Hirobo HI0412235 Precision Pitch Arm for Sceadu SD-G  [HI0412235]

Precision pitch linkage arm for SD-G rotor heads

This RC pitch arm is intended for installation on the Sceadu SD-G series rotor head assembly and serves as a direct replacement to help restore correct linkage geometry and consistent pitch response.

The part mounts in the original location so no airframe modification should be necessary. When fitting, ensure the control linkages operate freely across the entire pitch envelope and that collective and trim return to neutral before attempting flight.

Used in maintenance routines and tuning sessions, the arm replaces worn components to re-establish accurate cyclic and collective throws and to provide a reliable pivot for precise pitch adjustments at the workbench or at the field.
