Overview
The Futaba Alloy Twin Arm 40mm (1.6") Silver servo horn is an essential spare part and upgrade component for RC enthusiasts across the UK who demand precision engineering and reliable performance. Whether you're piloting a high-performance RC car, buggy, or crawler, this compact aluminium twin arm servo horn delivers the durability and lightweight profile needed for responsive control and smooth operation. Futaba has been leading the way in radio control since 1962, and this servo horn reflects decades of expertise in designing components that RC hobbyists depend on for competition-grade performance and everyday bashing alike.
As a servo horn replacement or upgrade, the Alloy Twin Arm 40mm is designed for RC pilots who understand that servo linkage quality directly impacts steering precision, throttle response, and overall vehicle handling. The twin arm configuration provides balanced force distribution and reduced binding, making it an ideal choice for 1/10 scale RC cars, off-road buggies, and touring models where accurate servo actuation is critical. Available in a clean silver finish that complements any RC setup, this Futaba servo horn combines proven engineering with an attractive aesthetic that serious RC enthusiasts appreciate.
Stocking genuine Futaba spares ensures your RC model maintains manufacturer-backed quality and reliability. RC Model Shop is an authorised Futaba retailer, making it easy for UK RC hobbyists to source authentic replacement parts and upgrades that keep their vehicles performing at peak efficiency, whether competing on the track or enjoying weekend bashing sessions in the garden.
Key Features
- Alloy construction — Manufactured from durable aluminium, this servo horn combines lightweight performance with exceptional strength, reducing unsprung mass whilst maintaining the rigidity needed for precise servo control in RC applications.
- Twin arm design — The two-arm configuration distributes forces evenly across both mounting points, minimising servo binding and flex whilst delivering smooth, responsive steering and throttle inputs throughout your RC car's operation.
- 40mm length specification — At exactly 40mm (1.6 inches) in length, this servo horn is engineered to fit a wide range of standard servo mounts on popular RC platforms, making it a versatile spare part for RC enthusiasts with multiple vehicles.
- Silver finish — The polished silver anodised coating provides both aesthetic appeal and corrosion resistance, keeping your servo horn looking sharp whilst protecting the aluminium from moisture and UV exposure during outdoor RC sessions.
- Lightweight profile — Weighing just 0.01kg, this servo horn contributes minimal mass to your RC model's steering or drivetrain linkage, allowing your servo to operate with maximum efficiency and reducing power consumption from your battery.
- Standard compatibility — Designed to work with Futaba servo spline patterns, this horn integrates seamlessly with Futaba receiver systems and servo units used across RC cars, buggies, crawlers, and touring models throughout the UK.
Technical Performance
The Futaba Alloy Twin Arm 40mm servo horn represents the engineering standard expected from Japan's leading RC radio control manufacturer. Precision-machined from high-grade aluminium alloy, every dimension and angle has been calculated to optimise servo leverage, steering geometry, and linkage efficiency across competitive and recreational RC applications. The twin arm configuration eliminates the stress concentration that single-arm horns experience, resulting in reduced fatigue, longer component lifespan, and more consistent performance throughout extended RC sessions. The 40mm length strikes the perfect balance between servo torque multiplication and steering response speed, making it suitable for 1/10 and 1/12 scale RC cars, electric buggies, and touring models. The anodised silver finish provides UV stability and moisture resistance essential for UK outdoor use, where rain, humidity, and variable weather conditions can compromise untreated aluminium components. At just 10 grams, the lightweight construction ensures minimal rotational inertia on the servo, allowing faster reaction times to transmitter inputs and smoother power delivery through your RC model's control linkages. Whether you're competing in UK RC racing events, enjoying casual backyard driving, or maintaining a collection of high-performance RC vehicles, this Futaba servo horn delivers the precision and durability that serious hobbyists expect from genuine manufacturer components.

Frequently Asked Questions
- Will this servo horn fit my RC car or buggy? — This 40mm twin arm servo horn is designed to fit standard Futaba servo spline patterns used on many popular 1/10 scale RC cars, touring buggies, and off-road vehicles. If your model uses a Futaba receiver and servo system, this horn should be compatible. However, we recommend checking your vehicle's documentation or contacting our team at RC Model Shop to confirm fitment with your specific RC platform before purchasing.
- Is this suitable as a spare part replacement? — Absolutely. This servo horn is an excellent spare component to have on hand for any RC enthusiast running Futaba equipment. Servo horns experience wear over time and can be damaged during crashes or high-speed running. Keeping a genuine Futaba replacement means you can quickly restore your RC vehicle to full performance without waiting for repairs, making it essential for competitors and regular RC bashers alike.
- What are the advantages of alloy construction over plastic? — Aluminium alloy offers superior rigidity, strength, and durability compared to plastic servo horns. Alloy horns resist bending and flex under load, providing more precise steering inputs and maintaining consistent geometry even under the high stresses of competitive driving or aggressive off-road RC use. Alloy also offers better heat dissipation from the servo and superior corrosion resistance when exposed to moisture and outdoor UK conditions.
- What is the difference between twin arm and single arm servo horns? — Twin arm horns like this Futaba model distribute forces across two mounting points, reducing stress concentration and flex compared to single-arm designs. This results in smoother servo operation, reduced binding in linkages, and longer component lifespan. The dual-arm configuration is preferred for precision RC applications where steering accuracy and consistency are paramount.
- Can I use this servo horn on other brands of RC models? — This servo horn is specifically designed for Futaba servo spline patterns. Whilst some servo splines are standardised across brands, compatibility cannot be guaranteed with non-Futaba systems. For best results and optimal performance, use this horn with genuine Futaba servos and receivers in your RC setup.
- How should I maintain this servo horn? — Keep the servo horn clean and dry after use, particularly after driving in wet conditions or muddy environments common in UK RC bashing sessions. The anodised aluminium finish resists corrosion, but rinsing with fresh water and drying thoroughly will extend its lifespan. Check regularly for any bending or damage, and replace if needed to maintain precise steering control in your RC vehicle.
