Hirobo HI0414168 Counter First Gear Shaft DTDS  [HI0414168]

Counter first gear shaft for Eagle Freya

This HIROBO HI0414168 counter first gear shaft DTDS is an RC-scale replacement part intended for the Eagle Freya helicopter parts line. It serves as the intermediate shaft in the counter gear train and is used when restoring correct gear mesh or replacing a worn component after flight damage.

The description focuses on fitment and function rather than dimensions; installers should treat the shaft as a direct swap part for the Eagle Freya gear assembly. During service, confirm the shaft seating and the condition of associated bearings and spur/pinion gears to avoid binding and uneven wear.

Installation tips: remove the rotorhead and gear cover to access the counter gear train, inspect mating gears for chipped teeth, fit the shaft into its bearing bores, verify axial play is within the model's allowed tolerance, and rotate the assembly by hand to confirm smooth mesh before reassembly and test hover.
