Overview

The RC Overhaul 25T Aluminium Clamp Servo Horn in Red (G-RCO-UN010R) is a precision-engineered servo horn designed for RC enthusiasts across the UK who demand reliability, strength and clean styling in their RC car setups. Whether you're piloting a competitive 1/10 scale buggy, a high-performance touring car, or any RC vehicle equipped with a 25T spline servo, this servo horn delivers the secure linkage control you need for responsive steering and throttle management. Built from premium aluminium with red anodising and distinctive silver chamfered edging, it combines aesthetic appeal with genuine functional advantages that serious RC racers and weekend bashers alike will appreciate.

This servo horn stands out in the crowded RC spare parts market because it addresses a critical need: secure servo horn attachment that won't slip under load. The innovative clamp design means you get the precision of a standard servo horn screw, plus the added security of a locking clamp mechanism that keeps the horn firmly seated on your servo's spline. For RC car UK enthusiasts who've experienced the frustration of a servo horn rotating under hard cornering or aggressive throttle application, this product is a genuine game-changer. The thoughtful engineering—including the hollowed centre for a lightweight, clean look and two distinct mounting points offering 15mm and 19mm throw options—shows that RC Overhaul understands what matters to serious RC modellers.

Available now at RC Model Shop, the RCO 25T Aluminium Clamp Servo Horn is an affordable upgrade that will make an immediate difference to your RC vehicle's steering precision and reliability, whether you're running a brushless touring car, a nitro-powered competition buggy, or any other 25T spline servo application.

Key Features

• Dual Mounting Points — The horn features two different mounting positions at 15mm and 19mm throw, allowing you to fine-tune your steering response and adjust the mechanical advantage to suit your specific driving style, track conditions or vehicle setup preferences.
• Innovative Clamp Design — Unlike traditional servo horns that rely solely on a single screw for attachment, this horn includes a dedicated clamp screw mechanism that tightens after initial installation to lock the horn firmly onto the servo spline, virtually eliminating any possibility of slippage during aggressive cornering or hard acceleration.
• Premium Aluminium Construction — Machined from high-grade aluminium, the horn offers an excellent strength-to-weight ratio, ensuring your servo linkage remains rigid and responsive without adding unnecessary mass to your RC vehicle's steering system.
• Red Anodised Finish with Silver Chamfered Edging — The striking red anodised coating provides both corrosion resistance and visual appeal, while the silver chamfered edges add a professional, factory-quality appearance to your RC car's servo installation.
• Hollowed Centre Design — The strategically hollowed centre reduces weight while maintaining structural integrity, contributing to a cleaner, more refined appearance and helping keep your overall vehicle weight as low as possible for improved performance.
• 25T Spline Compatibility — Engineered specifically for 25T spline servos including Futaba and Savox brands, this horn ensures perfect fitment and reliable connection to your servo output shaft without any play or wobbling.
• Screw and Clamp Fixing System — Installation is straightforward: simply mount the horn using a standard servo screw as you normally would, then gently tighten the clamp screw to add an extra layer of security and peace of mind during high-performance driving.

Technical Performance

The RC Overhaul 25T Aluminium Clamp Servo Horn represents genuine engineering excellence in servo horn design. Measuring 31mm by 7mm, it strikes the perfect balance between functional surface area for secure linkage connection and minimal profile to avoid fouling on chassis components or suspension arms. The use of premium aluminium as the primary material ensures exceptional rigidity where it matters most—at the servo spline interface—while the strategically positioned hollow sections reduce unnecessary weight without compromising structural strength. The red anodised finish provides a protective oxide layer that resists corrosion from moisture, road salt and the general wear and tear of outdoor RC driving in the UK climate. The silver chamfered edging is more than cosmetic; the angled edges reduce stress concentration points that could otherwise lead to premature failure under the repetitive mechanical stresses of servo operation. The dual mounting points at 15mm and 19mm throw give you genuine flexibility in tuning your vehicle's steering ratio and response characteristics—a feature that experienced RC car UK competitors will immediately recognise as valuable. The clamp screw mechanism is the real innovation here: it provides redundancy in the attachment system, meaning even if vibration were to slightly loosen the primary servo screw, the clamp maintains positive engagement with the spline, preventing the catastrophic loss of steering control that can result from a horn rotating under load. This design philosophy reflects professional-grade thinking about reliability and safety in RC vehicle operation.

Frequently Asked Questions

• Will this servo horn fit my servo? — Yes, provided your servo has a 25T spline output. This includes Futaba and Savox servo models, which are among the most popular servo brands in the ready to run RC and competition RC markets across the UK. Check your servo's specifications to confirm 25T spline compatibility before ordering.
• How do I install the RCO 25T Aluminium Clamp Servo Horn? — Installation is simple and takes just a few minutes. First, position the horn onto your servo's spline in your desired orientation, then insert and tighten the standard servo screw as you normally would. Once the horn is mounted, gently tighten the included clamp screw to lock the horn firmly onto the spline. Do not over-tighten the clamp screw; a light, firm tension is all that's needed for maximum security without risking damage to the servo or horn.
• What are the differences between the 15mm and 19mm mounting points? — The 15mm throw position offers a tighter steering ratio with less mechanical leverage, making it ideal for high-speed circuit racing where subtle, precise steering inputs are preferred. The 19mm throw position provides greater mechanical advantage, giving you more servo horn movement for a given servo rotation—useful for technical, tight courses or where you need more aggressive steering response.
• Is the clamp design really necessary? — Many RC enthusiasts have experienced servo horns slipping or rotating under hard driving conditions, particularly in competitive racing where sustained high forces are applied to the servo linkage. The clamp design provides a secondary locking mechanism that makes this problem virtually impossible, giving you reliable, consistent steering performance throughout your driving session without the need for repeated adjustments.
• Will this servo horn make my RC car steering better? — This horn won't change your servo's torque or speed, but it will dramatically improve the reliability and consistency of your steering linkage by preventing the slippage that can occur with standard servo horns. Many UK RC car enthusiasts report that upgrading to a clamp-style horn immediately improves their confidence in the vehicle's steering response, particularly during rapid direction changes or in competitive racing scenarios.
• Is this suitable for beginners? — Absolutely. While the clamp design is appreciated by experienced RC racers, beginners benefit equally from the secure attachment and reduced maintenance requirements. The installation process is straightforward, requiring only a small screwdriver, and the improved reliability means less fiddling with adjustments and more time actually driving your RC vehicle.
• What makes the aluminium construction important? — Aluminium offers an ideal combination of strength and light weight for RC servo horns. It resists corrosion better than steel, is significantly lighter than most alternatives, and provides excellent rigidity to maintain precise steering linkage alignment. The anodised finish adds an additional protective layer that's particularly important for RC cars operated in varying UK weather conditions.
