3RACING 3.0mm Aluminum Single Servo Arm for Ko Propo/Sanwa - Purple - 3RAC-HKS30F/PU  [3RAC-HKS30F/PU]

Clean upgrade for Ko Propo and Sanwa servos

The 3Racing 3.0mm Aluminium Single Servo Arm provides a tidy, reliable option for pilots running Ko Propo or Sanwa systems. The purple anodised finish gives a subtle custom look while keeping control inputs direct.

Precise response for tighter control

Designed to deliver predictable steering and throttle feel, this aluminium arm helps reduce flex compared with stock plastic horns. That makes small corrections more consistent on all surfaces.

Solid construction with a striking finish

Made from aluminium for strength and repeatability, the arm resists wear through regular use. The purple anodising is durable and keeps the part looking smart between events.
