Race-oriented aluminium servo arm for tight control

The 3Racing 3.0mm Aluminium Single Servo Arm is aimed at competitive users who require a low flex solution for Ko Propo and Sanwa compatible servos. The 3.0mm thickness balances stiffness and weight to keep steering inputs precise during aggressive driving.

Setup and tuning advantages

Using an aluminium horn reduces play in the control chain, helping to translate fine transmitter adjustments into consistent wheel or throttle movement. It integrates cleanly with Ko Propo and Sanwa splines to maintain predictable servo geometry for tuning setups.

Durable finish with consistent behavior

Aluminium construction provides a repeatable pivot point under load and better resistance to deformation than plastic options. The anodised purple surface offers corrosion resistance while keeping the arm stable across repeated sessions.

Which race setups benefit most from this arm?

Track and touring car setups that need consistent steering feel under heavy input will see the biggest advantage from reduced horn flex and repeatable geometry.

Any impact on servo centring and calibration?

After fitting, confirm servo centring and re-check endpoints; the stiffer arm preserves geometry so calibration remains stable once set.

Recommended maintenance for competitive use?

Inspect mounting interface and screw torque before each event, and replace the arm if any deformation or slippage appears at the spline interface.
