Introducing the Hobbywing Justock xR10 G3 brushless speed control.

Built-in polarity protection

One danger that all electrical systems face is a reversed polarity from the power source. This can be caused by a short circuit, or usually, incidentally reversing the terminals. The xR10 Justock is integrated using MOSFET. If the battery terminals are connected in reverse, the MOSFET will be reverse-biased and will not allow current to flow through the system.

Built-in capacitor module

The built-in capacitor module eliminates the need for external capacitors and unwanted space.

RPM speed limit function

The ESC is able to support up to 6 different speed (RPM) selections to meet the needs and demands of various competitions in the world. It can be programmed through using the latest OTA Bluetooth module or the traditional 3in1 program box.

Zero timing competition design

The internal timing of the ESC is fixed at 0 degrees and cannot be adjusted. It is specifically built for zero timing races around the world.

Built-in BEC supporting high-voltage steering gear

The ESC has a built-in BEC which can support a maximum output current of up to 8A and the output voltage at either 6V or 7.4V. This will ensure constant power supplied to today’s high-torque servos in the market.

User-friendly and convenient for set-up

The ease of having a dedicated programming port eliminates the trouble of plugging and unplugging the cable to the receiver. In addition, the interface can power additional fans to further dissipate heat. The user-friendly interface allows for easy and convenient setup by simply connecting the 3in1 LCD programming box or OTA Bluetooth module to the dedicated programming port.

Protection functions

The various protection functions have greatly improved the reliability and durability of the ESC.

Single programming and RESET design button

The ESC is designed with a single built-in SET button. Calibrating or doing a factory-reset can be achieved by using this SET button. Simple and easy to use.

Support bi-directional motor movement

The ESC supports both CCW (counterclockwise) and CW (clockwise) motor rotational directions for different usage on the market.

Support ESC firmware upgrade

Hobbywing engineers are constantly innovating and pushing the limits of its products. Enjoy the latest functions by upgrading to the latest firmware. Simply connect the ESC using either the HW LINK App via the OTA Bluetooth module or the USB LINK software through the computer.
