Race Oriented Servo Arm for Tamiya Chassis

The 3Racing 3RAC-HTS30/BU performance servo arm is specified for Tamiya layouts where consistent, repeatable steering input is required. Its blue aluminium body provides a precise alternative to stock plastic horns for drivers focused on setup and tuning.

Technical Overview

Machined from aluminium to reduce flex at the servo horn interface, the single-hole configuration maintains a familiar mounting footprint for easy replacement. The geometry is intended to retain original horn offset while improving control stiffness.

Performance Impact

Switching to an aluminium arm tightens the control chain between servo and linkage, improving steering resolution and feedback. This part is suitable for competitive club racing and serious chassis tuning where predictable inputs matter.

What should I check before fitting this arm?

Verify the servo spline type and hole alignment against the original horn. Confirm screw length and retaining method to avoid preload or binding on the servo shaft.

How does this affect setup tuning?

With reduced horn flex the steering becomes more immediate, which can require small trims to endpoints and dual rates to achieve desired mid corner balance.

Is this suitable for competition use?

Yes, it is aimed at competitive users who need repeatable steering response, though drivers should pair it with appropriate servo strength and proper installation practices.
