Technical Performance
The Hobbywing 1/10th Switch (Waterproof) for XR10 PRO DR operates as part of the complete XeRun XR10 Pro Legacy system, which is purpose-built for 1/10th scale on-road and off-road racing in both Modified and Stock classes. The XR10 Pro Legacy ESC that this switch complements delivers continuous current handling up to 150A with peak bursts reaching 1000A, providing plenty of power headroom for demanding brushless motors. The integrated BEC (Battery Elimination Circuit) supports high-voltage servos with adjustable output from 5.0 to 7.4V in 0.1V increments, delivering up to 10A of current for high-torque servo applications. The ESC accepts 2S LiPo battery input and features a powerful 32-bit M4 processor that handles complex calculations and data logging with exceptional speed and accuracy. The switch itself is engineered to withstand the demanding conditions of competitive RC racing, with waterproof sealing ensuring protection against moisture, dust, and environmental contaminants. When paired with the XR10 Pro platform, the system supports real-time data logging of throttle position, battery voltage, temperature, RPM and other critical power system parameters, accessible through the optional OTA Bluetooth module. The intelligent fan circuitry runs only when thermal management is needed, extending fan lifespan and improving overall system efficiency. Size dimensions for the XR10 Pro ESC are 37.7mm × 37.0mm × 33.2mm, weighing 94.2g including wires and connectors, whilst the switch maintains a compact profile suitable for tight chassis installations common in 1/10th touring cars, buggies, and drift vehicles popular throughout the UK RC community.

Frequently Asked Questions
- Is the Hobbywing 1/10th Waterproof Switch compatible with my XR10 Pro ESC? — Yes, this switch is specifically designed for the XeRun XR10 Pro Legacy and XR10 Pro DR platforms. The XR10 Pro Legacy ESC features a 32-bit M4 processor, 150A continuous current rating, and adjustable BEC output from 5.0 to 7.4V, making it perfect for 1/10th scale on-road touring cars, off-road buggies, and drift vehicles used throughout UK RC racing.
- Will this switch work in wet conditions or on muddy tracks? — Absolutely. The waterproof design is specifically engineered to protect against water ingress and dust contamination, allowing you to race confidently in wet weather, on muddy off-road courses, or near water features without risking electronic damage or corrosion to your power system components.
- What makes this switch better than a standard switch? — Hobbywing's waterproof switch combines precision engineering with environmental protection, ensuring reliable switching action even in demanding conditions. The sealing protects against moisture and dust whilst the compact design minimises weight impact on your 1/10th scale chassis, critical for competitive racing where every gram matters.
- Can I use wireless tuning with this switch? — Yes, the switch works with the optional OTA Bluetooth module (Model 30850400), allowing you to wirelessly connect to the HW Link mobile app on your smartphone. This enables real-time parameter adjustment, data logging with throttle and RPM monitoring, temperature tracking, and even firmware upgrades without needing to connect to a computer or LCD program box.
- What battery does the XR10 Pro system need? — The XeRun XR10 Pro Legacy ESC accepts 2S LiPo batteries (7.4V nominal), delivering 150A continuous current and 1000A peak current for high-performance racing. The BEC output provides 5A maximum current for servo operation, supporting high-voltage servo demands with adjustable output from 5.0 to 7.4V.
- Is this suitable for beginners? — While the XR10 Pro platform is competition-grade equipment designed for serious racers, the switch itself is straightforward to install and operates reliably without requiring extensive tuning knowledge. However, the full feature set—including advanced fan control, softening functions for track condition adjustment, and real-time data logging—is best appreciated by experienced racers seeking to optimise lap times and diagnose power system performance.
- What is the effective range for wireless connectivity? — The OTA Bluetooth module (sold separately) provides an effective wireless range of approximately 5 metres in open field conditions, allowing you to adjust parameters and monitor data during testing and practice sessions. Bluetooth version 4.0 or higher is required on your smartphone for compatibility with the HW Link mobile app.
- How does the intelligent fan control work? — The XR10 Pro Legacy includes Smart Fan technology that automatically activates cooling only when thermal management is needed based on real-time temperature monitoring. This temperature-controlled approach prolongs fan lifespan, reduces unnecessary power draw, and improves overall system efficiency compared to fans that run continuously regardless of thermal demand.
