XRAY NT1 2nd Gear 23T by Arrowmax AM-NT1-338523  [AM-NT1-338523]

2nd Gear 23T for NT1

This 2nd gear pinion is an RC-scale replacement part made for the XRAY NT1 platform, supplied by Arrowmax under the AM-NT1-338523 designation. Machined from 7075-T6 aluminium and given a hard coating, the 23-tooth unit focuses on consistent mesh with NT1 spur gears while keeping rotational mass low for predictable driveline response.

Intended role and tuning notes: fit this gear when you need a specific final ratio change or to match motor pinion choices during setup. The part interfaces directly with the NT1 gearbox train; check gear mesh and endplay when installing, and verify run-in friction is stable before full-power runs.

Installation tips: use the existing clutch/pinion mounting method on the NT1, hand-tighten to seat then back off slightly for proper engagement, and confirm the hard-coated surface clears the spur without binding. The same design family includes multiple tooth counts for ratio selection, so change teeth count to adjust acceleration versus top speed while staying within NT1 drivetrain limits.
