Technical Performance
The Futaba Metal Servo Horn 3/4" represents precision engineering in servo control systems. Manufactured from high-grade aluminium, it combines lightweight construction with exceptional durability, making it suitable for both casual RC car enthusiasts and competitive racers across the UK. The 18.5mm (3/4 inch) measurement refers to the effective length of the horn, which is a standard size across many popular servo models used in 1/10 scale RC buggies, trucks, and crawlers. The clamp type design means it grips the servo spline securely, eliminating wobble and ensuring that steering or throttle inputs are transmitted instantly and accurately to your RC vehicle. The black aluminium finish provides excellent corrosion resistance, important for RC cars and buggies that may be driven through muddy terrain, water crossings, or stored in damp conditions. Weighing approximately 0.01kg, this servo horn is negligible in terms of vehicle weight, meaning it will not impact your RC car's balance, speed, or handling characteristics. Whether you're upgrading from a worn plastic horn or building a custom RC setup, this Futaba servo horn will deliver the precision and reliability you need for consistent, responsive control of your RC vehicle.

Frequently Asked Questions
- What is a servo horn and why do I need it for my RC car? — A servo horn is the mechanical arm that connects your RC servo to the steering linkage, throttle mechanism, or other control functions on your RC vehicle. When you move the transmitter sticks, the servo horn translates the servo's rotation into physical movement of your RC car's steering or throttle. Quality servo horns like this Futaba metal design ensure precise, reliable control and won't slip or flex under load.
- Will this Futaba servo horn fit my RC vehicle? — The 18.5mm (3/4 inch) clamp type design is a standard size compatible with most popular servo models used in RC buggies, trucks, and crawlers across the hobby. However, you should verify that your servo has a compatible spline (the ridged shaft connection) before purchasing. If you're unsure, contact our knowledgeable team at RC Model Shop and we'll help you confirm compatibility with your specific setup.
- Why choose a metal servo horn over plastic? — Metal aluminium servo horns like this Futaba component offer significantly superior durability and strength compared to plastic alternatives. They resist bending and flexing under load, which means your steering inputs remain precise and responsive. Metal horns also last much longer, making them better value for serious RC enthusiasts who run their vehicles regularly. The improved rigidity also translates to more predictable handling characteristics in your RC car or buggy.
- Is this servo horn suitable for competitive RC racing? — Absolutely. Genuine Futaba components are used by RC racing competitors throughout the UK and worldwide. The metal construction and precise engineering of this servo horn make it an excellent choice for anyone looking to maintain peak performance in competitive situations. Whether you're competing in off-road buggy racing, stadium truck racing, or crawling events, this Futaba spare part will give you the reliability you need when winning matters.
- How do I install this servo horn? — Installation is straightforward: loosen the clamp mechanism, slide the horn onto your servo's spline shaft, position it at the desired angle, and tighten the clamp securely. Ensure the clamp is tight enough that the horn cannot slip under load, but not so tight that it damages the servo. If you're new to RC setup, our team at RC Model Shop is happy to provide advice on proper installation techniques.
- Will this product work with all Futaba servos? — This clamp type servo horn is compatible with most standard Futaba servo models that feature the common spline shaft design. The 18.5mm size is a popular standard in the RC hobby. To confirm compatibility with your specific servo model, we recommend checking your servo's documentation or contacting us directly — our experienced team can verify fitment for your particular RC setup.
