Arrowmax 1st pinion compatible with XRAY NT1

This Arrowmax 1st gear pinion is an RC replacement part aimed at the XRAY NT1 range. Cut from 7075-T6 aluminium and given a hard coating, it replaces the 1st gear pinion and is designed to mesh with NT1 spur gears without modification.

Tooth count options include: 16T, 17T, 18T, 19T, 20T, 21T, 22T and 23T. These increments let you tune the balance between acceleration and top speed to suit different circuit types and motor setups.

Fitment notes: the pinion conforms to the NT1 clutch form factor, so confirm shaft diameter and clutch compatibility before fitting. When assembling, set a correct mesh and test clutch engagement across throttle ranges to prevent undue wear.

Tuning summary: changing the 1st pinion provides a simple mechanical method to adapt gearing for track or driver needs. Used with standard NT1 spur gears, this part alters gearing only and typically does not require motor or ESC adjustments.

Which tooth count improves corner exit?

A lower tooth count tends to improve acceleration and corner exit, which helps on twisty tracks. Match selections to your motor's torque curve for best results.

How should I check gear mesh?

Set a small, even backlash and rotate the drivetrain by hand to ensure smooth engagement across the gear faces. Adjust until noise is minimal and teeth contact is even.

Does the hard coating change performance?

The hard coating improves surface wear resistance and helps maintain tooth profile under load, which supports consistent gear performance over time.
