HIROBO HI0402011 Shuttle Root End for Helicopter Shuttle Assembly  [HI0402011]

This HIROBO HI0402011 shuttle root end is an RC-scale shuttle linkage component intended for use in Hirobo helicopter shuttle assemblies. It functions as the terminal connection point in the shuttle linkage, transferring motion between the cyclic controls and the swashplate or rotor head components in compatible Hirobo helicopters.

Use this part to replace worn or damaged root ends that affect control fidelity. The article focuses on fit, orientation, and the part's role during setup and tuning rather than on hardware dimensions. For installation, verify matching connection points on the existing shuttle linkage, check mating hardware and bearings for wear, and secure fasteners to the manufacturer's recommended tightness using appropriate tools.

During tuning, confirm free movement of the shuttle assembly and that no binding occurs at the root end under full control throw. Replacing this component can restore smooth linkage operation and help maintain predictable cyclic response when used as part of routine maintenance.
