RE: pull-pull system

A pull-pull system uses 2 cables or pushrods to both sides of your servo control arm and to control horns on both sides of the control surface. It is very positive because: 1. you always have a pull for control movement. There is no flexing of the pushrod in a push movement, 2. you can take up the slack in the system to eliminate all slop in your controls.

It is also very light compared to many other pushrod types.

You'll find this type of control on many pattern, 3D and giant airplanes.
