The Fastrax brand is recognised across the RC community for producing high-quality replacement parts and upgrades that extend vehicle lifespan and improve overall handling characteristics.

This single servo horn is specifically engineered to work with 23-tooth servo saver or fixed mounting systems, making it an ideal replacement or upgrade component for models that utilise Sanwa servo specifications. The black anodised aluminium construction provides an excellent balance between lightweight performance and exceptional durability, ensuring that your steering input translates immediately and accurately to your RC model's direction changes. Whether you're running a 1/10 scale buggy, a crawler tackling rocky terrain, or any RC vehicle in the UK that relies on precise servo control, this servo horn represents a cost-effective way to maintain or improve your model's responsiveness.

RC hobbyists understand that servo horns are among the most frequently replaced components on any RC vehicle, particularly when operating in challenging conditions or during competitive racing. The Fastrax 23T Jumbo Black Aluminium servo horn offers exceptional value at just £9.99, making it an affordable spare to keep in your toolbox. The jumbo size design maximises leverage and reduces the chance of stripping or slipping during aggressive steering inputs, which is particularly valuable for high-performance RC buggies, off-road vehicles, and competition-grade setups. Available now from RC Model Shop, this is the servo horn component that RC enthusiasts across the UK trust for reliable performance.

Key Features

• 23-Tooth Spline Design — The 23-tooth configuration is the industry standard for Sanwa servo compatibility, ensuring perfect fitment with your existing servo setup without modification or adaptation. This specification matches the servo saver or fixed mounting systems commonly found on modern RC vehicles.
• Jumbo Single Horn Configuration — The larger size of this servo horn provides increased mechanical advantage and leverage, meaning your steering servo has to work less hard to achieve full directional control. This design reduces the risk of servo stripping and extends the lifespan of your steering servo considerably.
• Black Anodised Aluminium Construction — Crafted from premium-grade aluminium and finished with black anodising, this servo horn combines lightweight properties with exceptional strength. Aluminium is the material of choice for RC components because it resists corrosion, maintains dimensional accuracy, and provides excellent durability even after repeated impacts and hard use.
• Sanwa Servo Compatibility — Engineered specifically for Sanwa servo specifications, this horn guarantees proper fitment and optimal performance with your Sanwa servo unit. Sanwa is one of the most popular servo brands in the RC industry, particularly favoured by serious racers and crawler enthusiasts.
• Direct Replacement or Upgrade — Whether you're replacing a worn or damaged servo horn or upgrading from an older plastic component, this aluminium horn delivers immediate improvement in steering responsiveness and reliability. Many RC enthusiasts upgrade to aluminium servo horns as preventative maintenance before their plastic horns fail.

Technical Performance

The Fastrax 23T Jumbo Black Aluminium Single Servo Horn represents the perfect balance of engineering, materials science, and practical RC experience. Aluminium is selected for servo horns because it offers superior strength-to-weight ratio compared to plastic alternatives, whilst remaining significantly lighter than steel. The black anodised finish provides additional corrosion resistance, which is particularly important if you operate your RC vehicle in wet conditions or in coastal environments where salt spray can degrade components. The 23-tooth spline is the international standard for Sanwa servos, meaning this component will work seamlessly with any Sanwa servo equipped RC vehicle. The jumbo size designation indicates that this horn has a larger overall footprint and throw length compared to standard servo horns, which translates to reduced servo strain during steering inputs and better mechanical efficiency. The single horn configuration (as opposed to multi-horn designs) is the standard for RC vehicles that require simple, direct steering control. This servo horn is machined to precise tolerances to ensure a secure fit on your servo spline with no play or looseness, which is critical for maintaining accurate steering response in competitive racing or challenging off-road environments. Whether you're running an RC buggy, a crawler, or any other RC car in the UK, this component will deliver years of reliable service when properly installed.

Frequently Asked Questions

• Is this servo horn compatible with my Sanwa servo? — Yes, this component is engineered specifically for Sanwa servo specifications with a 23-tooth spline design. This is the standard configuration for Sanwa servos used in RC vehicles throughout the UK and worldwide. However, always verify that your servo has a 23-tooth spline before ordering.
• What is the advantage of aluminium over plastic servo horns? — Aluminium servo horns are significantly more durable than plastic alternatives, offering superior strength whilst remaining lightweight. They resist stripping under load better than plastic, maintain dimensional accuracy longer, resist corrosion when anodised, and are less likely to crack or break during aggressive steering inputs or impacts. Most serious RC enthusiasts prefer aluminium servo horns as standard equipment.
• Will this servo horn improve my steering response? — This servo horn replaces your existing component, so the improvement depends on what it's replacing. If you're upgrading from a worn plastic horn or a horn with damaged splines, you should notice immediate improvement in steering accuracy and responsiveness. The jumbo size provides increased mechanical leverage, which can reduce servo strain.
• What does 23-tooth and jumbo mean? — The 23-tooth specification refers to the spline design that connects to your Sanwa servo's output shaft; this is the industry standard for Sanwa servos. Jumbo indicates that this is a larger-size horn compared to standard configurations, providing greater throw distance and mechanical advantage for improved control and reduced servo wear.
• Is this suitable for competitive RC racing? — Absolutely. Aluminium servo horns like this one are the standard choice for competition-grade RC setups, including buggy racing, truck racing, and off-road competition throughout the UK and internationally. Many race teams stock multiple spare horns because they are frequently replaced components.
• Do I need any special tools to install this servo horn? — Installation typically requires only an appropriately sized hex wrench to remove your existing servo horn and secure the new one. Most RC enthusiasts can complete installation in under a minute once they're familiar with their servo layout.
