Improve Drivetrain Control with Arrowmax AM-364021

The Arrowmax AM-364021 pinion is produced from 7075 hard aluminum to combine toughness with reduced weight. It is aimed at modellers who want dependable gear behaviour under load.

Performance Traits of the 64P 21T

A 64-pitch, 21-tooth layout provides steady engagement and consistent power delivery to the drivetrain. The 7075 alloy helps the gear retain its profile during extended runs, maintaining efficient transfer from motor to spur.

Use Cases and Compatibility

Compatible with many RC setups that require a 64P pinion, this Arrowmax 64P 21T unit is suitable for routine replacement or selective upgrades. Always confirm pitch and shaft compatibility before fitting.

What checks should I do after installing this pinion?

After fitting, verify gear mesh and run the drivetrain slowly to detect binding or irregular contact. Recheck once warmed in to confirm stable operation.

Are there common upgrade paths using this pinion?

Modellers often pair different spur sizes with a 21T pinion to tune acceleration versus top speed. Keep the pitch consistent and monitor motor load when changing ratios.

Should I inspect this gear regularly?

Yes, periodic inspection for tooth wear and correct mesh is recommended. Replacing a worn pinion prevents damage to the spur and keeps performance consistent.
