SCEADU SD Elevator Shaft Replacement for Accurate Fit - HI0412135 Hirobo  [HI0412135]

Elevator shaft specifications

This replacement elevator shaft is supplied as an RC-scale helicopter spare intended to directly replace the SCEADU SD elevator linkage shaft, helping to return geometry and function without altering control ratios when installed correctly.

Installation notes: examine the rotor head and linkage bearings for signs of wear before fitting, ensure the control horn and shaft are correctly aligned, and use the same torque and retention practice as the original assembly to prevent introducing play. Only apply thread locker where the original design required it and avoid over-tightening fine screws.

Tuning considerations: while the shaft does not change aerodynamic behavior, a straight, correctly installed shaft is critical for precise elevator feel. Replace if you notice endplay or visible deformation at retaining positions, as these issues reduce control accuracy.
