eTronix JR Twisted Servo Extension Lead 90cm 22AWG Cable ET0739J

Overview

The eTronix JR Twisted Servo Extension Lead – 90cm (900mm) is an essential accessory for RC enthusiasts who need to extend the reach between their servo and receiver. Whether you're building an RC car UK, RC truck, RC plane, or RC boat, this straightforward extension solution provides the extra length necessary for models where components are positioned further apart. The neatly twisted cable design keeps your wiring organised and tidy across chassis, wings, hulls or any other mounting area, ensuring your RC model looks professional and functions reliably.

At 90cm in length, this ET0739J extension lead is particularly well-suited to larger RC builds such as competition-grade RC buggies, scale trucks, touring cars, or high-performance RC planes and gliders that require longer servo runs. The twisted construction is not merely aesthetic – it actively helps manage cable routing and reduces the risk of tangling or interference with moving parts. If you're setting up a new RC car UK project or upgrading an existing model with additional servo channels, this extension lead offers a practical, cost-effective solution that works with any RC equipment featuring JR-style servo connectors, which remain one of the most popular standards across the hobby.

This product is designed for hobbyists of all experience levels, from weekend bashers enjoying casual RC car UK adventures to serious competitors and scale modellers who demand precision and reliability. The eTronix brand brings trusted quality and affordability to the RC community, and this extension lead is manufactured to proper standards to ensure safe, consistent operation in your RC vehicle.

Key Features

• 90cm (900mm) Extended Length — The full 90-centimetre length allows you to position your servo and receiver further apart than standard leads permit, making it ideal for larger RC models, longer fuselages in planes, or complex installation layouts in trucks and buggies where you need flexibility in component positioning.
• JR-Style Connectors — Compatible with the industry-standard JR connector format, this extension lead works seamlessly with the vast majority of RC receivers and servos available in the UK market, ensuring broad compatibility across different brands and model types without requiring adapters.
• 22AWG Twisted Wire Construction — The 22 American Wire Gauge twisted cable provides reliable power delivery to your servo whilst the twisted design keeps the wiring neat and organised, reducing the visual clutter in your RC model and minimising the risk of cable snagging on moving components.
• Neat, Practical Cable Management — The carefully twisted construction isn't just for appearance; it actively helps keep wiring organised across chassis, wings or hulls, making installation cleaner and maintenance easier, particularly in complex multi-servo setups common in RC cars, trucks and aircraft.
• Professional Build Quality — eTronix extension leads are manufactured to proper specifications, ensuring consistent polarity and secure connections that won't fail under the vibration and stress typical in RC models, from bashing to racing applications.
• Universal RC Model Compatibility — Whether you're working on RC cars, trucks, buggies, planes, gliders, boats or any other RC vehicle type, this extension lead adapts to your needs, making it an invaluable addition to any RC hobbyist's spare parts collection.

Technical Performance

The eTronix JR Twisted Servo Extension Lead ET0739J is engineered with 22AWG twisted wire, a gauge that provides sufficient current-carrying capacity for standard servo applications whilst remaining flexible and manageable in tight installation spaces. The twisted construction plays a crucial role in both safety and aesthetics – it reduces electromagnetic interference that could affect servo signal quality, helps prevent tangling with moving parts like suspension arms or control surfaces, and creates a professional appearance befitting any serious RC build. The JR-style connector format is one of the industry's most recognised standards, ensuring this extension lead will work with the overwhelming majority of receivers and servos encountered in RC cars UK, RC aircraft, boats and other hobby-grade models. The 900mm length is specifically designed for larger RC platforms and complex installations where standard short extension leads fall short, making it equally suitable for a competition-grade 1/10 scale RC buggy as it is for a large-scale RC plane or a dedicated RC touring car. Build quality is consistently reliable, with proper insulation, secure connector fitment, and conductivity that meets hobby standards, allowing worry-free operation in conditions ranging from casual backyard bashing to organised racing events.

Frequently Asked Questions

• Is the eTronix JR Twisted Servo Extension Lead compatible with my RC car UK? — Yes, if your RC car, truck, buggy or any other RC model uses JR-style servo connectors (one of the most common standards in the hobby), this extension lead will work perfectly. Always check your receiver and servo connectors before purchase to ensure JR-style compatibility; if you're unsure, contact our experienced team at RC Model Shop and we'll help you identify your connector type.
• What length extension lead do I need for my RC model? — The 90cm (900mm) length of this eTronix extension lead is ideal for larger RC models where the servo and receiver are positioned further apart than standard 30-50cm leads allow. If you're working on an RC car UK with a long chassis, a large-scale plane, a multi-servo boat setup, or any build where component distance exceeds 60cm, this 90cm option is the right choice.
• Can I use this extension lead in multiple RC models? — Absolutely. This is a universal JR-style extension lead with no model-specific electronics or programming, so you can use it across different RC cars, trucks, planes, boats and other vehicles throughout your collection, making it an excellent investment for any serious hobbyist.
• Is the 22AWG wire gauge suitable for all servo types? — Yes, 22AWG is the standard wire gauge for servo extension leads and provides ample capacity for standard RC servos across all hobby applications, whether you're running micro servos in a compact RC car UK, mid-range servos in aircraft, or larger servos in trucks and boats. For extremely high-current or large-scale applications, check your servo's specific current requirements, but standard hobby servos operate safely on 22AWG wire.
• Why is the cable twisted rather than straight? — The twisted construction serves multiple purposes: it reduces electromagnetic interference that could affect servo signal clarity, prevents the cable from tangling with moving parts like suspension arms or control surfaces, creates a neater, more professional appearance in your RC model, and makes cable routing easier during installation. It's both functional and aesthetic.
• What's the difference between JR and other servo connector styles? — JR, Futaba, Spektrum and others are different physical connector formats. The eTronix JR extension lead works with JR-format connectors; if your RC model uses Futaba S-style or other formats, you would need a different extension lead. Our RC Model Shop team can help you identify your connector type if you're unsure.
