Function and positioning in the drivetrain

This 21T counter gear is an RC-scale replacement part specified by the product name for the Eagle Freya EX-EP line. It is intended as a drivetrain component inside the model helicopter transmission where correct tooth count and mesh affect tail and main rotor behaviour.

Technicians commonly fit this gear when restoring engagement geometry after wear or during component swaps in rebuilds. Always check for smooth rotation and correct axial spacing before completing the installation to prevent accelerated wear.

Fitment reminder: confirm hub alignment and clearance relative to the spur and pinion, inspect related bearings and shafts for play, and use the recommended fasteners to maintain the original gear mesh. The part is described here solely as an RC helicopter component.

What signs indicate the 21T gear needs replacement?

Look for pitting, uneven tooth wear, or deformation on the 21T gear teeth and check for increased backlash. Any abnormal noise under load or visible wear patterns suggest replacing the gear to protect mating components.

How often should I inspect this gear?

Inspection intervals depend on use, but check gear condition during routine maintenance or after heavy flights. Inspect tooth profiles and bearing support for play each time you service the drivetrain.

Can lubrication extend the gear life?

Proper lubrication of mating gears and bearings reduces wear and noise. Use lubricants suitable for small RC gear trains and avoid over-application that can attract debris.
