Consistent response from the 3RACING 3RAC-HKS30F/RE

The 3RACING 3.0mm Aluminium Single Servo Arm brings a firmer interface to Ko Propo and Sanwa systems. The anodized red finish and accurate machining help maintain repeatable input under race or bashing conditions.

Compatible servos and model types

Engineered for Ko Propo and Sanwa servo splines, this horn suits a wide range of RC cars. It replaces more flexible plastic arms where sharper control is needed.

Practical fitting tips

Fit the arm with the servo at neutral and confirm the linkage clears at full lock. The 3.0mm gauge is chosen to offer a durable connection while keeping weight low for responsive control.

Can this arm handle heavy impacts?

Aluminium arms are stronger than plastics and resist flex, but extreme impacts can still bend metal. Inspect the arm after collisions and replace if deformed.

Does the colour affect performance?

Colour is cosmetic only; the red anodize protects the aluminium and does not change mechanical properties. Choose based on preference and corrosion resistance.

Should I threadlock the mounting screw?

Use a small amount of medium-strength threadlock on metal-to-metal screws if you expect heavy vibration, but avoid overuse to keep future servicing simple.
