MUGEN MTX-5 21T Second Gear Precision Replacement - Arrowmax AM-MTX-T2719  [AM-MTX-T2719]

21T second gear tailored for MTX-5

The Arrowmax AM-MTX-T2719 is intended as a dedicated 2nd gear for the MUGEN MTX-5, offering a direct replacement option for hobbyists. Machined from 7075 hard aluminum as noted in the model designation, the gear aims to enhance wear resistance and sustain consistent gear mesh during regular driving and competition use.

Role and tuning: placed as the gearbox second stage in the MTX-5, the 21T gear affects the intermediate ratio and therefore has a direct influence on mid-range tractability versus top speed when used with various pinion and spur setups. Consider this gear when evaluating drivetrain sensitivity or when replacing a worn steel item to reduce wear on adjacent components.

Installation notes: ensure the tooth count is 21T and confirm proper centre-to-centre mesh before final assembly, examine bearings and shaft for play, and apply a light smear of RC-specific gear grease at the tooth root only if needed. The unit is supplied as a single gear for direct fitment in compatible MTX-5 gearboxes.
