The 3RACING Futaba Single Arm 3.0mm V2 in black gives a compact option for sharpening steering response on RC cars. The servo gear hole to ball end hole spacing is 25mm, which helps reduce throw for finer steering inputs.
This arm aligns cleanly with compatible Futaba servos to deliver predictable steering input and minimise unwanted play. It holds up well under typical club and park conditions.
Ensure correct seating on the servo spline and tighten the securing screw to prevent movement. Periodic checks and light maintenance will keep the part performing reliably.
