Key Features
- 25T Spline Compatibility — This servo horn is engineered for 25-tooth spline servo outputs, which is the standard fitment for Futaba servos across the RC hobby, ensuring seamless compatibility with your existing servo and saving you money on replacements when upgrading components.
- Jumbo Size Design — The jumbo profile provides a larger horn arm, which translates to improved steering geometry and more responsive control inputs, making this ideal for crawlers and precision-driven RC vehicles where control accuracy is paramount.
- Black Aluminium Construction — Unlike plastic horns that can crack, strip or flex under load, this aluminium servo horn offers superior durability and maintains consistent performance across extended RC sessions, delivering longevity that justifies the investment.
- Single Servo Horn Configuration — This is a single-arm horn design, perfect for standard servo installations where you need reliable steering control without unnecessary bulk or weight additions to your RC setup.
- Futaba-Specific Design — Purpose-built for Futaba servo fitments, this horn ensures perfect alignment and engagement with your servo output shaft, eliminating fitment issues and guaranteeing reliable operation from the moment you install it.
- Professional-Grade Quality — Fastrax components are trusted by RC enthusiasts nationwide, and this servo horn carries that reputation for quality, precision engineering and performance that serious RC hobbyists demand.
Technical Performance
The Fastrax 25T Jumbo Black Aluminium Single Servo Horn delivers genuine performance improvements through its engineering and material selection. Manufactured from hard-anodised aluminium, this servo horn resists corrosion and wear, making it suitable for both dry racing environments and the damp British climate that RC enthusiasts often encounter. The aluminium construction provides rigidity that plastic horns simply cannot match—there's no flex under steering load, no play that develops over time, and no degradation from UV exposure. The 25-tooth spline is the industry standard for Futaba servos, and the jumbo size offers increased leverage, which can be particularly valuable if you're running tight steering geometry or need more responsive control input on technical terrain. This servo horn is compatible with both 25T servo savers and fixed installations, giving you flexibility in how you configure your RC car UK setup. Whether you're building a competitive off-road racing buggy, a high-speed stadium truck, or a technical rock crawler, this servo horn will provide the steering precision and durability you need for consistent performance session after session.
