3RACING 3RAC-HKD30/RE 3.0 mm Red Aluminium Double Servo Arm for Ko Propo and Sanwa  [3RAC-HKD30/RE]

Precision steering control for club and track

The 3Racing 3.0 mm Aluminium Double Servo Arm is tailored for Ko Propo and Sanwa setups and delivers a solid upgrade for drivers wanting crisper steering. Its aluminium build keeps weight low while offering the toughness needed for regular racing and practice sessions.

Main attributes of the 3Racing servo arm

• Material: Lightweight aluminium construction balances rigidity with minimal mass for consistent responses.
• Compatibility: Engineered to mate with Ko Propo and Sanwa servo interfaces for reliable fitting and alignment.
• Color: Bright red anodised finish gives a race-ready look and easy visual identification.

Why aluminium improves servo performance

Aluminium gives a strong strength-to-weight outcome, helping the arm resist bending under load while keeping inertial weight down. That means steadier steering during sharp inputs and reduced risk of deformation in demanding use.
