SCEADU SD Elevator Link Shaft Replacement — HI0412135 by Hirobo  [HI0412135]

Product details and fit

This replacement elevator shaft is an RC-scale helicopter spare designed as a direct swap for SCEADU SD elevator linkage assemblies and restores the elevator linkage without changing control geometry when fitted correctly.

Installation notes: inspect the rotor head and linkage bearings for wear before installing the shaft, align the control horn and retaining fasteners precisely, and follow your model's torque recommendations to avoid introducing play. Use thread locker only where the original assembly specifies it and avoid over-torquing small screws.

Tuning role: the shaft itself does not alter aerodynamics or control rates, but a straight, properly seated shaft is essential to maintain crisp elevator response. Replace the shaft if you detect endplay, bending, or wear at the retaining points, since those defects produce sloppy control feel.
