Associated FT Aluminum Servo Horn 25T 15.5mm Arm AS1366

Overview

The Associated FT Aluminum Servo Horn 25T, 15.5 mm (AS1366) is a precision-engineered servo horn designed for RC enthusiasts who demand reliability and performance from their setups. Part of Associated's renowned Factory Team range, this compact aluminium servo horn is built to exacting standards for use with servos featuring a 25-tooth spline configuration. Whether you're building a competitive RC buggy, setting up a race-spec RC truck, or fine-tuning an off-road RC car in the UK, having the right servo horn is crucial for accurate linkage control and responsive handling.

This servo horn features a neat, low-profile design with a 15.5 mm arm length, making it ideal for builds where space is at a premium or where specific geometry demands a shorter horn. The durable aluminium construction ensures excellent longevity whilst maintaining the lightweight properties essential for performance RC applications. Associated's Factory Team components are trusted by serious RC racers and hobbyists across the UK who understand that quality servo horns directly impact steering precision, throttle response, and overall driving dynamics.

The 25T spline configuration (Futaba/Savox compatible) is one of the most popular servo spline standards in the RC hobby, making this horn compatible with a wide range of premium servo options commonly found in competition and high-end RC builds. If you're upgrading your RC model with quality components or replacing a damaged servo horn, the Associated FT Aluminum Servo Horn 25T represents excellent value and proven reliability from a manufacturer with decades of RC engineering expertise.

Key Features

• 25T Spline Configuration — This servo horn is designed for servos with a 25-tooth output spline, which is the Futaba/Savox standard and represents one of the most widely adopted servo spline types in the RC hobby, ensuring compatibility with premium servo options across multiple manufacturers and RC applications.
• 15.5 mm Arm Length — The compact 15.5 mm arm length provides a short, low-profile option ideal for builds where space constraints exist or where specific suspension geometry and linkage angles require a shorter servo horn to function correctly within your RC setup.
• Durable Aluminium Construction — Finished in tough aluminium material, this servo horn offers excellent durability and longevity whilst keeping weight minimal, which is essential for maintaining responsive handling and reducing rotating mass in your RC car, buggy, or truck.
• Precision Engineering — As part of Associated's Factory Team range, this servo horn is manufactured to tight tolerances ensuring precise linkage positioning, which translates directly into improved steering response and more predictable handling characteristics during racing or recreational driving.
• Factory Team Quality Standards — Associated's Factory Team components are purpose-built for serious RC competitors and enthusiasts, offering the same quality and reliability found in race-winning competition builds across the UK RC scene.

Technical Performance

The Associated FT Aluminum Servo Horn 25T delivers the technical performance expected from a Factory Team component. Manufactured from quality aluminium, the horn provides excellent strength-to-weight ratio that minimises additional rotating mass whilst maintaining the rigidity required for precise servo arm positioning. The 25T spline connection ensures secure coupling with compatible servo outputs, whilst the precisely machined 15.5 mm arm length maintains consistency across multiple installations. This servo horn is designed as a direct replacement or upgrade component for RC cars, buggies, trucks and other vehicles that utilise 25T spline servos. The compact dimensions make it particularly suitable for applications where space is limited or where the shorter arm length geometry suits your specific linkage setup. The aluminium material provides excellent corrosion resistance compared to plastic alternatives, making it suitable for outdoor RC use across the UK's varied weather conditions. The engineering and manufacturing precision means that steering input is translated directly and responsively into suspension and steering adjustments, which is critical for competitive RC driving or precision control applications.

Frequently Asked Questions

• Will this servo horn fit my RC model? — Yes, if your RC car, buggy, truck or crawler uses a servo with a 25T (Futaba/Savox) spline configuration, this horn will fit. The 15.5 mm arm length makes it suitable for builds where a shorter horn geometry is required. Check your servo specifications to confirm 25T spline compatibility before purchasing.
• What makes the 25T spline standard so popular? — The 25-tooth spline configuration is the Futaba and Savox standard, making it one of the most widely adopted servo spline types across the RC hobby. Many quality servo manufacturers produce 25T spline servos, giving you excellent options for replacement or upgrade servos across different price points and performance levels.
• Is this servo horn suitable for high-performance RC racing? — Yes, the Associated FT Aluminum Servo Horn 25T is part of the Factory Team range specifically designed for serious RC competitors. Many UK RC racers use Associated Factory Team components in competition setups, confirming its suitability for performance-focused applications.
• What is the difference between a 15.5 mm and longer servo horn? — The arm length determines the mechanical advantage and the physical space required. A shorter 15.5 mm horn works well in compact builds or where specific linkage geometry calls for reduced arm length, whilst longer horns provide greater mechanical leverage. Choose based on your build's space constraints and suspension geometry requirements.
• Can I use this horn on different RC vehicle types? — Yes, servo horns are versatile components used across different RC applications including off-road buggies, stadium trucks, rock crawlers, touring cars and other models. As long as your servo features a 25T spline, this horn is compatible, making it a useful spare to have on hand for multiple RC builds.
