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

Second gear specified for Eagle Freya EX-EP machines

This second gear is offered as a replacement unit for the Eagle Freya EX-EP helicopter family and is intended for RC drivetrain servicing and setup. The 101T tooth count is the key specification affecting the stage ratio and resulting control feel in concert with your pinion and spur sizes.

Use this part when addressing worn teeth or when experimenting with gear ratios: check static mesh alignment with the pinion, confirm concentric bearing support, and run-in the gear at low rotor speeds to evaluate engagement. Correct mesh and bearing condition help cut vibration and stabilize cyclic and tail inputs.

Fitting guidance: remove exterior panels and secure the rotor head to access the gear safely, support the main shaft to preserve bearing preload during exchange, and torque fasteners to the values in your service documentation. Conduct a slow-speed ground spin to ensure proper engagement prior to flight testing.

Opt for this gear to restore worn drivetrain components or to fine-tune gear ratios; always confirm fit and mesh before resuming full operation.
