MUGEN MTX-5 2nd.GEAR 21T (7075 HARD) by Arrowmax AM-MTX5-T2712  [AM-MTX5-T2712]

Second gear for MTX-5

This Arrowmax spare is an RC-scale second gear intended for use with MUGEN MTX-5 related transmissions. The piece is described by the maker as a 21-tooth second gear made from 7075 hard aluminum and is supplied as a single replacement part for gearbox assemblies.

The item is intended for routine replacement, maintenance checks, and fine-tuning of gearbox engagement. In practical terms it serves as a direct spare for MTX-series drivetrains where a 21T second gear is required, and its 7075 material indicates a focus on wear resistance and dimensional stability under load.

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