MTX-5 21T Second Gear 7075 Aluminium Upgrade for MUGEN - Arrowmax AM-MTX5-T2712  [AM-MTX5-T2712]

Replacement 21T second gear for MTX-5 drivetrains

This Arrowmax AM-MTX5-T2712 spare is intended for use in MUGEN MTX-5 gearbox assemblies. It is a 21-tooth second gear produced from 7075 hard aluminium and provided as a single replacement component for RC gearboxes.

Use it for routine servicing, fine tuning of gear engagement, and to restore correct drivetrain operation. The 7075 hard aluminium body provides good wear resistance and keeps dimensional accuracy under load for MTX-series setups.

Fitting guidance: check gear mesh, shimming and backlash before running at speed, and inspect the mating pinion and bearings for signs of wear. Employ correct RC tools and avoid over-torquing screws that can warp seating faces.
