Overview
The Radient JR Twisted HD Extension Lead with Clip 100mm (RDNAC010220) is an essential accessory for anyone building, maintaining or upgrading RC models in the UK. This heavy-duty male-to-female JR servo extension lead is specifically designed to provide neat, secure wiring connections in RC cars, trucks, helicopters and other remote control vehicles. Whether you're a serious RC enthusiast setting up a competition rig or a weekend basher looking to extend servo connections for better cable management, this extension lead delivers reliability and durability that RC hobbyists depend on.
Built with premium materials and engineering, the Radient JR extension lead uses high-quality twisted wire construction and includes a convenient connector clip to keep your plug firmly in place during operation. The 100mm length is ideal for mid-range servo connections without excessive cable bulk, making it perfect for applications where space is at a premium inside RC model chassis. The JR connector standard is one of the most widely used servo connector types across the RC hobby, and this lead maintains the correct colour orientation (Brown/Red/Orange) to ensure straightforward, error-free installation every time. Recommended for ages 14 and upwards, this is the kind of quality component that serious RC car enthusiasts and professional racers choose when building their rigs in the UK and beyond.
RC Model Shop stocks genuine Radient products, and the JR Twisted HD Extension Lead is a genuine, authorised component that meets the standards expected by the RC community. Whether you need a single extension lead for a quick repair or several for a complete rebuild, this product offers outstanding value and proven reliability that will serve your RC models for years to come.
Key Features
- 100mm Length — At exactly 100mm including connectors, this extension lead is long enough to route servo connections neatly around your RC model's chassis without creating excessive wire loops, yet short enough to avoid unwanted slack in tight installation spaces where cable management is critical.
- Male to Female JR Connector — This extension lead features JR-standard male and female connectors, making it fully compatible with all JR-specification servos and receiver ports used in modern RC models, helicopters and other applications across the UK RC market.
- Heavy-Duty 22AWG, 60-Strand Wire — The combination of 22AWG gauge wire with 60-strand construction provides excellent current-carrying capacity and durability, ensuring reliable power delivery to your servos without voltage drop or signal degradation, even under demanding racing conditions.
- Connector Clip Included — The integrated connector clip securely holds the JR plug in place, preventing accidental disconnection during hard landings, crashes, vibration or rough handling, which is essential for maintaining consistent servo control in competitive RC racing and bashing.
- Correct Colour Orientation — The Brown/Red/Orange colour scheme matches standard JR specifications exactly, eliminating confusion during installation and reducing the risk of reversed polarity connections that could damage servos or receiver electronics.
- 1.5mm Outer Diameter — The thin 1.5mm cable diameter allows this extension lead to fit through tight cable conduits and routing channels in modern RC model designs without kinking or damage, perfect for cramped spaces in 1/10 scale and smaller vehicles.
- Lightweight Design — Weighing just 0.01kg, this extension lead adds negligible weight to your RC model while providing essential wiring functionality, maintaining the performance characteristics of your carefully balanced chassis.
Technical Performance
The Radient JR Twisted HD Extension Lead represents high-quality engineering designed specifically for the demands of modern RC hobby applications. The 22AWG wire gauge with 60 strands provides an optimal balance between flexibility and current capacity, allowing reliable power delivery to servo motors without the voltage sag that occurs with thinner, lower-strand-count alternatives. The twisted HD construction refers to the tight helical twist of the conductors, which reduces electrical noise and electromagnetic interference—a critical consideration when running modern digital servos alongside brushless ESC systems in competitive RC cars. The 1.5mm outer diameter fits comfortably in tight spaces within RC model chassis, particularly in 1/10 scale buggies, trucks and rock crawlers where space efficiency is paramount. The connector clip is manufactured to precise tolerances to ensure a secure, vibration-resistant connection without requiring excessive force that might damage delicate JR servo connectors over repeated use. Whether you're running micro servos in a compact 1/12 scale vehicle or standard-sized servos in a larger RC truck, this extension lead's specifications make it suitable across the entire range of hobby-grade RC models available in the UK.

Frequently Asked Questions
- What is a JR servo extension lead and why do I need one for my RC model? — A JR servo extension lead allows you to move your servo further away from the receiver, enabling cleaner cable routing and better weight distribution inside your RC car. Instead of running long cables directly from the receiver, you can use multiple shorter extensions to neatly route servo connections around the chassis, improving both organisation and cable management. This is particularly useful in competitive RC racing where every millimetre of internal space counts and cable routing affects weight balance.
- Will this extension lead work with my RC car or truck? — Yes, this extension lead is compatible with any RC model that uses standard JR-specification servo connectors, which includes the vast majority of modern RC cars, trucks, buggies, crawlers and helicopters available in the UK market. If your model uses JR connectors (as opposed to Futaba, Spektrum or other alternatives), this lead will connect directly to your receiver servo ports and servo plugs.
- What does the connector clip do and why is it important? — The included connector clip secures the JR plug to the receiver port, preventing accidental disconnection due to vibration, impacts or rough handling. In competitive RC racing and bashing, unwanted servo disconnection can cause loss of control or servo feedback issues. The clip keeps your connection rock-solid, which is essential for reliable servo operation during high-speed driving or aggressive manoeuvres.
- Is 100mm the right length for my application? — The 100mm length is ideal for routing servo connections a moderate distance from the receiver without excess cable bulk. If you need shorter connections, consider 50mm leads; if you need longer runs, 200mm or 300mm extensions are available. The 100mm option represents the most popular choice for general-purpose RC applications in the UK hobby market.
- Can I use this extension lead with any servo type? — Yes, this lead is compatible with all servo types that feature standard JR male connectors, including analogue servos, digital servos, micro servos and full-size servos. The 22AWG wire capacity is suitable for servos drawing typical current loads in standard RC models.
- Is this product suitable for beginners? — Absolutely. This extension lead is straightforward to install and requires no tools or soldering. Simply plug it into your receiver's servo port, connect your servo to the opposite end, and use the connector clip to secure it. The correct colour orientation (Brown/Red/Orange) prevents installation mistakes, making it beginner-friendly. The age recommendation of 14+ reflects general RC hobby guidelines.
- What's the difference between the Radient JR Twisted HD and other extension leads? — The Radient JR Twisted HD features heavy-duty 22AWG, 60-strand wire construction with a twisted design that reduces electrical noise, compared to standard extension leads that may use thinner wire or fewer strands. The included connector clip is a premium feature that keeps connections secure, and the HD (heavy-duty) designation indicates this lead is engineered for demanding applications rather than light-duty hobby use. This makes it an excellent choice for competitive RC racing in the UK.
