3RACING 3RAC-HKS30F/LB 3.0mm Light Blue Aluminium Servo Arm Single for Ko Propo Sanwa  [3RAC-HKS30F/LB]

Track Ready 3RACING 3RAC-HKS30F/LB Servo Arm

This 3RACING 3.0mm aluminium single servo arm in light blue provides a tidy upgrade path for Ko Propo and Sanwa users. It focuses on steady control and reduced flex for more predictable steering inputs.

Built to Balance Strength and Weight

The aluminium construction offers a firmer feel than stock plastic arms while remaining light enough to minimise servo load. The 3.0mm thickness keeps the arm stiff for repeatable response during tight manoeuvres.

Fitment and Typical Applications

Designed to match common Ko Propo and Sanwa servo outputs, this arm is ideal for racers tuning steering or hobbyists wanting a dependable replacement with a clean finish.
