Overview
The Hobbywing XeRun XR10 Justock G3S is a 2S sensored brushless ESC designed for 1/10th scale RC cars, with fixed 0 degree timing for zero-timing (blinky) club racing and consistent power output across identical motors.
Key Features
- Fixed timing: 0 degree
- Precise control and powerful performance for 1/10 on-road and off-road zero-timing (blinky) competitions
- Built-in polarity (reverse connection) protection
- Optimized architecture with built-in capacitor module (no external capacitor module required)
- Capacitor overheat protection function
- Protections: battery low-voltage cutoff, over temperature, fail safe (throttle signal loss protection), motor lock-up protection
- Built-in data logging and data recording support (extreme value and real-time data supported)
- Wireless data recording and analysis supported via HW Link mobile app (with compatible hardware)
- Multi RPM limit selections: adjustable from 10,000 to 88,000 RPM in 1,000 RPM increments
- Free wheeling feature (improves deceleration and controllability when throttle input is off; reduces ESC temperature when activated)
- S.M.A.R.T (Self Monitoring Analysis & Report Technology) intelligent cooling fan management system
- ESC parameter setting support via LCD program box (supported models listed in Specifications)
- Firmware upgrade supported (programming device required; sold separately)
- BEC output voltage: 6V or 7.4V; feature text states maximum output current up to 8A

Details

The XeRun XR10 Justock G3S sensored brushless ESC features a top-mounted cooling fan, clear solder posts, and a 2S LiPo marking for easy wiring.

The Hobbywing XeRun XR10 Justock G3S ESC is positioned for 1/10 on-road and off-road zero-timing (blinky) competition classes.

Built-in polarity protection helps guard the ESC against damage from accidentally reversed battery connections.

The XR10 Justock G3S ESC uses a built-in capacitor module to reduce external wiring and save space in your 1/10 RC car setup.

The XR10 Justock G3S ESC includes a built-in BEC with up to 8A output and selectable 6V or 7.4V for powering servos.

The built-in cooling fan uses S.M.A.R.T. management to help keep the ESC operating within a suitable temperature range.

Built-in data logging records key running data like voltage, maximum current, maximum RPM, and ESC/motor temperature for easier tuning.

HW Link mobile app support enables wireless real-time data recording and analysis through the OTA Programmer module.

Multiple RPM limit selections let you set the RPM limit from 10,000 to 88,000 RPM in 1,000 RPM steps.

The XR10 Justock G3S ESC includes a freewheeling feature to help reduce heat and improve deceleration control when off-throttle.
