Frequently Asked Questions

• What is the Futaba servo arm used for in RC vehicles? — The Futaba Alloy Single Servo Arm is used to convert rotational motion from your RC servo into linear control movements. It connects between the servo output shaft and your vehicle's control linkages, allowing you to control steering, throttle, braking, and other functions. Different arm lengths and configurations allow precise tuning of control geometry and servo travel.
• Is this servo arm compatible with all Futaba servos? — This servo arm is designed as a genuine Futaba accessory and will be compatible with standard Futaba servo output shafts. However, we recommend checking your specific servo model's documentation to confirm compatibility, as some specialised servos may require specific arm configurations. As an authorised Futaba retailer, RC Model Shop can provide guidance on compatibility if you're uncertain.
• What does the 38.1mm (1.5 inch) length mean? — The 38.1mm measurement refers to the overall length of the servo arm from the mounting hub to the control point where you attach your linkage rod. This length determines your servo's mechanical advantage and control throw distance. A 38.1mm arm is considered a medium length, suitable for most standard RC applications where balanced control response and servo speed are important.
• Can I use this servo arm on RC cars, trucks, and buggies? — Yes, the Futaba Alloy Single Servo Arm is versatile enough for use across the full spectrum of RC vehicles including RC cars, RC buggies, RC trucks, and other radio control models. Whether you're building a competition RC buggy or a casual RC basher, this arm provides reliable control linkage functionality.
• Why choose aluminium servo arms instead of plastic? — Aluminium servo arms offer superior durability, longevity, and consistency compared to plastic alternatives. The material resists wear from repeated servo cycling, maintains dimensional accuracy over extended use, and provides better resistance to damage from impact or stress. For serious RC enthusiasts who value reliability and precision control, aluminium is the preferred choice.
• Is this suitable for beginners? — Whilst the servo arm itself is straightforward to install, it is recommended for builders aged 14 and upwards with some experience in RC assembly and setup. Beginners new to RC may benefit from purchasing pre-assembled RC vehicles or kits, though experienced builders will appreciate the precision this component offers for custom builds and linkage adjustments.
• How do I install the servo arm? — The servo arm slides onto your servo's output shaft and is typically secured with a small set screw. The exact installation procedure depends on your specific servo model, so we recommend consulting your servo's manual. The arm can then be positioned at the angle that suits your linkage geometry, and control rods can be attached to the control point.
• Can I adjust the servo throw with different servo arm lengths? — Yes, servo arm length directly affects control throw and mechanical advantage. A longer arm provides greater control throw and mechanical advantage but slightly slower response, whilst a shorter arm provides quicker response with reduced throw. The 38.1mm length offers balanced performance for most RC applications.
