Counter gear function and fitment

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.

In practice this gear is used when restoring tooth geometry after wear or when swapping parts during rebuilds. Fit checks should confirm tooth engagement, axial alignment, and free rotation before final assembly to avoid binding or premature wear.

Installation notes: verify hub orientation and clearance with the mating spur and pinion gears, inspect bearings and shafts for axial play, and use correct fasteners to secure the gear without altering gear mesh. This description treats the component as an RC helicopter part only and does not imply real-vehicle use.

How does the 21T tooth count affect mesh?

The 21T number indicates the gear tooth count and dictates the mating geometry with the spur and pinion. Matching tooth counts and correct backlash are vital to prevent skipping and to preserve smooth drive between the main and tail sections.

Is this a direct drop-in for Eagle Freya EX-EP models?

If the part listing cites compatibility with the Eagle Freya EX-EP, it is designed for direct replacement. Still, confirm shaft diameter, keying, and clearance at the time of installation to ensure proper seating and alignment.

Will fitting this gear affect trimming or handling?

After installation check gear mesh under power and watch for vibration or binding. Small drivetrain changes can alter tail behaviour, so re-trim tail control and verify rotor tracking as part of post-install checks.
