Shuttle RG Collect Link Left Carbon for Precision Tuning - HI0402730 by Hirobo  [HI0402730]

Collective linkage for fine tuning

This Hirobo HI0402730 collect pitch arm is a replacement part designed for the Shuttle RG family, serving as the left-side collect pitch linkage made from carbon. It forms the direct mechanical connection within the collective pitch system and is offered for Shuttle RG configured hobby helis.

As a stiff carbon arm, this component reduces flex-related movement under load compared with standard plastic pieces, improving repeatability when adjusting collective curves. The arm is intended to interface with the Shuttle RG's existing linkage hardware and servo linkages; measure your linkage geometry to ensure compatibility prior to fitting.

Fitment steps: remove the factory left collect pitch arm following your model's removal instructions, align the HI0402730 with the collective bellcrank and servo linkage, and secure with the original fixings. Apply thread locking where specified and confirm servo centering and travel limits prior to flight. Monitor the arm for signs of cracking or delamination and replace if required.

Tuning note: installing this carbon collect pitch arm can make collective inputs more predictable, which is helpful when dialling in pitch curves. Re-check trims and carry out cautious hover tests after installation to confirm the new stiffness suits your setup.
