Turbulence D3 Counter Gear Shaft - Hirobo HI0414499  [HI0414499]

Replacement counter gear shaft for Turbulence D3

This counter gear shaft is a scaled replacement part meant for the Turbulence D3 helicopter parts range. It functions as the rotating axis within the counter gear assembly and is provided as a single service item to repair or refresh the transmission train inside the model helicopter.

Installation notes: gain access to the counter gear assembly via the gearbox or tail case following the chassis service procedure, inspect adjacent gears and bearings for wear before fitting the new shaft, and confirm correct mesh and endplay when reassembling. Use standard RC tools and recommended torque practices to avoid stressing mating components.

Tuning role: the shaft forms part of the drivetrain that controls gear alignment and the smoothness of the tail drive. Replacing worn shafts during routine service helps retain consistent mesh, reduces play in the gear train, and supports predictable tail behaviour when setting up and tuning.
