8 each of our Micro Pull Pull Tension Adjusters. Alows you to loop your pull pull string through a horn then back to this adjuster which can be slipped and locked along the lenght of the cord running to the horn. Works like a tent pole rope adjuster. Use on F3P and other small models with pull-pull control functions. A very difficult part to make by hand simplified for you here.

A pull-pull setup drives a control surface with two opposing cables instead of a single rigid pushrod, a method builders often choose for rudders on larger or scale models. This category collects complete pull-pull systems and the fittings used to set them up and tension them.
Complete Systems
Du-Bro offers pull-pull systems in several thread sizes, including the Micro Pull-Pull System for small models and the 2-56 and 4-40 systems for progressively larger control loads. Heavy duty 2-56 and dual 2-56 versions add capacity for bigger rudders that see more force.
Tensioning Parts
The micro pull-pull tension adjuster set provides a way to fine-tune cable tension after installation, which helps remove slack and keep both sides pulling evenly. Even tension is what gives a pull-pull rudder its crisp, symmetrical response. Setting up both cables to the same tension also keeps the surface centered when the servo is at neutral.
