eTronix JR Twisted Servo Extension Lead 45cm 22AWG ET0736J

Overview

The eTronix JR Twisted Servo Extension Lead (ET0736J) is an essential accessory for RC enthusiasts across the UK who need to extend the reach between their receiver and servo or auxiliary device. Whether you're building a high-performance RC car, setting up a precision RC boat, or configuring a scale RC aircraft, this 45cm extension lead provides the flexibility to position your servos exactly where you need them without compromising on connector reliability. With a twisted cable design that minimises interference and maintains signal integrity, this extension lead is the perfect solution for custom RC setups where standard servo lead lengths simply don't reach.

This JR-style servo extension lead is compatible with a vast range of RC equipment used across cars, boats, aeroplanes and helicopters throughout the UK and beyond. The 22AWG wire gauge ensures robust power delivery whilst maintaining flexibility for installation in tight spaces. At just £1.99, it represents outstanding value for money and is an absolute must-have for any serious RC modeller's parts box. Whether you're a weekend basher, a dedicated racer, or a scale modelling enthusiast, having quality extension leads on hand means you can adapt your setup quickly and efficiently without investing in entirely new servo harnesses.

RC Model Shop stocks this eTronix accessory because we understand that successful RC builds depend on having the right components at hand. The JR connector standard is one of the most widely used in the hobby, found on everything from budget-friendly entry-level RC cars to high-end competition vehicles. This extension lead is the ideal complement to your existing RC fleet, whether you're upgrading an older RC car UK model or experimenting with new servo placement on a recent purchase.

Key Features

• 45cm (450mm) Length — This extended reach is perfect for installations where your receiver is mounted centrally but your servo needs to be positioned elsewhere in the chassis, giving you maximum flexibility in your RC car, boat or aircraft layout without the need for expensive custom harnesses.
• 22AWG Wire Gauge — The 22AWG specification provides an ideal balance between power delivery capacity and cable flexibility, ensuring your servos receive clean, reliable signals whilst remaining easy to route through tight RC model chassis spaces.
• JR-Style Connector — Fully compatible with the industry-standard JR servo plug format, which is found on receivers and servos across countless RC cars, boats, aeroplanes and helicopters, making this lead universally useful across your entire RC collection.
• Twisted Cable Design — The twisted construction of the cable helps to shield the signal lines and minimise electromagnetic interference, ensuring that your servo receives clear control signals without dropouts or glitches that could affect handling precision.
• Reliable Signal Integrity — By maintaining proper cable geometry and construction, this extension lead preserves the quality of servo control signals over its full 45cm length, critical for RC cars that demand precise steering and throttle response.
• Compact and Lightweight — The extension lead adds minimal weight to your RC model whilst taking up very little space, important considerations for performance-focused RC enthusiasts who carefully manage their model's weight distribution and centre of gravity.
• Ready to Use Out of the Box — Simply plug and play connection between your receiver and servo or other JR-compatible devices, with no soldering or additional preparation required before use.

Technical Performance

The eTronix JR Twisted Servo Extension Lead ET0736J is engineered to deliver reliable servo control over extended distances without signal degradation. The 22AWG wire gauge is specifically chosen to handle the current demands of standard RC servos whilst maintaining the flexibility needed for installation in modern RC chassis designs. The twisted cable construction is a professional engineering solution that reduces electromagnetic noise interference — a critical consideration in the increasingly crowded radio frequency environment where multiple RC models operate in proximity to one another. The JR connector format is one of the most robust and widely-adopted standards in the RC hobby, with secure mechanical engagement that ensures your servo connection remains stable during the vibrations and movements inherent in RC car racing, RC boating, and RC flight. The 45cm length bridges the gap between typical receiver positions (often mounted centrally in the fuselage or chassis) and servo mounting locations that might be positioned at the extremities of your RC model. Whether you're building a precision crawler with servos mounted in the differential housings, a race-spec RC car with custom servo placement, or an RC aircraft where servo runs need to reach from fuselage to wing surfaces, this extension lead provides the reach you need without compromising on signal quality or reliability.

Frequently Asked Questions

• Is this JR extension lead compatible with my RC car UK setup? — Yes, if your RC car uses JR-style servo connectors on its receiver and servos, this extension lead will work perfectly. JR connectors are found on the vast majority of RC cars, boats, and aircraft sold in the UK. However, some older or specialist RC models may use different connector standards such as Futaba or Spektrum, so please check your equipment's connector type before purchasing.
• What is the difference between a twisted extension lead and a regular one? — The twisted cable design actively shields the signal lines from electromagnetic interference, which is increasingly important in busy RC environments where multiple radio systems operate simultaneously. A twisted construction is particularly valuable if you experience servo jitter, glitches, or unpredictable behaviour when other RC models are operating nearby.
• Can I use this extension lead on any RC model? — This extension lead is suitable for general RC use across cars, boats, and aircraft, provided they use JR-style servo connectors. The 45cm length makes it particularly useful for larger RC models or installations where the receiver and servo are positioned far apart. Always verify your equipment uses JR connectors before connecting.
• Is this suitable for beginners? — Absolutely. This is one of the simplest RC accessories to install — it requires no soldering, no configuration, and no technical knowledge. Simply plug one end into your receiver's servo channel and the other into your servo. Beginners building their first RC car or upgrading an existing model will find this extension lead straightforward and reliable.
• What if my servo connector doesn't match? — If your RC equipment uses Futaba, Spektrum, or another connector standard instead of JR, this lead will not be compatible. Always check your receiver and servo connector types before purchase. Using incompatible connectors can damage your equipment, so verification is essential.
• How do I know if I need a 45cm extension lead? — Measure the distance between your receiver's servo port and where you need your servo mounted. If standard servo leads (typically 30-35cm) don't reach comfortably, then a 45cm extension is the solution. Many RC cars benefit from extended servo leads when custom mounting locations are used or when multiple servos need different reach distances.
