Mugen MTX-5 18T Pinion Gear 7075 Aluminum - AM-MTX4-T0726 by Arrowmax  [AM-MTX4-T0726]

MTX-5 Pinion Replacement

This Arrowmax pinion is an RC-scale replacement made for use on the Mugen MTX-5 chassis, specified as an 18T motor pinion machined from 7075 hard aluminum. It couples directly to the motor output to alter the gear ratio, which changes acceleration, top speed and the load placed on the motor in everyday model setups.

Fit and compatibility are centred on the MTX-5 platform; when fitting this pinion verify correct mesh with the spur gear, confirm motor shaft diameter and keying, and set backlash to the chassis manufacturer's recommended tolerances. Use the appropriate thread locker or retention method used in routine RC maintenance to secure the pinion to the motor shaft.

Tuning notes: moving to an 18T pinion will bias the drivetrain toward higher top speed compared with smaller pinions while increasing motor and ESC load. Match pinion choice with motor timing, ESC configuration and battery type to get the right balance between initial acceleration and sustained speed for practice or race sessions.
