Performance-Focused 3RACING 3RAC-HKS30F/LB Servo Arm

The 3RACING 3.0mm single servo arm in light blue is aimed at racers and tuners seeking a firmer, more direct connection between servo and linkage. Its aluminium construction reduces compliance to provide repeatable steering inputs under load.

Material Choice and Control Characteristics

Using 3.0mm aluminium yields a low-mass arm with increased stiffness versus stock plastic parts. This lowers control latency and helps maintain accurate wheel position during dynamic steering events.

Installation Notes and Application

Designed for Ko Propo and Sanwa spline interfaces, the arm is suitable for setups where precise steering geometry and minimal slop are priorities. Check spline compatibility and mounting orientation to achieve desired throw and response.

What advantages does 3.0mm aluminium give over plastic horns?

Aluminium reduces flex and improves repeatability under load, which helps maintain consistent steering geometry during aggressive inputs or high torque situations.

How should I set link length when using this arm?

Start with your usual steering throw and adjust link position on the arm to fine-tune sensitivity. Small changes at the arm can noticeably alter steering ratio and response.

Is there risk of spline wear with aluminium arms?

Aluminium arms themselves are robust, but inspect the servo output spline for wear, especially with high-torque servos. Use correct hardware and avoid excessive side loads.

Can I combine this with servo savers?

Yes. If using a servo saver, ensure the arm mounting and saver function together without binding to preserve durability and protect the servo from impact loads.
