Pull pull or normal push rod
Hi!
Thin fishing wire is best, and lighter than a pushrod. And does not transfer vibration back to the servo eighter!
Carbon fiber rod or aluminum arrowshaft is what I use if I have to use a rod.
In small planes, around 150cm span, I use 10x10mm balsa rods for elevator and rudder were I canīt use wires.
