Hirobo HI0402729 Carbon Right Collective Pitch Arm for Shuttle RG  [HI0402729]

Right Collective Pitch Arm - Carbon for Shuttle RG

This RC right-side collective pitch arm is supplied by Hirobo for the Shuttle RG series and is offered as a carbon replacement to mate with the helicopter's collective pitch linkages.

Built for repair and setup refinement, the part replaces worn components to re-establish a linear connection between the servo and main rotor pitch control. The carbon construction favours stiffness and dimensional stability so pitch geometry stays consistent under load.

Installation advice: remove the existing arm using the same linkage hardware, check spline engagement and mounting orientation, fit the carbon unit in the same location, and bring fasteners up to the original torque while ensuring the arm moves freely through the full pitch sweep. Check rotor tracking and servo centring as part of the final setup.

Tuning guidance: because this is a straight replacement, it preserves factory geometry; any change to arm length or linkage layout elsewhere requires re-checking end points and transmitter sub-trim before flight to prevent over-travel faults.
