3Racing 3RAC-HKS26/BU Servo Arm Summary

The 3Racing 2.6mm Aluminium Single Servo Arm for KO Propo and Sanwa systems is an economical metal upgrade for hobbyists wanting firmer steering control. Its blue anodized aluminium construction resists flex and keeps steering consistent during spirited driving.

Performance and Build Quality

Replacing a plastic horn with this aluminium arm reduces deflection under load, giving improved steering precision. It is broadly compatible with servos that match the KO Propo and Sanwa spline pattern and suits on-road and off-road platforms alike.

Mounting Tips and Compatibility Notes

Mounting is quick with basic tools; confirm the 2.6mm engagement and use correct hardware to avoid play. For high-torque servos check spline fit to prevent stripping at the servo output shaft.

Is this arm suitable for high-speed on-road cars?

Yes, its aluminium build reduces flex and helps maintain consistent steering at speed, but always match the arm to a servo capable of handling the loads.

Can I paint or alter the finish?

The anodized coating is durable and can be left as-is; repainting may affect tolerance and is not generally necessary for function.

Should I pair this with metal-geared servos?

For aggressive use or heavy-duty steering it's recommended to use a servo with metal gears to match the durability of the aluminium arm.
