Frequently Asked Questions

• What are 4.0mm male gold connectors used for in RC models? — These connectors are used to create reliable power and signal connections between batteries, ESCs, and other electrical components in RC cars, boats, and aircraft. The male connector inserts into a female connector, and the gold finish ensures low-resistance, consistent contact that prevents voltage drop and connection issues during operation.
• Can I use these connectors on any RC model? — These 4.0mm male connectors are compatible with any RC application that uses standard 4.0mm female connectors. This includes typical RC cars, boats, and aircraft. However, you should verify that your model uses 4.0mm connectors before purchasing, as some models may use different connector sizes such as 3.5mm, 5.5mm, or other specifications.
• How do I use these connectors to make custom leads? — Simply solder or crimp the male connector to the positive wire of your custom lead cable. The connector is then inserted into a corresponding 4.0mm female connector on your battery, ESC, or other component. For best results, ensure your soldering or crimping is secure and that the connector is fully seated in its mating female receptacle.
• What makes gold-finish connectors better than standard connectors? — Gold is chosen as a contact surface because it has superior conductivity and resists oxidation far better than standard plated finishes or bare metal. This means gold connectors maintain lower contact resistance over time, preventing the increased voltage drop and heat generation that can occur with oxidised or corroded connectors, ultimately protecting your RC model's electronics.
• Are these suitable for high-power RC applications? — The 4.0mm connector size is a standard specification used across numerous RC applications. However, connector suitability depends on your specific current requirements and the gauge of wire you're using. For very high-current applications, you may want to verify that your chosen wire gauge and connector combination are rated for your model's power draw.
• How many connectors do I need? — This pack contains two connectors, which is sufficient for one complete connection between two components, or you can keep one as a spare. Many RC builders maintain multiple spare connectors in their workshop to ensure they always have replacements available when connectors wear out or need refreshing.
