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. Package includes motor, sensor wire and bullet connectors.

  • Linear & Smooth Control: The built in hall sensor and non adjustable end bell, combined with a precision, balanced rotor provides smooth and linear power.
  • Dustproof & 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 & Play: Built in 3.5mm low impedance bullet connectors provide a stable, low resistance connection.
  • 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.

Hobbywing XERUN Justock 3650 Sensored Brushless Motor (17.5T)
I own many motors and am only leaving a review so other buyers know what they are getting.
This motor is cheap and runs just fine for its price. If you don't race, it could be a good option for kids or adults with a 2wd driving around the yard. Since I do race, the rest of my review will come from that prospective.

This motor is slow compared to other 17.5t motors I own due to not having timing. The ESC that comes with this motor when purchases together is very good and I still use in races and so do many other racers. This is a motor that should be a "hand-out" motor meaning if you really want to see who the best driver is and not who is the best driver combined with the most money, this should be it. Every tested motor has a KV of between 2,200 and 2,400 which is fine. If you want a motor that will keep up in a race with end-bell timing allowed which most do, this is not it. If you drive a perfect race, you will still get lapped where I race at. If you don't know about 17.5t stock racing, it was meant for beginners because it was fairly cheap, much slower and controlled. I now race with a guy who has a motor that he has over $400 in.(ceramic barring, stators, testing for basically 6amps, etc.) The stock class is now a money pit. Buy a 8.5t or 7.5t and race modified.

NOTE: I own many products such as Tekin, HW, Trinity, Reedy, Orion, etc. and HW hangs right with the best regarding ESC's and other motors.)
