Race-Oriented Servo Arm for Precise Steering

The 3Racing 3RAC-HTS3018/RE servo arm is crafted to support focussed steering geometry adjustments on Tamiya platforms. Manufactured from red anodised aluminium, the single-hole servo saver horn reduces play and preserves predictable feedback under load. The 18mm height is selected to deliver useful leverage while keeping mass low for responsive control inputs.

Technical Highlights for Tuners

  • Material: Anodised aluminium chosen for consistent stiffness and a durable surface finish.
  • Compatibility: Built to interface with Tamiya single-hole servo saver configurations common in race setups.
  • Design: Single-hole layout to simplify alignment and reduce variability in steering geometry.
  • Height: 18mm to balance mechanical advantage with compact packaging for precise tuning.

What setup changes should I expect after fitting this arm?

Expect a slight shift in steering ratio due to the 18mm height; retune end points and dual rates to achieve the desired steering sensitivity.

How does this arm affect steering feedback?

The aluminium construction reduces flex compared to plastic arms, delivering firmer, more consistent feedback that helps drivers make finer corrections.

Any tips for installation in a race car?

Ensure zero slop at the servo spline and verify horn centring before finalising servo horn torque; small shims can be used to tune linkage geometry.
