Frequently Asked Questions
- Is the LOGIC JR Extension Lead (Silicone) 300mm compatible with my RC radio system? — Yes, this lead is fully compatible with all JR and Spektrum type plugs, which covers the vast majority of modern RC transmitters and receivers used in RC cars UK, RC aircraft, RC helicopters, and RC boats. If your system uses JR or Spektrum connectors, this extension lead will work seamlessly with your equipment.
- What makes silicone insulation better than standard PVC leads? — Silicone insulation offers superior flexibility, allowing easier routing through tight spaces in your RC model, and maintains performance over a wider temperature range. It also resists cracking and degradation better than PVC, meaning your extension lead will last longer even with frequent bending and installation cycles.
- Will this extension lead work for extending signals to my servos in an RC aircraft? — Absolutely. The 300mm length and silicone construction make it ideal for RC aircraft installations where you need to route signals from the receiver to servos located at various points on the wing, fuselage, or tail without compromising signal quality.
- Is this suitable for beginners? — Yes, this extension lead is perfect for beginners. It features standard JR/Spektrum connectors which are industry-standard, making it simple to connect and disconnect. The gold-plated connections ensure reliable operation even with minimal experience, giving new RC enthusiasts confidence in their builds.
- What is the difference between the silicone and HD heavy-duty versions? — The silicone version features premium silicone insulation for superior flexibility and temperature resilience, making it ideal for demanding applications and tight routing scenarios. The HD (heavy-duty) version uses standard PVC insulation but still offers robust construction. Choose silicone if you need exceptional flexibility or plan to use the lead in variable temperature environments.
- Can I use this lead in both RC cars and RC aircraft? — Yes, this is a universal extension lead compatible with any RC system using JR or Spektrum connectors, whether for RC cars, aircraft, helicopters, boats, or drones. The 300mm length works well for most applications requiring moderate reach between receiver and servo.
- How durable is the gold-plated connector? — Gold plating provides excellent corrosion resistance and maintains consistent electrical contact through hundreds of connection cycles, ensuring your signal remains clean and clear throughout the lifespan of your RC model without degradation from oxidation or wear.
