ESC:
Built-in polarity protection. The XR10 Justock has integrated MOSFET's 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 Wireless 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 this 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
ESC includes the Freewheeling setting allowing for lower ESC temps enhancing drivability through corners
Built-in data logging for post-run reports
Motor:
Use of a heat-resistant magnet attached aluminum case and double insulated windings, high precision bearings, and rotor with a strong structure guarantees outstanding performance and super durability
Built-in Hall sensor non-adjustable end bell combined with a high precision and balanced rotor guarantees the user a smooth and linear power on demand
Silicon O-ring seal fitted between the end bell and stator helps to 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
This Justock motor is applicable to various 1/10th, 1/12th on-road & off-road vehicles. It can be an ideal choice for Stock or Sport class races but can also be a nice choice for newbies for practice
The motor design is in compliance with IFMAR, and ROAR specifications
