This is the kind of component that separates a professional setup from an amateur one, offering peace of mind that your servo connections will remain secure throughout your RC adventures.

Designed specifically for models using JR-style servo connectors, this extension lead features robust construction and intelligent design features that make it the preferred choice for discerning RC modellers. The 100mm length (including connectors) provides flexibility for routing cables through tight spaces whilst maintaining clean aesthetics in your RC model's interior. Whether you're setting up a tight RC crawler build, a sleek racing drone, or a complex multi-servo aircraft, this extension lead delivers the performance and reliability you need to keep your model operating at peak efficiency.

At RC Model Shop, we stock the full range of Radient heavy-duty servo leads because we know our customers demand only the best components for their RC builds. This particular extension lead represents outstanding value and is an ideal choice whether you're a beginner discovering the world of RC for the first time or a seasoned competitor looking to upgrade your existing setup with higher quality connectors and wiring.

Key Features

• 100mm Length (Including Connectors) — The compact 100mm total length makes this extension lead perfect for short servo runs where space is at a premium, allowing you to route cables neatly without excessive slack that could snag or catch during operation.
• Male to Female JR Connector Configuration — This extension lead features a male JR connector on one end and a female connector on the other, making it compatible with standard JR-style servo connectors found on virtually all modern RC servo equipment and receiver outputs across aircraft, cars, boats and helicopters.
• Heavy-Duty 22AWG, 60-Strand Wiring — The high-strand-count copper wire provides superior flexibility and durability compared to solid core alternatives, reducing the risk of wire breakage from repeated flexing whilst maintaining excellent electrical conductivity for clean signal transmission to your servo.
• Integrated Connector Clip — The included connector clip securely holds the plug in place once connected, preventing accidental disconnection during transport, operation or rough handling, which is particularly valuable in high-vibration environments like off-road RC cars and buggies.
• Professional Colour-Coded Wiring — The lead features brown, red and orange wiring using the standard JR colour scheme, ensuring compatibility and making it immediately obvious which lead is which in complex multi-servo setups, reducing installation errors and troubleshooting time.
• Compact 1.5mm Outer Diameter — The slim profile of this extension lead allows it to fit through tight cable routing channels and conduits in your RC model without creating bulk, maintaining the overall weight and balance characteristics of your build.
• 2mm Overall Diameter Specification — This precise engineering ensures consistent fit and finish across your RC setup, providing reliable mechanical connection stability that won't degrade over time with repeated use.

Technical Performance

The Radient JR HD Extension Lead with Clip 100mm represents engineering excellence in servo extension design. The 60-strand copper construction operating at 22AWG gauge provides the optimal balance between signal fidelity and mechanical strength, ensuring your servo control signals arrive at the servo with zero signal loss whilst the physical construction can withstand the vibration and flex cycles common in demanding RC applications. The heavy-duty classification means this lead can reliably handle the current demands of standard and high-torque servos without voltage drop, maintaining consistent servo response across the entire operational envelope of your RC model. Whether you're running this lead in a high-speed RC car bouncing across rough terrain, an aerobatic RC aircraft pulling hard manoeuvres, or a scale RC boat navigating choppy water, the robust construction ensures years of reliable service. The integrated connector clip is a thoughtful engineering touch that prevents the frustration of intermittent servo dropouts caused by vibration-induced disconnections, a common issue in poorly designed extension leads. The professional quality of this Radient lead is evident in every detail, from the colour-coded wiring that follows industry standards, to the precise conductor gauge that matches the performance characteristics of modern digital servo systems. At just 0.01kg in weight, this extension lead adds negligible mass to your RC model whilst providing substantial improvements in cable management and connection reliability.

Frequently Asked Questions

• What is a JR servo extension lead and why do I need one? — A JR servo extension lead allows you to extend the distance between your RC receiver and your servo, or to re-route cables for neater organisation and improved build aesthetics. This particular 100mm lead is ideal for short runs where you need to bridge a gap without excessive wiring, and the connector clip prevents disconnections caused by vibration during operation.
• Is this suitable for all RC models using JR connectors? — Yes, this extension lead is designed to work with any RC model using standard JR-style servo connectors, including RC cars, RC buggies, RC trucks, RC aircraft, RC helicopters and RC boats. If your receiver outputs and servos use brown/red/orange JR connectors, this lead will work perfectly.
• What does the 22AWG 60-strand specification mean for performance? — The 22AWG refers to the wire gauge, which determines the current-carrying capacity and signal quality. The 60-strand construction means the copper is made from 60 individual wires twisted together, providing flexibility and durability superior to solid core wire. This specification is perfectly matched to standard servo applications and provides excellent performance without excessive weight.
• Can this extension lead be used with digital high-torque servos? — Yes, absolutely. The 22AWG gauge and 60-strand construction provide sufficient current capacity for high-torque digital servos that draw more current than standard analogue servos. The heavy-duty classification specifically indicates suitability for demanding servo applications.
• Does the connector clip come attached? — Yes, the connector clip is included with the lead and is designed to hold the male connector securely in place once inserted into the female connector, preventing vibration-induced disconnection that could cause servo dropouts or loss of control during flight or operation.
• How does 100mm compare to longer extension leads? — The 100mm length (3.94 inches) including connectors is designed specifically for short runs where minimal cable routing is needed. If you require longer extensions for greater distance between receiver and servo, longer options are available, but this 100mm lead is perfect for compact, organised builds where neatness matters.
• Is this a quality upgrade over standard extension leads? — Yes, the Radient JR HD range represents a significant quality upgrade over budget extension leads, featuring the heavy-duty 60-strand construction, integrated connector clip, and professional colour coding that ensure reliable operation across thousands of flight hours or driving sessions without degradation.
