Overview

The Losi Aluminium Servo Arm 25T (Futaba) is a precision-engineered replacement servo horn designed specifically for RC crawlers and specialist off-road vehicles. This component is essential for RC enthusiasts in the UK who demand reliability and durability in their builds. Whether you're running a scale crawler, rock bouncer, or any RC car UK model that requires a fixed servo arm setup, this Futaba-compatible horn delivers the rigidity and performance you need.

Manufactured by Losi, a brand recognised worldwide for excellence in RC crawler and rock crawling vehicles, this servo arm represents the quality you'd expect from a premium RC equipment supplier. The 25-tooth spline pattern ensures compatibility with standard Futaba servos, making it an ideal upgrade or replacement part for anyone maintaining or rebuilding their RC crawler. If you're looking for a ready to run RC crawler or building a custom setup, having quality servo components like this is crucial to achieving smooth steering and responsive control.

This fixed servo arm is manufactured from high-grade aluminium, providing the perfect balance between lightweight construction and exceptional durability. In the demanding world of RC crawling and off-road racing, a reliable servo arm can mean the difference between completing a challenging course and encountering mid-run failures. The Losi Aluminium Servo Arm is designed to withstand the stresses of aggressive steering inputs and rugged terrain.

Key Features

  • Aluminium Construction — Crafted from high-quality aluminium material, this servo arm offers excellent strength-to-weight ratio, ensuring your RC car UK can maintain agility while handling demanding steering loads without flex or unwanted movement during competition or casual bashing.
  • 25-Tooth Spline Pattern — The 25T spline is the industry standard for Futaba servo compatibility, meaning this arm will fit securely onto your existing Futaba servos without modification, ensuring immediate installation and reliable engagement with zero play.
  • Futaba Compatibility — Designed specifically to work with Futaba servo mechanisms, this component guarantees perfect fitment and performance when used with compatible Futaba servos found in many popular RC crawler models and custom builds.
  • Fixed Configuration — This is a fixed servo arm rather than a servo saver design, meaning it transmits steering inputs directly and rigidly to your steering linkage, ideal for precision crawling applications where responsive feedback and predictable handling are paramount.
  • Premium Losi Engineering — As an official Losi component, this servo arm reflects the brand's commitment to quality and performance, backed by their reputation in the RC crawler and rock crawling community.

Technical Performance

The Losi Aluminium Servo Arm represents a perfect engineering solution for RC crawlers and specialist off-road vehicles requiring durable, reliable steering components. At just the right balance of stiffness and weight, the aluminium construction ensures minimal deflection under load whilst keeping your RC model's weight distribution optimal. The fixed mounting design (as opposed to a servo saver arrangement) provides direct, unfiltered steering response, making this servo arm particularly suitable for precision crawling where you need exact steering positioning and immediate feedback through your transmitter. The 25-tooth spline pattern is the universal standard for Futaba servos, one of the most popular servo brands in the RC hobby, especially amongst crawlers and scale enthusiasts. This means whether you're running a Losi buggy, a ready to run RC crawler, or a custom-built rock bouncer, compatibility is assured. The robust aluminium material resists bending and cracking under the stresses of aggressive steering inputs, rough terrain impacts, and extended use. For anyone maintaining or upgrading their RC car UK setup, this component ensures reliability and consistency in steering performance across all driving conditions.

Frequently Asked Questions

  • Will this servo arm fit my Futaba servo? — Yes, this servo arm is specifically designed for Futaba servos with a 25-tooth spline pattern. This is the standard spline size for most Futaba servo models, so compatibility is guaranteed as long as your servo features a 25T spline output.
  • What is the difference between a fixed servo arm and a servo saver? — A fixed servo arm, like this one, connects rigidly to your steering linkage and provides direct steering response with no give or compliance. A servo saver would have some built-in flexibility to protect the servo during crashes. For precision RC crawling and rock crawling applications, fixed servo arms deliver more predictable handling and better steering feedback, making them ideal for technical courses.
  • Is this suitable for beginners? — This is a replacement servo arm component rather than a complete vehicle, so it's intended for users who already have an RC crawler or off-road vehicle and need to repair or upgrade the steering system. Beginners would typically start with a ready to run RC crawler that already has servo arms installed.
  • Why choose aluminium over plastic servo arms? — Aluminium servo arms provide superior durability and resistance to bending compared to plastic alternatives. They maintain their shape under load and during aggressive steering inputs, which is essential for maintaining consistent handling and preventing the kind of flex that can occur with plastic components in demanding RC applications.
  • What vehicles is this servo arm compatible with? — This Losi servo arm is designed for any RC vehicle using Futaba servos with 25T spline output. Common applications include Losi crawlers, rock crawlers, scale RC models, and custom builds that specify Futaba servo compatibility. Check your vehicle's documentation to confirm servo compatibility before purchasing.
