HUDY 294012 ULTRA-LIGHT Aluminium 12T Pinion - Hard Coated  [HSP-294012]

HUDY 294012 Aluminium ULTRA-LIGHT 12T Pinion

The HUDY 294012 Aluminium ULTRA-LIGHT pinion is a 12-tooth, 48-pitch option crafted for fine-tuning R/C drivetrains. Constructed from light aluminium with a hard-coated finish, it targets small reductions in rotating inertia while improving the contact surface durability for electric R/C applications.

This pinion is described to clarify technical intent rather than to guarantee performance gains: reduced mass lowers inertia at the motor output, and the hard coating helps slow tooth wear in high-rev or marginal mesh scenarios. Choose this part when you need a 12T pinion that matches 48-pitch spur gears and prefer an aluminium alternative to heavier metals.

Fitment advice: inspect gear mesh and set the correct backlash, secure the set-screw to the motor shaft flat, and manually check spur engagement across a few rotations before live testing. To change final drive, select a different pinion tooth count or adjust the spur while keeping 48 pitch consistent to protect gear life.

Opt for this pinion when a light aluminium 12T 48-pitch part with a hardened finish fits your motor and spur selection, and always validate mesh and set-screw tightness during installation.
