RC Model Shop stocks the Radient JR HD Extension Lead because we understand that reliable servo connections are fundamental to safe and enjoyable RC operation. Quality extension leads prevent signal dropout, reduce the risk of servo malfunction, and provide peace of mind during your RC sessions, whether you're practising at your local RC track or bashing in the park.

Key Features

• 900mm Length — At 900mm long including connectors, this extension lead provides substantial reach for complex servo routing in modern RC cars and trucks, eliminating the need for multiple shorter leads or awkward positioning of servo connections within your chassis.
• Heavy-Duty Male to Female JR Configuration — The standard JR servo connector format ensures wide compatibility with RC receivers and servos from all major manufacturers, making this a universal solution for your RC model shop setup across multiple vehicles.
• 60-Strand Construction — The 60-strand wire design delivers superior flexibility and durability compared to lower-strand alternatives, allowing the cable to flex repeatedly without cracking or signal degradation, which is critical during aggressive RC driving and racing.
• 22AWG Wire Gauge — This wire gauge provides the optimal balance of flexibility and current-carrying capacity for servo signals, ensuring stable communication between your RC receiver and servos without voltage drop or signal interference.
• Included Connector Clip — The integrated connector clip securely holds the male and female connectors together, preventing accidental disconnection during intense RC action and keeping your servo connections reliable throughout extended bashing or racing sessions.
• 1.5mm Outer Diameter — The compact 2mm overall product diameter makes this extension lead easy to route through confined spaces within RC chassis, under body panels, and alongside other wiring without creating bulky cable runs or connection points.
• Brown, Red, Orange Colour Coding — The standard servo colour scheme (brown for ground, red for power, orange for signal) ensures proper polarity and compatibility with all standard RC equipment, eliminating confusion during installation or troubleshooting.

Technical Performance

This Radient JR HD Extension Lead represents quality RC engineering focused on reliability and longevity. The 60-strand, 22AWG construction creates a cable that balances flexibility with durability, essential for RC applications where cables are routed through moving parts, bent repeatedly during assembly and maintenance, and subjected to vibration during operation. The heavy-duty materials ensure this extension lead will outperform economy alternatives and maintain signal integrity across thousands of RC driving hours. Whether you're building a custom RC buggy, upgrading an existing RC monster truck, or maintaining a collection of RC vehicles, this lead's robust construction means it will handle the demands of serious RC ownership. The 900mm length positions this as a versatile choice for most RC car, truck, and crawler applications, whilst remaining compact enough to avoid excessive cable clutter. The included connector clip is a practical engineering touch that elevates this beyond basic extension leads, providing security and peace of mind that matters when you're running expensive RC equipment or racing competitively. Signal quality remains consistent throughout the 900mm run, with no noticeable voltage drop or interference at typical servo operating speeds found in modern RC systems.

Frequently Asked Questions

• Is this extension lead compatible with my RC servo and receiver? — Yes, the male-to-female JR connector is the industry standard used by the vast majority of RC servo manufacturers and receivers across the UK market. If your RC setup uses standard JR-format connectors (brown, red, orange), this extension lead will work seamlessly with your equipment.
• What does the connector clip do and why is it important? — The included connector clip securely fastens the male and female connectors together, preventing accidental disconnection during RC operation. This is particularly valuable during intense RC bashing or racing when vibration and movement could otherwise loosen connections and cause servo malfunction or signal loss.
• Is 900mm long enough for my RC vehicle? — At 900mm, this extension provides excellent reach for most RC cars, buggies, trucks, and crawlers. However, if you require multiple servos positioned far apart or have a particularly large-scale RC model, you may need additional extensions or consider running multiple leads. For standard 1/10 and 1/8 scale RC vehicles, the 900mm length is more than sufficient.
• What is the 22AWG wire gauge and why does it matter? — AWG (American Wire Gauge) refers to the thickness of the wire; 22AWG is the standard for servo extensions. This gauge carries servo control signals reliably whilst remaining flexible enough to route easily through RC chassis. It's not heavy enough for main battery leads, but perfect for the low-current servo signal requirements.
• Can I use this with older RC equipment? — If your older RC equipment uses the standard JR servo connector format, then yes, this extension will work perfectly. However, some very vintage RC systems may use different connector styles such as Futaba S-connectors. Check your existing servo and receiver connectors to confirm compatibility before purchasing.
• How does the 60-strand construction improve durability? — The 60-strand construction means the internal wire is made of 60 individual copper strands twisted together, rather than fewer thicker strands. This creates a more flexible cable that resists cracking and maintains electrical conductivity even when bent repeatedly, which is essential during frequent RC assembly, disassembly, and storage.
• Is this suitable for beginners? — Absolutely. If you're new to RC and learning about your first RC car or truck, this extension lead is straightforward to install. The standard JR connectors are foolproof once you understand the colour coding, and the included clip makes secure connection very simple. This is an excellent choice for anyone building or upgrading their first RC setup.
• Will this extension lead lose signal quality over its 900mm run? — No. The 22AWG wire gauge and 60-strand construction maintain excellent signal integrity over 900mm. You won't experience voltage drop or signal interference that would affect servo performance. Signal quality remains consistent throughout the entire length of the extension lead.
