Hi!
Here is how most ailerons controls are set up. With torque rods (in this case Du Bro 1/8" piano wire).
Just follow: "the-rule-of-setting-things-up" that says... The servo arm should always be as short as possible...the aileron (treaded) linkage wire arm as long as possible...this enables the ailerons to be stiffer and you avoid flutter easier. Also it's important that all linkages are set up with a 90degree angle to each other so you get equal deflection (same amount of up and down).
