Eagle Freya EX-EP Second Gear 101T - HI0307024 by Hirobo  [HI0307024]

Replacement second gear for Eagle Freya EX-EP

This replacement second gear is specified for the Eagle Freya EX-EP helicopter line and is presented as an RC-scale drivetrain component for hobby maintenance and setup. The 101T designation identifies the tooth count, which affects gear ratio and collective response when paired with the existing pinion and spur gearset.

The article focuses on practical compatibility and tuning roles: verify alignment with the Freya EX-EP gear stack, check mesh with the pinion under static conditions, and inspect tooth engagement after a short run-in at low throttle. Proper mesh and bearing support reduce vibration and help maintain stable tail and cyclic response.

Installation notes: remove the canopy and main rotor head as required for safe access, support the main shaft while replacing the gear to avoid bearing preload changes, and confirm retention hardware torque per your model's service manual. After installation, perform a ground spin test at low rpm to confirm smooth engagement before full flight.

Choose this gear when replacing worn teeth or when adjusting gear ratios for intermediate drivetrain tuning, and always confirm fitment before flight operations.
