Shuttle RG Carbon Replacement Right Pitch Arm HI0402729 by Hirobo  [HI0402729]

Carbon Right Pitch Arm for Shuttle RG Models

This item is a right-side collective pitch arm from Hirobo made for the Shuttle RG line, delivered as a carbon replacement component to interface cleanly with the collective pitch linkages.

Designed for repair and performance stability, the component replaces worn or damaged arms to re-establish linear servo-to-rotor pitch response. Carbon construction increases stiffness and helps retain dimensional accuracy under load, supporting consistent pitch behaviour.

Fitting notes: remove the old arm using the existing linkage parts, verify spline and mounting orientation, mount the carbon arm in the same position, and tighten fasteners to the original torque while confirming free travel across the full pitch range. After fitting, verify rotor tracking and check servo centring.

Setup impact: this arm is a direct replacement to keep factory geometry intact; if you alter lever lengths or linkage angles elsewhere, re-check end points and adjust sub-trim on the transmitter prior to flight to prevent over-travel issues.
