Technical overview of the 3RACING 3RAC-HKS30F/BU servo arm

The 3RACING 3.0mm aluminium single servo arm is a performance-oriented component for KO Propo and Sanwa servos. Its machined profile and anodized surface provide a balance of stiffness and durability suitable for competitive tuning.

Material and handling characteristics

Aluminium construction reduces elastic deformation under steering loads, improving repeatability in high-precision runs. The 3.0mm thickness offers a compromise between weight and rigidity for consistent handling behaviour.

Application and setup considerations

Intended for use on steering systems where reduced flex and sharper feedback are required, this arm fits a range of RC platforms. Check spline compatibility and assess servo torque capacity when integrating into a tuned setup.

Fitting protocol and service checks

Install with the correct spline alignment and torque settings to avoid micro slip. Inspect mounting interfaces periodically and replace if you observe visual deformation or excessive wear to preserve steering accuracy.

What spline types are supported by this arm?

It is designed for the common KO Propo and Sanwa spline patterns; verify the spline count and engagement profile on your servo to confirm fit.

How should I assess servo load after upgrading?

Monitor servo temperature and current draw during test runs. A stiffer arm can increase peak torque demands, so ensure the servo operates within safe thermal and current limits.

Are there recommended fastener specifications?

Use OEM-length screws and appropriate grade hardware; avoid overlong fasteners that can bottom out. Apply moderate torque and consider a thread locking compound if vibration is high.
