FCC;
Pull pull systems are primarily used on Rudder, but can be used on any surface. So it's not isolated to any given area of the Aircraft.

It is a positive feedback system as there is no slop and you can get tremendous throws from a Pull pull system.

there is different methods of setting up a Pull Pull system the one I'll show you is common. But there is others that we use in Larger scale aircraft to alleviate the constant shock on the rudder/Servo. That is using a bellcrank system then hooking the servo to the bellcrank. allowing the bellcrank to absorb majority of the shock.
