Sharper steering for club and grass runs

The 3Racing 3.0 mm Aluminium Double Servo Arm is a tidy upgrade for Ko Propo and Sanwa users wanting improved control. Its aluminium construction keeps the part light while adding resistance to wear and impacts common in regular use.

Notable features of this 3Racing arm

Material: Durable aluminium reduces flex without adding unnecessary bulk.
Compatibility: Designed to match Ko Propo and Sanwa servo splines for a snug fit.
Color: Red anodised surface gives a neat, track-ready finish.

Aluminium advantages explained

Aluminium offers a reliable balance between stiffness and weight, helping the servo arm hold its shape under sudden steering loads and maintain predictable control feel.

Can I use this on a micro or standard servo?

Fit depends on the servo spline and output diameter. The arm is made for Ko Propo and Sanwa interfaces; confirm physical fit on micro or standard types before installing.

How does a double arm change steering feel?

A double arm increases mechanical leverage, which can make steering inputs feel more direct and controllable, especially during tight turns.

Maintenance advice?

Check for play at the spline and mounting screws, and clean any grit after outdoor runs to preserve the anodised finish and fitment.
