What length titanium turnbuckles are people using for each surface? I am doing swb/clevis servo arms and 4/40 ball links between 2 carbon control horns on the surfaces. I was thinking of using 4/40 all thread incased in carbon but I like the look of the pro links more. Also is 1" servo arms enough or should i go 1.25"? i would think 1.25" would guve more clearance from the skin. Thanks in advance.
