Counter Gear Shaft for Turbulence D3 - Hirobo HI0414499  [HI0414499]

Service replacement counter shaft for Turbulence D3

This counter gear shaft is an aftermarket replacement component intended for the Turbulence D3 helicopter parts lineup. It acts as the rotating pin in the counter gear assembly and is sold individually for maintenance or gearbox repairs on the model helicopter.

Installation notes: remove the gearbox or tail case using the recommended chassis service method, check surrounding pinions and bearings for signs of wear prior to fitting, and set mesh and axial play correctly during reassembly. Stick to standard RC toolsets and torque limits to avoid damaging mating parts.

Tuning impact: the shaft helps determine gear alignment and the smoothness of tail transmission. Swapping out a tired shaft during routine servicing helps reduce gear play, preserve correct mesh, and maintain predictable tail response when adjusting setup.
