Mugen MTX-5 18T Pinion Gear by Arrowmax AM-MTX4-T0726  [AM-MTX4-T0726]

Pinion Gear for MTX-5

This Arrowmax pinion is designed as an RC-scale replacement pinion for Mugen MTX-5 chassis use, specified as an 18T motor pinion made from 7075 hard material. It serves as a direct gear interface with the motor output to change gear ratio, affecting acceleration, top speed, and motor load in model setups.

Fit and compatibility are focused on the MTX-5 platform; when replacing the pinion ensure correct mesh with the spur gear, confirm shaft fitment and set backlash to the chassis manufacturer’s recommended tolerances. Use appropriate thread locking or retaining methods expected in RC maintenance to secure the pinion to the motor shaft.

Tuning notes: swapping to an 18T pinion will move the drivetrain toward higher top speed compared with smaller tooth counts while increasing load on the motor and ESC. Balance pinion choice with motor timing, ESC settings, and battery selection to achieve the desired trade-off between acceleration and sustained speed in RC practice or track sessions.
