Pinion Upgrade for MTX-5

This Arrowmax 18-tooth motor pinion is presented as a replacement/upgrade for the Mugen MTX-5 platform and is manufactured from 7075 hard aluminium. It directly engages the motor output to change gear ratio, which affects launch behaviour, maximum velocity and the electrical load on the drive components.

Fitment is aimed at MTX-5 builds; when fitting this pinion check the spur mesh carefully, confirm motor shaft diameter and keying, and adjust backlash to the chassis maker's recommended settings. Use suitable thread locking or the correct retention method typical in RC maintenance to keep the pinion secure on the motor shaft.

Tuning advice: an 18T pinion generally increases top speed relative to smaller tooth counts while raising motor and ESC load. Balance your choice of pinion with motor timing, ESC programming and battery selection to tune for quicker acceleration or higher sustained speed as required.

It is specified for MTX-5 pinion shafts; other models may share the same shaft size but always confirm shaft diameter and key alignment before fitting to avoid incompatibility.
Because an 18T increases drivetrain load, you may need to review ESC settings, cooling and battery selection to keep temperatures and current draw within safe limits.
Inspect teeth after initial runs and at regular service intervals, check for looseness or wear, and replace if you see significant damage to ensure reliable performance.
