Tune Your Drivetrain with Arrowmax AM-364021

The Arrowmax AM-364021 pinion is crafted from 7075 hard aluminium to deliver a strong yet lightweight gear solution. Its construction targets hobbyists who want reliable performance without adding needless weight.

Why the 64P 21T Matters

The 64-pitch, 21-tooth count gives a predictable gear ratio and smooth engagement with matching spur gears. Using 7075 aluminium improves resistance to deformation and helps maintain gear geometry under load.

Compatibility Tips for Builders

This pinion suits a wide variety of RC models when a 64P pinion is required. Before installing, check mesh settings and ensure the gear aligns cleanly with your spur for quiet, efficient operation.

What should I check before fitting this pinion?

Measure your existing gear pitch and tooth count, plus confirm motor shaft type. Matching all three ensures proper fit and prevents premature wear.

Does the alloy require special care?

7075 aluminium is robust but should be checked regularly for wear and correct mesh. Periodic inspection and correct setup extend service life.

Will this change my gear ratios dramatically?

To alter ratios, change tooth counts relative to your spur. This 21T pinion is a standard option, so ratio changes depend on your chosen spur gear size.
