Hobbywing Xerun Justock 3650 SD G2.1 Sensored Brushless Motor (21.5T)
About this part
The Hobbywing XERUN Justock 3650 SD G2.1 Sensored Brushless Motors feature an updated can design over the G2 - and especially G1 - and push the boundaries of an Fixed Timing Motor with lower weight, good heat dissipation and a rebuildable design.
Features:
- The 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.
- The 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.
- The 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.
- The detachable structure design for daily cleaning and maintenance can effectively prolong the service life of this Justock motor and improve its operating efficiency.
- This motor is perfectly matched with the XR10-Justock ESC for all zero timing spec racing and also compatible with other Hobbywing Electronic Speed Controllers including other brands.
- 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.

This is the motor to run if you are running a car in the 21.5T class, locked timing. Plenty of oomph - I'm happy as a 21.5T...
This is the spec motor for the majority of classes in the Tamiya Championship Series (TCS) races. They were optional for the 25 season and are a mandatory replacement for the 26 season. I have had no issues with them to date and they perform well.
Very poor quality control. Purchased 3 motors to run in spec 21.5 buggy class. Went through tech before racing and my wife's motor failed. Timing is too high. Max allowable is 46 degrees. Wife's motor is 47 degrees. Daughters motor is factory set at 42 degrees, and son's is set at 45 degrees. So a 5 degree swing straight out of the box. No wonder the speeds seem to vary! Now I have to deal with their warranty service to see if they can replace the one that I'm not allowed to race.
great motor for On road 1/10 scale. I bought few of them for my friends . Now is my turn for my Mugen MTC2
Reviewers generally rate this 21.5T sensored brushless motor highly, with buyers describing it as strong for 21.5T class racing and a standard spec motor in Tamiya Championship Series events. One reviewer reports no problems so far. A single negative review describes inconsistent timing across motors bought together, with one unit measured above the 46-degree limit and failing tech inspection, and a warranty replacement needed. Another reviewer uses the motor in on-road 1/10 scale. Overall, the reviews are few and mostly positive, with the one critical account raising a quality control concern.
- + Strong power for 21.5T class
- + Accepted as spec motor in TCS races
- + Works well in on-road 1/10 use
- − Inconsistent timing out of the box
- − Unit failed tech inspection for timing
- − Warranty replacement needed
