Eagle Freya EX-EP Replacement Counter Gear 21T HI0307026 by Hirobo  [HI0307026]

Installation, alignment and checks

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.

Use the gear when renewing worn teeth or swapping parts during a service. Before completing fitment verify axial alignment, correct engagement with the spur and pinion, and that the gear turns freely without binding.

Checklist for fitters: confirm hub orientation and mating clearance, inspect bearings and shaft runout, and secure the gear with appropriate fasteners while maintaining specified mesh. This description applies only to RC helicopter use.
