What It Is / How It Works

This steering arm is a metal straight horn arm with 25 teeth and a 95mm length. Servo horns are the arms that attach to the output shaft of a radio-control servo and pass its movement to a linkage, so the arm sets the travel a steering linkage receives.

Who It's For / Use Cases

Radio-control hobbyists who build or repair steering systems often keep spare servo arms on hand, so a replacement or extra arm can save a rebuild. Model builders setting up a new steering linkage use arm length to set the geometry of the linkage, and people who run several servo-driven models can match arms by spline count when they stock spares.

How to Use / Care

1. Use it to steer a radio-control model by fitting it as the steering arm on a Futaba standard servo.

How to Choose

Start with the spline tooth count, since the arm has to match the output shaft of the servo it will fit. Metal arms are a common material choice for steering linkages. Compare spline count, length and material together before buying, and match the arm to the servo you already own.
