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

Second stage gear for Eagle Freya EX-EP helicopters

This second gear is supplied as a replacement for the Eagle Freya EX-EP family and is aimed at model technicians and hobbyists performing drivetrain service. The 101T tooth count is the defining feature that affects overall gear ratio and consequent control feel when matched with the existing pinion and spur components.

Practical guidance: ensure correct alignment within the Freya EX-EP gear train, set the mesh carefully with the pinion while the assembly is static, and run the rotor slowly after fitting to observe tooth engagement. Adequate bearing support and correct mesh reduce vibration and help keep tail and cyclic responses stable.

Fitting notes: remove necessary covers and secure the rotor head for safe access, support the main shaft while swapping the gear to avoid disturbing bearing preload, and tighten retention hardware per the manufacturer's torque recommendations. Complete a low-rpm ground spin check before attempting full-power flight.

Select this gear when restoring worn drivetrain parts or when adjusting mid-range gear ratios; always verify fitment and mesh quality prior to flight.
