The Hobbywing XR10 Justock G3 Sensored Brushless ESC/SD G2.1 Motor Combo has been designed with fixed, 0°, timing for spec class racing. The included SD G2.1 motor is an ideal stock motor for both 1/10 and 1/12 on and off-road racing. These two components paired together make for an ideal choice for beginners and experts alike.

• Built-in polarity protection. The XR10 Justock has integrated MOSFETs that if the battery terminals are connected in reverse, the MOSFET will be reverse-biased and will not allow current to flow through the system
• Programmable via OTA Bluetooth module or 3in1 program box
• Built-in capacitor module eliminates the need for external capacitors and unwanted space
• RPM speed limit function supports up to 6 different speed/RPM selections to meet the needs and demands of various competitions in the world (set through OTA module or 3in1 box)
• Internal ESC timing has been set to 0 degrees and cannot be adjusted for stock racing
• Built-in BEC can support a maximum output current of up to 8A; output voltage can be set between 6V or 7.4V
• Calibration or performing a factory reset can be achieved by using the SET button — simple and easy to use
• Supports both CCW (counterclockwise) and CW (clockwise) motor directions
• Protection functions include: reverse polarity, battery voltage, ESC temperature, motor temperature, signal lost, and locked rotor protection
• Supports ESC firmware upgrades
• User-friendly and convenient for set-up
• Heat-resistant magnet-attached aluminium case, double insulated windings, high precision bearings, and strong rotor structure guarantees outstanding performance and super durability
• Built-in Hall sensor non-adjustable end bell combined with a high precision balanced rotor guarantees smooth and linear power on demand
• Silicone O-ring seal fitted between the end bell and stator helps conduct inner heat to the motor case and prevent dust from entering the Hall sensor
• Detachable structure design for daily cleaning and maintenance can effectively prolong the service life of this Justock motor and improve its operating efficiency
• Applicable to various 1/10th and 1/12th on-road Stock Spec Racing, ICC, IOCC, USVTA, TOUR, and Oval racing; an ideal choice for Stock or Sport class races, and also suitable for beginners for practice
• Motor design is in compliance with IFMAR and ROAR specifications

Notice: Brushless electric motors and ESCs have huge amounts of torque at any given RPM. Using too-tall gearing, or a vehicle that is too large or heavy, can result in damage and/or product failure. Please consult your manual and select gearing suitable for the vehicle and terrain, as damage caused by overloading or abuse is unlikely to be covered by the manufacturer's warranty. Always monitor your ESC and motor temperatures closely after modifying your system to ensure they stay within the safe operating limits.
