Technical Performance

The Futaba Alloy Single Servo Arm 20mm (0.8") represents precision engineering in miniature form. Constructed entirely from aluminium, this servo horn combines lightweight construction with the rigidity needed for responsive servo control in your RC car, truck, buggy or crawler. The 20mm arm length provides a compact throw that's perfect for applications requiring fine control geometry without excessive servo rotation. This single-arm configuration is ideal for linkage setups where you need straightforward, direct servo actuation—whether that's for steering, throttle linkage, or specialised control systems on your RC model. The machined finish ensures smooth operation and prevents wear on the servo spline, whilst the robust aluminium material resists the vibration and impact stresses common in demanding RC driving conditions.
