Retro Drive with Modern Control: XRAY 309960 and Hobbywing XRS Justock G2 21.5T Motor

Collectors and racers who enjoy classic handling will appreciate the XRAY 309960 combined with the Hobbywing XRS Justock G2 21.5T Motor. It keeps the old-school driving dynamics while adding reliable, contemporary motor behaviour for weekend meets and display models.

Optimised for Vintage Chassis

The Justock G2 is built to match vintage XRAY platforms, offering consistent acceleration and torque that suit older gear ratios. Its steady power delivery makes it simple to set up on original T Series mounts without losing the car's period feel.

Balanced Power and Cooling

This motor offers a balanced output for controlled corner exits and steady lap pacing. The integrated cooling helps prevent heat soak, which keeps performance predictable during back-to-back heats at the track.

Practical Setup Hints

To get the best from the Justock G2, check pinion size and spur engagement and use an ESC tuned to low timing and smooth throttle curves. Those adjustments reduce current draw and improve the motor's service life.

Is this motor a good match for older T Series mounting points?

Yes, the motor integrates well with older T Series layouts, but confirm shaft length and mounting holes during installation to ensure proper alignment with your gearbox.

What gearing should I start with on a high grip track?

Start conservatively with a slightly lower pinion to avoid overheating. Test a couple of steps up until you find a balance of acceleration and temperature suitable for your surface.

Can I run this motor on brushed setups?

No, this is a brushless motor and requires a compatible brushless ESC. It is not compatible with brushed controllers or systems designed for brushed motors.

Any tips for keeping temperatures under control?

Use an ESC with thermal protection, check airflow to the motor area, and avoid overgearing on hot days. Short repeated runs with cool down periods also help maintain safe temps.
