Built from premium machined black aluminium, this servo horn delivers the strength and durability required for demanding RC applications whilst maintaining a lightweight profile that won't unnecessarily burden your servo. The innovative design and engineering behind this component make it a must-have upgrade for anyone looking to enhance their RC car's steering response and reliability.
Key Features
- 4-in-1 Servo Arm Configuration — This unique design allows you to choose from multiple arm configurations by simply rotating the top and bottom arms to your preferred position, giving you the flexibility to run left or right 90° L-shaped arms or a straight double arm setup, eliminating the need to purchase multiple servo horns for different applications.
- Premium Machined Black Aluminium Construction — Crafted from high-quality aluminium, this servo horn provides excellent strength-to-weight ratio, ensuring durability during intense RC car driving sessions whilst keeping servo load to a minimum for optimal performance and servo longevity.
- Secure Side Clamp Design — The innovative side clamp mechanism creates an ultra-tight grip on your servo gear splines, preventing slippage and stripping that can compromise steering precision and responsiveness during crucial moments on the track or trail.
- Machined Lugs for Secure Arm Placement — Precision-machined lugs help secure the arms into place once you've selected your desired configuration, ensuring a solid, immovable fit that maintains consistent steering geometry throughout your driving session.
- Universal Savox and Futaba Compatibility — Specifically designed to fit 25T servo splines on both Savox and Futaba servos, this horn works seamlessly with a wide range of popular RC servo brands commonly used in UK RC cars.
- Fixed Servo Saver Configuration — This horn is supplied as a fixed servo saver or fixed option, meaning it mounts directly to your servo without additional intermediary components, providing direct servo-to-horn connection for maximum steering feel and responsiveness.
Technical Performance
The Fastrax 25T Black Aluminium 4-in-1 Servo Horn represents a masterclass in precision engineering and practical RC design. Machined from premium aluminium, this component delivers exceptional strength whilst maintaining a lightweight profile that won't overburden your servo during high-speed cornering or aggressive terrain negotiation. The 25T spline size is compatible with popular Savox and Futaba servo models commonly found in competitive and recreational RC car setups across the UK. The innovative side clamp design creates an exceptionally tight grip on servo gear splines, a critical feature that prevents the slippage and stripping issues that plague inferior servo horns and can completely ruin your steering precision. The machined lugs work in conjunction with the rotatable arm design to provide multiple configuration options, allowing you to optimise your servo arm length, angle and orientation for your specific vehicle type and driving style. Whether you're running a tight handling stadium truck, a slow-speed technical crawler, or a high-speed off-road buggy, this servo horn adapts to your exact requirements. The fixed servo saver mounting delivers direct servo engagement without the play or flex associated with separate servo saver components, ensuring your steering inputs translate immediately and accurately to your vehicle's front wheels. This is a component engineered for serious RC enthusiasts who understand that the smallest details contribute to overall vehicle performance and durability.

Frequently Asked Questions
- Which servo models are compatible with the Fastrax 25T servo horn? — This servo horn is specifically designed to fit 25T servo splines on Savox and Futaba servo models. Before purchasing, verify that your servo has a 25T spline configuration to ensure proper fitment and secure mounting on your RC car.
- What makes this servo horn different from standard single-configuration horns? — Unlike traditional servo horns that lock you into a single arm configuration, this innovative 4-in-1 design allows you to rotate the top and bottom arms to create left or right 90° L-shaped arms or a straight double arm setup, giving you unprecedented flexibility across multiple RC car types and applications without purchasing multiple horns.
- How does the side clamp design prevent servo stripping? — The innovative side clamp mechanism creates an ultra-tight grip on your servo gear splines, distributing clamping force evenly around the spline rather than concentrating stress on individual teeth, dramatically reducing the risk of spline stripping that commonly occurs with inferior servo horns during aggressive driving or crashes.
- Is this suitable for beginners? — This servo horn is suitable for RC enthusiasts of all experience levels. Beginners will appreciate the straightforward design and universal compatibility, whilst experienced modellers will value the multi-configuration flexibility and premium build quality that allows them to optimise their servo setup for specific driving styles and vehicle types.
- Will this servo horn work on my ready-to-run RC car? — This is an upgrade component designed for vehicles equipped with compatible 25T Savox or Futaba servos. Many UK RC cars, including popular brands like Traxxas, ARRMA, Losi, and others, can be upgraded with this horn if they use compatible servos, making it an excellent choice for enhancing the performance of your existing RC car setup.
- What is the difference between this 4-in-1 horn and standard 2-in-1 or 3-in-1 designs? — The 4-in-1 configuration provides superior versatility by offering more arm positioning options, allowing you to achieve the ideal servo arm geometry for your specific application without compromise, whereas standard 2-in-1 or 3-in-1 designs limit your configuration choices and may not suit every vehicle type or driving scenario.
