Heritage Handling: XRAY 309960 Featuring the Hobbywing XRS Justock G2 21.5T Motor

Enthusiasts restoring classic RC cars or assembling a period-correct rig will value the XRAY 309960 paired with the Hobbywing XRS Justock G2 21.5T Motor. It preserves the driving characteristics of older models while improving reliability for regular use.

Authentic Vintage Drive

The Justock G2 provides smooth, controllable power suited to vintage vehicle dynamics. Its torque profile keeps the driving feel true to older designs while allowing drivers to run consistent lap times in heats.

Consistent Output and Cooling

With a focus on thermal stability, this motor keeps output predictable across extended runs. The integrated cooling reduces the risk of thermal throttling and helps maintain consistent performance between heats.

Practical Tuning Advice

Fine-tune gearing to match track layout and pair the motor with an ESC configured for low timing and soft throttle response. These adjustments reduce current spikes and improve drivability for both display and competitive runs.

Specifications

  • Motor Type: Brushless

Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this motor fit in my original XRAY T Series car?

In most cases yes, but confirm the motor mount spacing and shaft length on your chassis. Minor adaptor plates or shims can help achieve correct mesh if needed.

How does the 21.5T turn count affect drivability?

A 21.5T motor generally offers smoother throttle response and lower peak RPM compared to lower-turn motors, which helps maintain control on vintage chassis and prolongs component life.

Should I monitor motor temperature during events?

Yes, monitoring temperature during the first runs is wise. If the motor runs hot, reduce pinion size or improve airflow to keep performance consistent and avoid damage.

Are spare parts readily available for this motor?

Basic service parts like bearings and mounting hardware are commonly available. Keep a set of spares on hand for events to minimise downtime if a part wears or fails.
