MUGEN MTX-5 Second Gear 21T 7075 Hard Aluminum - Arrowmax AM-MTX5-T2712  [AM-MTX5-T2712]

Precision 21T second gear for MTX-5

This Arrowmax AM-MTX5-T2712 spare is an RC-scale second gear made for use with MUGEN MTX-5 transmissions. The component is a 21-tooth second gear machined from 7075 hard aluminum and supplied as a single replacement unit for gearbox assemblies.

Use this part for scheduled replacement, maintenance checks, and fine gearbox tuning. As a direct spare for MTX-series drivetrains where a 21T second gear is required, its 7075 construction focuses on wear resistance and dimensional stability under load.

Installation notes: verify existing gear mesh, confirm correct shimming and backlash before running, and inspect the mating pinion and bearings for wear. Use standard RC-safe tools and avoid overtightening housing fasteners that can deform seating surfaces.
