The purple 3RACING 3.0mm Aluminium Single Servo Arm is built for hobbyists who want a clean, reliable servo connection on Ko Propo and Sanwa units. Its slim aluminium construction keeps moving mass down while offering a stable control point for steering or throttle linkages.

Strength with light weight

Constructed from aluminium, this arm resists wear and stays rigid under load while remaining light enough to avoid slowing servo motion. The 3.0mm thickness provides a consistent junction for precise input delivery and helps keep steering predictable through repeated use.

Fits a range of setups

While optimised for Ko Propo and Sanwa splines, this arm works well across many 1/10 and similar scale platforms where that mounting pattern is used. It is a sensible choice for racers and weekend trail rigs that need dependable aluminium hardware.

Can I use this on high torque digital servos?

Yes, aluminium arms are commonly paired with high torque digital servos. Ensure the spline matches and consider servo saver or geometry to absorb heavy impacts.

Will the purple finish wear off with use?

Anodised finishes can show light wear at contact points but are generally durable. Normal use will cause minimal cosmetic change, but heavy rubbing or crash damage will affect the finish.

Is this arm compatible with racing trim adjustments?

Yes, the precise machining and standard hole layout make it straightforward to use when testing different throw and centering setups on Ko Propo and Sanwa servos.
