Overview
The Fastrax Pre-Assembled Throttle/Brake Linkage Set Blue (FAST440B) is an essential upgrade for any 1/8th scale RC enthusiast looking to optimise their vehicle's throttle and brake response. Whether you're running a nitro-powered RC car UK model, experimenting with linkage tuning, or simply want a reliable, ready-to-use solution, this pre-assembled linkage set takes the guesswork out of one of the most critical setup adjustments in RC motoring. Pre-assembled and ready to adjust, this Fastrax Pro linkage set represents a must-have component for serious hobbyists who demand precision and quality in their RC vehicle builds.
Fastrax has engineered this throttle and brake linkage set with meticulous attention to detail, understanding that proper linkage setup can dramatically affect throttle response, brake balance, and overall vehicle control. Rather than spending hours calculating angles, measuring distances, and test-fitting components, you get everything pre-assembled and tested, allowing you to focus on fine-tuning rather than basic assembly. This is particularly valuable for those new to RC car tuning or for experienced drivers who want to save time on setup days at the track or bash site.
The set comes finished in a striking blue colour and features a heavy-duty horn constructed with an aluminium centre, combining strength with controlled weight. The inclusion of optional servo inserts means you can adapt this linkage set to work with different servo spline patterns, making it compatible with a wider range of servo brands and models commonly used in the UK RC community.
Key Features
- Pre-Assembled Design — Rather than requiring complex assembly and calculation, this linkage set arrives ready to install and adjust, eliminating guesswork and reducing setup time significantly. This is a game-changer for drivers who want to spend more time driving and less time troubleshooting linkage geometry.
- Heavy-Duty Horn with Aluminium Centre — The horn features a reinforced design with an aluminium centre that resists bending and maintains consistent linkage geometry even during aggressive driving or impacts. Aluminium construction keeps weight to a minimum whilst providing the strength needed for demanding RC applications.
- Optional Servo Inserts — Multiple servo insert options are included, allowing you to adapt the linkage set to fit virtually any servo spline pattern. This versatility means you're not locked into a single servo brand and can upgrade or swap servos without needing a new linkage set.
- 1/8th Scale Optimisation — Specifically engineered for 1/8th scale RC vehicles, this linkage set is sized and geared for the throttle and brake demands of this popular class, ensuring proper throw and response characteristics.
- Throttle and Brake Combined — A single integrated linkage set handles both throttle and brake functions, simplifying your vehicle's servo setup and reducing the number of individual components you need to manage and maintain.
Technical Performance
The Fastrax Pre-Assembled Throttle/Brake Linkage Set has been engineered with precision and reliability as core priorities. The heavy-duty horn featuring an aluminium centre ensures that the critical connection point between your servo and the vehicle's throttle/brake mechanism remains rigid and responsive under load. The aluminium construction provides an ideal balance between weight and durability—critical factors in 1/8th scale RC vehicles where unsprung weight affects handling and performance. The pre-assembled linkages maintain consistent geometry straight out of the box, eliminating the inconsistencies that can arise from field assembly. The optional servo inserts represent thoughtful engineering, recognising that RC enthusiasts across the UK use a variety of servo brands (Spektrum, Futaba, Savöx, and others) and spline types. Rather than forcing you into a single servo choice, Fastrax has equipped this set to work with multiple configurations. For 1/8th scale applications—whether you're running nitro-powered vehicles or exploring electric conversion—linkage setup remains one of the most important tuning variables affecting throttle response consistency and brake modulation feel. This pre-assembled approach delivers a professional baseline that you can then fine-tune through adjustment rather than starting from scratch.

Frequently Asked Questions
- Is the Fastrax FAST440B compatible with my RC car? — This linkage set is designed for 1/8th scale RC vehicles and features multiple servo inserts to accommodate different servo spline patterns. Check your vehicle's scale (1/8th) and servo type before purchasing to ensure compatibility. The optional servo inserts make it compatible with most major servo brands used in the UK RC market.
- What makes pre-assembled linkages better than building my own? — Pre-assembled linkages eliminate measurement errors and geometry miscalculations that can cause inconsistent throttle response or brake feel. This set arrives tested and optimised, letting you focus on tuning rather than troubleshooting basic assembly issues. For beginners especially, this removes a significant learning curve from RC car setup.
- Can I use this with different servo brands? — Yes, the optional servo inserts included in this set allow you to adapt the linkage to work with various servo spline patterns. This flexibility means you're not locked into a specific servo brand and can use servos from manufacturers like Spektrum, Futaba, Savöx, and others commonly available in the UK.
- Why is the aluminium horn important? — The aluminium horn provides a lightweight yet rigid connection point between your servo and the throttle/brake mechanism. Aluminium resists bending and maintains consistent geometry even during aggressive driving or minor impacts, ensuring your throttle response remains predictable and reliable.
- Is this suitable for beginners? — Absolutely. Pre-assembled linkages are ideal for beginners because they eliminate the complexity of calculating linkage geometry and assembling components from scratch. You can install this set and begin fine-tuning immediately, making the learning curve much gentler for those new to RC car setup and tuning.
- What colour options are available? — The Fastrax FAST440B is supplied in blue, a striking colour that complements many 1/8th scale RC vehicle builds and is easily visible during operation.
