This versatile RC extension lead is perfect for anyone who has struggled with component placement or needed to extend servo leads, receiver connections, or battery interfaces. The 400mm length provides practical reach without excessive cable management issues, making it ideal for tight chassis layouts or separated component configurations. At just £1.33, it represents excellent value for money and is a must-have spare for any serious RC modeller or hobbyist in the United Kingdom.

Built to withstand the rigours of RC motorsport, this JR HD extension lead combines durability with reliability. The heavy-duty male-to-female JR connector ensures secure connections that won't fail during demanding RC sessions, whilst the included connector clip provides an additional layer of security to prevent accidental disconnections. If you're building or maintaining an RC car in the UK or running any JR-compatible RC system, having several of these extension leads on hand is essential for uninterrupted enjoyment of your hobby.

Key Features

• 400mm Total Length — The extended 400mm length (including connectors) provides practical reach between RC components without creating excessive cable clutter, making it suitable for layouts where components cannot be positioned immediately adjacent to one another. This length is measured end-to-end including the connectors themselves, so you get genuine extension without unnecessary overhang.
• Heavy-Duty JR Connector — This extension lead features a male-to-female JR connector with brown, red and orange colour-coded wiring that conforms to the JR standard used across countless RC receivers, servos and battery interfaces. The heavy-duty construction ensures these connectors will withstand repeated connection and disconnection cycles without degradation or poor contact resistance, critical for reliable RC operation.
• 60-Strand Wire Construction — The cable features 60-strand wire which provides superior flexibility and durability compared to cheaper alternatives with fewer strands. More strands mean the wire can bend, twist and flex repeatedly without fatiguing or breaking the internal conductors, essential for RC applications where cables experience constant movement.
• 22AWG Wire Gauge — The 22AWG wire specification ensures adequate current capacity for standard RC servo connections, receiver leads and light-duty power distribution in RC vehicles. This gauge is the established standard for JR extension leads and provides the right balance between current capacity and cable flexibility for most RC hobbyist applications.
• Included Connector Clip — An often-overlooked but invaluable feature, this extension lead ships with a dedicated connector clip that securely holds the lead in place during operation. This prevents accidental disconnections during aggressive driving, racing or when navigating obstacles, providing peace of mind during your RC sessions and eliminating the frustration of mid-run disconnections.
• Compact 1.5mm Outer Diameter — With a slender 1.5mm outer diameter (approximately 2mm measured across the connector), this extension lead takes up minimal space in your chassis or electronics bay, crucial for tight RC car UK builds where every millimetre matters. The compact profile means you can route the lead cleanly without compromising component access or creating cable management nightmares.
• Ready-to-Use Design — This is a completed, ready-to-use extension lead with no assembly required. Simply connect your components and you're ready to go, making it the perfect spares item to keep in your toolbox or pit bag for emergencies or planned expansions.

Technical Performance

The Radient JR HD Extension Lead represents thoughtful engineering for the RC hobbyist. The 60-strand wire construction at 22AWG provides the optimal balance between current-carrying capacity and cable flexibility that RC applications demand. The heavy-duty JR connector design ensures that connection and disconnection cycles—something that happens repeatedly when maintaining or troubleshooting RC vehicles—don't lead to worn contacts or intermittent connections. Built to UK standards and tested in real-world RC conditions, this extension lead handles the demands of both competition-level RC racing and casual weekend bashing. The 400mm length is specifically engineered to provide practical extension without the weight penalty or signal degradation that comes with excessively long cables. The connector clip represents thoughtful integration of a feature that many overlook until they experience their first mid-run disconnection. Whether you're running an electric RC car UK, a nitro-powered machine, or any other JR-equipped RC system, this extension lead will serve reliably across countless sessions.

Frequently Asked Questions

• What exactly is a JR extension lead and why would I need one for my RC car? — A JR extension lead is a cable that connects two JR-compatible components together, extending the distance between them. You might need one for an RC car when your receiver is positioned far from your servos, when you want to relocate a battery pack, or when you need to separate components for better weight distribution or chassis management. The JR connector is one of the industry-standard RC connections, used on receivers, servos, and battery leads across countless RC vehicles.
• Is this extension lead suitable for beginners? — Absolutely. This is a straightforward, ready-to-use component requiring no assembly or technical knowledge. If you can plug in a servo or battery lead, you can use this extension lead. It's an ideal spare to have when you're just starting out with RC cars, as it provides the flexibility to reposition components as you learn optimal chassis layouts.
• Will this extension lead work with my RC receiver and servos? — Yes, provided your RC receiver and servos use the standard JR connector (brown, red, orange colour-coded leads). The JR connector is extremely common across the RC hobby and is used by major manufacturers including Spektrum systems and many other RC brands. Check your component documentation to confirm JR compatibility, but the odds are excellent if you're running any mainstream RC system.
• Can I use this for high-current applications like direct battery connections? — The 22AWG wire specification makes this extension lead ideal for standard servo connections and receiver leads. For heavy-current applications like connecting batteries directly to an ESC, you should verify the maximum current rating matches your application needs, as 22AWG wire is typically suitable for servos and light-to-medium power distribution but not for maximum current battery-to-ESC connections. Always reference your RC system's documentation for proper lead specifications.
• What is the connector clip for? — The included connector clip secures the JR connector in place, preventing accidental disconnections during operation. This is particularly valuable when driving at speed or navigating obstacles where cable movement could otherwise dislodge the connection. It's a simple but effective safety feature that provides peace of mind during your RC sessions.
• How long will this extension lead last? — The 60-strand wire construction is designed to withstand hundreds of connection and disconnection cycles without fatigue or degradation. Built to perform in demanding RC applications, this extension lead will last for years with normal use, making it an excellent investment as a spare for your toolbox.
