Reliable Aluminium Servo Arm for 3RACING 3RAC-HKD26/SI

This 2.6mm aluminium double servo arm suits KO Propo and Sanwa servos and is aimed at hobbyists who prioritise steady, repeatable control. The simple aluminium construction keeps focus on reliability during regular use.

Matching and Installation

Specifically cut for KO Propo and Sanwa spline fittings, the arm offers a secure mount and consistent response. It is a direct swap for many stock plastic horns and a sensible upgrade for longevity.

Performance and Weight Considerations

Aluminium combines strength and low mass to reduce wear and preserve handling characteristics. This makes it a practical choice when you want improved durability without a big weight penalty.

Can this arm be bent back to true if damaged?

Minor bends can sometimes be corrected, but aluminium can fatigue. Inspect splines and replace the arm if any stress cracks or permanent deformation are present.

Will this improve steering precision over plastic arms?

Yes, aluminium reduces flex compared with plastic, giving a firmer steering feel and more direct control inputs under normal operating conditions.

Is the finish likely to corrode outdoors?

The silver finish resists general wear, but store your parts dry and wipe them after wet runs to prevent long-term corrosion effects on any metal components.
