Key Features

• 400mm Total Length — The 400mm measurement includes the connectors, giving you a generous working length that provides flexibility in servo placement whilst maintaining clean cable routing in your RC model.
• Male to Female Futaba Connector Configuration — This extension lead features standard Futaba connectors (in black, white and red wire colours) that are universally compatible with Futaba-style receivers and servos, ensuring broad compatibility across most RC systems.
• Heavy-Duty Construction — Built with professional-grade materials and engineering, this extension lead is designed to withstand the demands of serious RC use, from racing applications to bashing and crawling.
• 60-Strand Wire Construction — The 60-strand design provides excellent flexibility and durability, allowing the cable to bend and route cleanly without kinking whilst maintaining consistent signal and power delivery across its length.
• 22AWG Wire Gauge — This wire gauge specification ensures sufficient capacity for robust power and signal delivery to your servos, supporting the electrical demands of modern servo systems without voltage drop.
• Connector Clip Included — The supplied connector clip securely holds the male and female connectors together during use, preventing disconnection from vibration or accidental separation and ensuring reliable operation in demanding RC conditions.
• 1.5mm Outer Diameter — The compact 1.5mm outer diameter (2mm overall with insulation) allows easy routing through tight spaces within your RC model whilst maintaining the structural integrity needed for reliable operation.

Technical Performance

The Radient Futaba HD Extension Lead represents a thoughtfully engineered solution for RC builders who understand that quality connectors and wiring are fundamental to reliable servo operation. The 60-strand wire construction strikes an optimal balance between flexibility and durability—essential when routing cables through tight compartments in RC cars, trucks, and buggies. The 22AWG wire gauge has been specifically selected to handle typical servo current demands without introducing signal noise or voltage drop, which would compromise servo response and accuracy. The 1.5mm outer diameter keeps the overall package compact, making this lead ideal for tightly packaged RC models where space is at a premium. The professional-grade Futaba connectors are engineered to military standards, providing the kind of contact pressure and retention that serious RC competitors rely upon. The included connector clip is a practical addition that demonstrates real-world understanding of servo wiring challenges—vibration and movement can cause even good connectors to separate slightly, and this clip prevents that occurrence. Whether you're working on a precision 1/10 touring car, a capable 1/8 off-road buggy, or a full-scale 1/6 crawler, this extension lead provides the performance foundation you need for reliable servo connectivity. The build quality is comparable to original equipment manufacturer standards, making this an economical choice for builders who refuse to compromise on critical components.

Frequently Asked Questions

• Is this Futaba extension lead suitable for all RC servo systems? — This extension lead features standard Futaba connectors (black, white and red configuration) and is compatible with any RC receiver or servo system using Futaba-style connectors. This includes a vast majority of modern RC systems, particularly those from Futaba, Spektrum, and many other manufacturers. Always verify that your specific receiver and servo use Futaba connectors before purchasing.
• What does the connector clip do and why should I use it? — The included connector clip secures the male and female connectors together, preventing accidental disconnection caused by vibration, impact, or normal movement during RC operation. This is particularly important during racing or bashing, where repeated impacts could otherwise loosen standard push-fit connectors over time.
• Can I use this extension lead in waterproof RC applications? — Whilst the extension lead itself is built to high standards, the Futaba connectors are not fully sealed and should not be submerged or exposed to heavy water spray. For waterproof applications, you would need to use sealed connectors and careful cable sealing practices.
• Is the 22AWG wire gauge sufficient for my servo application? — The 22AWG wire gauge is designed for standard servo applications typical of 1/10, 1/8 and smaller scale RC models. For high-current servo systems (such as large-format rock crawlers with multiple high-torque servos), you may want to consider heavier gauge wiring, but for most RC applications, this lead provides excellent performance.
• What is the actual working length of this 400mm extension lead? — The 400mm measurement includes the male and female Futaba connectors on each end. The actual flexible cable length is approximately 350-360mm depending on connector configuration, providing practical flexibility for servo placement whilst maintaining clean cable routing.
• Can I solder or modify this extension lead? — This extension lead features standard Futaba connectors that can be disconnected if needed, but soldering or modifying the connector pins is not recommended as it may damage the precision-engineered connector contacts. If you need a custom solution, consider having an experienced RC technician assist you.
