This set of ten Z-type steel wire push rods is made for RC airplanes. Each rod measures 18cm in length and 1.2mm in diameter and is used in the connection between the servo and the servo horn or control horn, which is essential for stability and accuracy in flight.
The rods are made of high-quality steel wire, and the listing describes them as durable, flexible and a good fit for an SU-27 KT board RC airplane.
A ten-piece pack is convenient for replacement or upgrade needs, since you can keep spare rods for repairs at the field.
High-quality steel construction: premium-grade steel wire for durability.
Precise dimensions: 18cm long and 1.2mm in diameter.
Servo-to-horn linkage: connects the servo to the control horn.
Pack of 10: enough for a whole airplane plus spares.
Lightweight and durable: strong without adding weight.
A push rod links a servo arm to a control horn on a control surface such as an aileron, elevator or rudder. One end of the rod has a Z-bend that hooks into a hole in the servo arm, and the other end is bent or fitted with a clevis to connect to the control horn. When the servo turns, the rod pushes and pulls the surface.
For a model to fly well, the linkage must have no slop and must be stiff enough not to flex. A thin 1.2mm steel wire is a good match for light foam and KT board aircraft, where loads are small, and a shorter rod is stiffer than a longer one, so cut it to the length you need.
Bend the Z with round-nose pliers, make sure the servo arm hole is only slightly larger than the wire so there is little play, and check that the surface moves freely in both directions without binding.

The rod is 18cm long and 1.2mm in diameter and comes in a pack of 10. The listing does not give the exact steel grade or a package list, so check that the diameter matches the holes in your servo arms and control horns.
Wire this thin can bend permanently under load, so use it on light models and replace any rod that has been kinked.
