Sceadu SD-G Pitch Arm Replacement - Hirobo HI0412235  [HI0412235]

Replacement pitch arm for Sceadu SD-G heads

This is an RC-scale pitch arm intended for use with the Sceadu SD-G series rotor head assembly. It functions as a direct replacement component to restore linkage geometry and maintain predictable pitch response in hobby helicopters.

The component is designed to occupy the same mounting location as the original pitch arm, allowing replacement without modifying the airframe. During installation confirm the control linkages move freely through the full pitch range and that collective and trim settings return to neutral before flight.

In routine maintenance and tuning workflows the part replaces worn or damaged arms, helping re-establish correct cyclic and collective throws and providing a consistent pivot point for fine pitch adjustments on the bench or at the flying field.
