Frequently Asked Questions
- Is the Hobbywing Xerun Switch compatible with my RC car ESC? — The switch is designed to work with Xerun 120A V2.1, Xerun 90A, Xerun 60A, Ezrun 18A, Justock, Xtreme, and QuicRun ESC models. Check your ESC model number to confirm compatibility before ordering, as this switch is a direct replacement component.
- What is the difference between waterproof and non-waterproof switch versions? — The non-waterproof version featured here is optimised for dry conditions and typical UK RC club use, including indoor carpeted tracks and outdoor on-road circuits. A waterproof version would be recommended if you regularly run your RC car in wet conditions, through water crossings, or in heavy rain at off-road tracks.
- How difficult is it to install this switch in my RC car? — Installation is straightforward for anyone with basic RC maintenance skills. The switch is a direct replacement component that integrates into your existing ESC harness, requiring only simple connector replacement. If you're unsure about installation, the team at RC Model Shop is happy to provide guidance or support.
- Will this switch work with both brushless and brushed RC motors? — Yes, this switch controls power delivery to both brushless and brushed motors through your ESC, so it works with either motor type as long as your ESC is compatible with the switch model.
- Is this suitable for beginners to RC hobbies? — This is a replacement component rather than a complete system, so it's most suitable for RC enthusiasts who already own an RC car with a compatible Hobbywing ESC. If you're new to RC and need a complete ready-to-run RC car, we recommend exploring our range of beginner-friendly models.
- What battery does this switch need? — The switch itself doesn't have battery requirements; it simply manages power delivery from your LiPo or NiMH battery pack to your Hobbywing ESC. Your choice of battery depends on your ESC and motor specifications, not the switch.
