Etronix EC3 3.5mm Gold Connectors 1 Pair Male Female ET0601

Overview

The Etronix EC3 3.5mm Connector ET0601 is an essential accessory for RC enthusiasts who demand reliable electrical connections in their models. Whether you're building a new RC car, truck, plane, boat or drone, quality connectors are fundamental to safe, efficient operation. This 1-pair pack includes both male and female EC3 3.5mm gold connectors, making it ideal for replacing worn connectors, upgrading existing setups, or completing new builds with confidence. RC hobbyists across the UK trust Etronix connectors for their durability and consistent performance, whether you're racing competitively or enjoying casual weekend bashing.

The EC3 connector format is widely recognised as a standard connection point in the RC hobby, particularly popular for mid-range power applications across electric RC cars, buggies, trucks and aircraft. The 3.5mm gold-plated bullet connectors provide excellent electrical conductivity with minimal resistance, ensuring power reaches your motor and ESC efficiently without unnecessary voltage drop. These connectors are perfect if you're updating an existing RC car UK setup or if you're new to the hobby and want to work with quality components from the start.

Manufactured by Etronix, a trusted brand in RC electrics and accessories, this connector pack represents outstanding value for money. The gold plating resists oxidation and corrosion, extending connector lifespan and maintaining reliable performance even after frequent connect-disconnect cycles. Whether you're a seasoned RC racer, a regular basher, or discovering the world of RC for the first time, having spare quality connectors in your pit box is always sensible preparation.

Key Features

• EC3 3.5mm Gold Connectors — The connectors feature gold-plated contacts that provide superior electrical conductivity compared to standard brass or nickel-plated alternatives, reducing internal resistance and ensuring maximum power transfer to your RC model's motor and ESC components.
• Male and Female Pair — Each pack includes one male connector and one female connector, allowing you to create complete mated pairs for your battery connections, ESC leads, or device wiring without needing to purchase additional components.
• Corrosion-Resistant Design — The gold plating actively resists oxidation and corrosion that can develop on cheaper connectors over time, maintaining reliable contact integrity even in humid conditions or after extended storage between RC sessions.
• Standard EC3 Format — These connectors use the widely-adopted EC3 3.5mm standard connector format, ensuring compatibility with a huge range of ready-to-run RC models, battery packs, and electronic speed controllers across cars, trucks, planes, boats and drones.
• Compact Size — The 3.5mm bullet connector size makes these ideal for compact model builds where space is at a premium, whilst maintaining sufficient current-carrying capacity for most recreational and intermediate-level RC applications.
• Cost-Effective Solution — Priced at just £2.55 inc VAT (£2.13 ex VAT), this connector pair represents excellent value compared to purchasing replacement connectors individually or buying pre-assembled cables, making it perfect for builders on a budget.

Technical Performance

The Etronix EC3 3.5mm connectors deliver reliable electrical performance suitable for a wide range of RC applications. The 3.5mm bullet connector format, also known as EC3 connectors, is engineered to handle the power demands of typical RC car UK setups, ready to run RC trucks, and moderate-power aircraft. The gold-plated contact surfaces provide exceptional conductivity, minimising voltage drop across the connection — a critical factor when every millivolt of battery voltage is needed to maximise motor performance and runtime. The robust construction ensures the connectors maintain firm mechanical contact even after repeated mating and separation cycles, which is essential for models that are frequently packed away and transported to local RC clubs, racing events, or outdoor flying fields. These connectors work seamlessly with EC3 compatible devices and batteries, making them a universal solution for upgrading or repairing RC electrics. The 3.5mm diameter provides an excellent balance between compact size and reliable current handling, suitable for brushless RC vehicles using 2S to 3S LiPo battery packs and corresponding electronic speed controllers in the 60-120A range — the typical middle ground of recreational RC hobby equipment. Whether you're working with a brushless RC buggy, an electric truck setup, or a park flyer aircraft, these connectors maintain the electrical integrity your model deserves.

Frequently Asked Questions

• Are these connectors compatible with my RC car or drone? — The EC3 3.5mm connector is a widely-adopted standard format in the RC hobby. Check whether your battery pack and electronic speed controller both use EC3 connectors — if they do, these Etronix connectors will mate perfectly. If your model uses XT60, XT90, Deans, or other connector formats, you would need different connectors. Many ready to run RC models from various manufacturers use EC3 connections, particularly in the mid-power range suitable for recreational flying and driving.
• What is the difference between EC3 and other RC connectors like XT60 or Deans? — The EC3 is a 3.5mm bullet connector format, whilst XT60 connectors are larger (approximately 5mm) and better suited to higher-power setups, and Deans connectors (T-plugs) use a different connection mechanism entirely. EC3 connectors are ideal for moderate power applications, typically 2S-3S LiPo battery systems, while XT60 and XT90 connectors handle higher currents in 4S and above setups. Choose the connector format that matches your existing battery and ESC equipment.
• Can I solder these connectors or do I need crimping tools? — These bullet connectors can be either soldered or crimped onto silicone wire, depending on your preferred assembly method and available tools. Many RC builders prefer soldering for reliability, ensuring a solid electrical bond, whilst others use dedicated crimping tools for a cleaner finish. Ensure proper heatshrink insulation over the final connection to prevent short circuits and maintain safety.
• Why should I choose gold-plated connectors over standard brass? — Gold plating provides several advantages: superior electrical conductivity, resistance to corrosion and oxidation even after months of storage, and more reliable contact integrity through repeated connection cycles. Whilst gold-plated connectors cost slightly more initially, they deliver better long-term reliability and require less maintenance than cheaper alternatives, making them a worthwhile investment for anyone serious about their RC hobby.
• Are these suitable for high-power setups? — The EC3 3.5mm format is best suited to moderate power applications, typically supporting current flows up to approximately 60-120A depending on wire gauge and connection quality. For high-power setups using 4S, 6S, or 8S LiPo batteries with large-capacity packs and high-discharge-rate cells, you should consider larger connector formats such as XT90, XT120, or MT60 connectors which are specifically engineered for heavy continuous current draw.
