2nd gear 21T for MTX-5

The Arrowmax AM-MTX-T2719 is a dedicated 2nd gear designed for MUGEN MTX-5 platform users looking for a direct, durable replacement part. Machined from 7075 hard aluminum as indicated in the product name, this gear focuses on wear resistance and maintaining consistent meshing under racing and practice loads at RC scale.

Role and tuning: as the second stage in the MTX-5 gearbox, the 21T 2nd gear defines part of the car's intermediate ratio and therefore affects mid-range acceleration and top speed balance when combined with pinion and spur choices. Use this gear when testing drivetrain responsiveness or when replacing a worn steel alloy part to reduce wear on mating components.

Installation notes: confirm the tooth count and center-to-center mesh before full assembly, inspect mating bearings and shaft for play, and apply a light, RC-appropriate gear grease only to the teeth root if required. The component is sold as a single gear piece suitable for direct swap in compatible MTX-5 gearboxes.
