15T Pinion — Tuning Guidance

The MG215T/0.5M 15-tooth pinion is designed for motors that accept a 0.5mm module and a 2.2mm bore, offering a compact option when adjusting gear ratios in small RC drivetrains.

Made from heat-treated 40Cr steel for improved wear resistance, the gear secures via two 3x3 set screws. Correct alignment and even torque on those screws are important to keep meshing smooth.

Tuning tips:

Measure module and motor bore before changing pinion sizes to ensure correct engagement.
Adjusting pinion tooth count alters final drive ratio and therefore motor load and performance; assess changes carefully.
Fit this as a direct swap only when the tooth count, module and bore match the current setup.

How will fitting a 15T pinion affect performance?

Changing to a different pinion tooth count alters the gear ratio, which affects acceleration and top speed and can change motor load. Monitor motor temperature and driveline behaviour after changes.

Do I need to change the spur when swapping pinions?

Consider matching the pinion change with a spur gear change to reach the desired ratio. Check mesh and clearances whenever either gear is altered.

Could gear changes affect motor temperature?

Yes. Different gear ratios change motor load; after fitting a new pinion, run short tests and monitor motor temperature to ensure safe operation.
