HOBBYWING Xerun XR10 Justock G3S ESC – Precision 1/10 Racing Controller

Precision you can feel in every turn

The XR10 Justock G3S ESC from HOBBYWING blends exact throttle response with robust hardware for 1/10 scale racing. With fixed 0° timing, the power system remains consistent when paired with the same motor across runs, helping drivers approach each race with dependable control on a variety of track surfaces.

All-in-one design for clean, simple installs

• Built-in capacitor module eliminates the need for external parts, reducing layout clutter and streamlining mounting.
• Integrated BEC delivers steady power to high-torque servos (up to 8A at 6V or 7.4V), supporting modern servo demands.
• Reverse-polarity protection guards against accidental battery misconnection, enhancing reliability.

For data-driven tuning, the ESC can connect to an OTA Bluetooth module and the HW Link app to capture real-time performance data such as throttle input, voltage, current, temperature, and speed, enabling informed adjustments without extra gear.

• Real-time data logging and analysis help you understand how the system behaves under different conditions.
• OTA data recording stores session data for post-practice review and refinement of settings.

Flexible tuning for diverse race rules

Choose from up to 79 RPM limit settings, ranging from 10,000 to 88,000 RPM, to meet the demands of different events. Parameter tuning is accessible via the LCD program box pro or the OTA module, making it straightforward to tailor throttle response for various tracks and classes.

Protection, reliability, and easy maintenance

Multiple safeguards include battery low-voltage cutoff, over-temperature protection, fail-safe (throttle signal loss), and motor lock-up protection. A built-in capacitor overheating protection helps prevent capacitor damage during demanding sessions.

Compatibility and physical specs

Designed for LiPo 2S packs and both sensorless and sensored brushless motors, the XR10 Justock G3S features a built-in BEC (6V/7.4V) and a compact footprint (40.9 × 33.9 × 32.1 mm) with an approximate weight of 75.4 g, including wiring. A cooling fan is built into the ESC for improved thermal management, and firmware upgrades are available for ongoing improvements.

Optional interfaces include the multi-function LCD program box pro and OTA programmer for tune-ups and data features, plus the ability to view real-time data. This makes the XR10 Justock G3S a versatile choice for racers who value control and reliability without adding extra hardware clutter.
