Key Features

• 300mm Heavy-Duty Construction — The extended 300mm length provides excellent reach between your receiver and servo or other compatible devices, allowing flexible system layouts without compromising on signal strength or adding unnecessary bulk to your setup.
• Gold-Plated Connections — Gold plating on all contact points dramatically improves conductivity and reduces resistance in the signal path, ensuring that your receiver delivers crystal-clear, interference-free commands to your servos and speed controllers with zero signal degradation.
• High-Quality Mouldings — Premium quality plastic mouldings at both ends of the lead protect the internal connections and create a robust, durable product that withstands the vibrations, temperature changes and mechanical stress of serious RC use.
• Superior Wire Quality — The internal wiring uses high-specification materials that maintain signal integrity over the full 300mm length, preventing voltage drop and ensuring consistent performance whether you're flying, driving or boating.
• JR/Spektrum Type Compatibility — Works seamlessly with all JR and Spektrum type plugs, making it the perfect universal solution for anyone running these popular radio systems across multiple RC vehicles.
• Low-Resistance Design — Every element of this lead has been engineered to minimise resistance in the signal path, translating to faster response times, more accurate servo positioning, and improved overall system responsiveness.

Technical Performance

The LOGIC JR Extension Lead (HD) 300mm represents a significant step up from standard extension leads, thanks to its heavy-duty specification and professional-grade components. The gold-plated connectors are not merely cosmetic—they provide measurably better conductivity than standard brass connectors, which is particularly important when running multiple servos or high-current speed controllers through your receiver system. The high-quality mouldings are engineered to precise tolerances, ensuring a snug, secure fit with JR and Spektrum type plugs that won't loosen under vibration or repeated connection cycles. At 300mm in length, this lead is long enough to route cables away from moving components, heat sources and potential interference points, yet short enough that you won't suffer from significant voltage drop or signal degradation. Whether you're running a brushless RC car with a digital servo and programmable ESC, an electric RC plane with multiple digital servos, or any other Spektrum or JR equipped RC vehicle, this lead will maintain the integrity of your radio signal and keep your system responding precisely to your inputs. The construction quality means this is not a disposable item—many RC modellers report using the same heavy-duty extension leads for years across multiple vehicles and applications.

Frequently Asked Questions

• Is this extension lead compatible with my Spektrum DX6 or DX9 radio system? — Yes, absolutely. The LOGIC JR Extension Lead (HD) 300mm is specifically designed for JR and Spektrum type plugs, which are standard across the Spektrum range including the DX6, DX9, DX12, and all other Spektrum transmitters and receivers. It works with any receiver using JR-standard connectors.
• Will using a 300mm extension lead reduce my servo response speed? — No, the heavy-duty construction and gold-plated connectors of this lead are specifically engineered to minimise resistance and prevent signal degradation. You will not experience any noticeable reduction in servo response speed or accuracy compared to a shorter lead.
• Can I use this lead for multiple servos? — This is a single extension lead suitable for connecting one servo or device to your receiver. If you need to connect multiple servos to a single receiver channel, you would need a Y-harness or separate extension leads for each servo.
• What is the difference between this and the silicone version? — The LOGIC range includes both heavy-duty (HD) versions and silicone versions. This HD model offers excellent durability and value for general use and competition. The silicone versions provide additional flexibility and are sometimes preferred in extreme temperature conditions or applications requiring exceptional vibration resistance. Both use the same high-quality gold-plated connectors.
• How does the 300mm length compare to other extension leads? — LOGIC RC produces extension leads in multiple lengths: 100mm for very tight spaces, 200mm for compact layouts, 300mm (this model) for flexible routing with good signal integrity, 500mm, 600mm, 750mm and 1000mm for large-scale models or applications requiring maximum cable reach. The 300mm is the most popular size for general RC car and plane use.
• Is this suitable for beginners? — Yes, absolutely. Extension leads are essential components for any RC system, beginner or advanced. This lead is straightforward to use—simply plug one end into your receiver and the other into your servo or speed controller. No technical knowledge required, and the robust construction means it will withstand beginner mishaps and learning curves.
• Will this work with my JR radio from twenty years ago? — Yes. JR-type connectors have remained largely standardised for decades, and this lead is fully compatible with older and newer JR radio systems alike. This makes it an excellent long-term investment for your RC hobby.
