Hirobo HI0402729 Right Collective Pitch Arm Compatible with Shuttle RG  [HI0402729]

Replacement Right Collective Arm for Shuttle RG

This is a right-side collective pitch arm from Hirobo intended for Shuttle RG series helicopters, supplied as a carbon replacement component to work with the collective pitch linkages.

The arm is aimed at repair and setup fidelity, taking the place of worn or damaged parts to restore a direct control path between the servo and main rotor pitch mechanism. The carbon construction favours stiffness and dimensional stability, helping to keep pitch geometry consistent under load.

Fitting guidance: remove the original arm using the helicopter's existing linkage hardware, check spline engagement and correct mounting orientation, install the carbon arm in the same location, and tighten fasteners to match original torque while verifying free movement through the complete pitch range. After fitting, confirm rotor tracking and servo centring.

Adjustment note: as a direct replacement it preserves factory geometry; if you adjust arm length or linkage geometry elsewhere, re-check endpoints and alter transmitter sub-trim before flight to prevent over-travel incidents.
