the hobbywing xerun justock zero spec sensored brushless esc/motor combo was developed for zero-timing spec racing. The esc timing has been permanently set to 0 °, to ensure 100% fair and competitive racing when racing in spec motor classes.

hobbywing's xerun justock 3650 sensored brushless motors are a great low cost option for stock class club racing. Featuring a heat resistant magnet attached steel case, double insulated windings, precision bearings, fixed endbell and a heavy duty balanced rotor, the justock 3650 delivers outstanding performance and durability that makes them an excellent club handout motor for spec series racing, as well as a practice motor.  

features: 

• esc:
  • high reliability and; durability: reliable hardware with advanced software allows the xr10 justock to provide high power outpu.
  • efficient heat dissipation: the modified heat sink provides increased surface area. This, combined with hobbywing's patented copper heat conductive plates, allows heat to be quickly transferred to the heatsink for dissipation. The added high performance fan creates a reliable heat management system for maximum cooling.
  • small footprint: the small, compact size allows the xr10 justock to fit most 1/10 touring car, 1/12 pan and f1 applications.
  • many applications: the esc was designed for 1/10 touring car, 1/12 pan and f1 applications, but is an excellent choice for any spec racing class. Plus, when paired with a 32t or similar motor, it is an ideal low cost choice for rock crawler applications.
  • single button programming and; factory reset: the set button on the esc allows the user to easily program or reset the esc to default mode.
  • regular firmware updates: upgrade the xr10 justock with the hobbywing usb link software, multifunction lcd program box and a pc. Hobbywing updates the esc firmware regularly, giving you access to upgraded features on a consistent basis.
• motor:
  • linear and; smooth control: the built in hall sensor and non adjustable end bell, combined with a precision, balanced rotor provides smooth and linear power.
  • dustproof and; heat conductive silicone o-ring seal: the o-ring installed between the end bell and stator helps to conduct inner heat to the motor case, and also prevents dust from entering the hall sensor.
  • plug and; play: built in 3. 5mm low impedance bullet connectors provide a stable, low resistance connection and allow easy motor removal without a soldering iron.
  • re-buildable design: the end bell can be easily removed for routine maintenance and for replacement of common wear parts, such as the rotor, bearings and sensor module.
  • compatibility: this motor is compatible with all esc's, but is a perfect match for the xr10 justock esc and all other hobbywing esc's. It is a great choice for stock or sport classes, but is a great choice for beginners or racers looking for a practice motor.
  • ifmar/roar compliant: motor is designed within ifmar/roar specifications.
