Futaba Brake Trigger Small 4PX 15mm Aluminium Silver RC Transmitter FUTEBB1155

Overview

The Futaba Brake Trigger Small 4PX is a precision-engineered aluminium throttle and brake lever designed for RC enthusiasts who demand superior ergonomics and control from their radio transmitter setup. Whether you're piloting an RC car UK-wide or competing in organised RC racing events, this compact trigger upgrade offers a game-changing improvement over the standard levers supplied with your Futaba 4PX transmitter. Built by Futaba, the company that has been leading the way in radio control since 1962, this brake trigger represents decades of expertise in RC control systems and user experience design.

If you find the standard 18mm or 20mm throttle lever supplied with your Futaba 4PX transmitter too wide for your hand or driving style, the Small Brake Trigger 4PX is the solution you've been looking for. This is not just a minor modification—it's a fundamental ergonomic upgrade that can transform your driving experience, reduce hand fatigue during long racing sessions, and give you the precise throttle and brake control that separates competitive drivers from casual bashers. The compact profile means your fingers sit closer to the trigger mechanism, allowing for quicker, more intuitive throttle adjustments and smoother braking modulation. For serious RC car UK enthusiasts, ready to run racers, and anyone who takes their radio control seriously, this upgrade is an essential accessory.

The Futaba Brake Trigger Small 4PX is particularly popular among drivers who prefer a tighter, more responsive feel from their transmitter, those with smaller hands, or racers who value rapid throttle response in competitive environments. Since 1975, J Perkins—the official UK and Ireland Futaba distributor—has been sourcing the best RC equipment for the UK market, and this brake trigger is stocked by over 70 Futaba stockists across the country. You can trust that you're getting a genuine, fully supported component with expert advice and spares availability right here in the UK.

Technical Performance

The Futaba Brake Trigger Small 4PX represents precision engineering in RC transmitter accessories. The 15mm width positions your fingers closer to the trigger mechanism compared to the standard 18mm and 20mm levers, which dramatically improves throttle modulation, braking response and overall control feel. The aluminium construction ensures rigidity and consistent performance—there's no flex or play in the trigger action, meaning every micro-adjustment you make is faithfully transmitted to your RC vehicle. The silver-finished aluminium is both aesthetically pleasing and practically durable; it resists corrosion and maintains its smooth operation even after months or years of regular use. This is a component designed by engineers who understand that RC racing demands precision, and that precision starts with your transmitter interface. The compact profile is especially beneficial for drivers using the Futaba 4PX in racing environments where rapid throttle adjustments and smooth braking modulation are essential for competitive performance. Whether you're running a ready to run RC car, a competition buggy, or a dedicated racing platform, upgrading to this smaller brake trigger can measurably improve your control and lap times.

Frequently Asked Questions

• Is the Futaba Brake Trigger Small 4PX compatible with my Futaba 4PX transmitter? — Yes, this brake trigger is specifically designed for the Futaba 4PX transmitter and is guaranteed to fit perfectly without any modifications. It is not compatible with other Futaba models or non-Futaba radio systems.
• What's the difference between the small trigger and the standard one supplied with my transmitter? — The standard Futaba 4PX comes with either an 18mm or 20mm wide throttle lever. This small brake trigger is only 15mm wide, making it significantly more compact. This narrower profile brings your fingers closer to the trigger mechanism, improving precision, reducing reaction time, and providing a tighter, more responsive feel that many competitive drivers prefer for racing and performance driving.
• Is this suitable for beginners or only for experienced drivers? — While this component is popular with experienced racers and competitive drivers who value ergonomic control, it can benefit any driver who finds the standard lever too wide or uncomfortable. If you have smaller hands or prefer a more compact trigger feel, upgrading from a beginner-level ready to run RC car to a more serious racing setup, this is absolutely worth considering.
• How difficult is it to install the small brake trigger on my Futaba 4PX? — The installation process is straightforward and does not require any tools or technical knowledge. Simply remove the existing trigger lever from your Futaba 4PX transmitter and replace it with the small brake trigger—it uses the same mounting points and secures in seconds. If you need specific installation guidance, the UK Futaba support team and over 70 authorised stockists are available to assist.
• Will upgrading to the small trigger improve my RC racing performance? — Many competitive drivers report improved throttle modulation, faster reaction times, and more consistent braking control after switching to a smaller, more compact trigger. The ergonomic improvement can reduce hand fatigue during long racing sessions and give you the precise feedback you need for competitive lap times. However, performance improvements are subjective and depend on individual hand size and driving style.
• What is the shipping weight and dimensions of this product? — The Futaba Brake Trigger Small 4PX has an approximate shipping weight of 0.01kg (0.03lb), making it an incredibly lightweight upgrade that can be dispatched quickly and stored easily.
