Hirobo HI0414499 Counter Gear Shaft for Turbulence D3  [HI0414499]

Service counter gear shaft compatible with Turbulence D3

This counter gear shaft is an OEM-style replacement part intended for the Turbulence D3 helicopter parts set. It forms the rotating axis in the counter gear assembly and is supplied as a single replacement to support gearbox repairs and routine upkeep.

Installation guidance: access the counter gear area through the gearbox or tail case following official service procedures, examine nearby gears and bearings for wear before fitting the new shaft, and confirm correct gear mesh and endplay during reassembly. Use appropriate RC tools and adhere to torque recommendations to avoid stressing components.

Tuning commentary: the shaft is integral to drivetrain alignment and tail drive smoothness. Swapping out worn or damaged shafts during maintenance reduces gear play, preserves mesh geometry, and helps deliver consistent tail characteristics when tuning the model.
