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

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

Fit this part to replace worn or damaged root ends that reduce control fidelity. The description concentrates on fit, orientation, and the component's role during setup and tuning rather than providing hardware dimensions. For installation, check that connection points match the existing shuttle linkage, inspect mating hardware and bearings for wear, and tighten fasteners to the airframe manufacturer's recommended torque using the correct tools.

When tuning, ensure the shuttle assembly moves freely and that no binding occurs at the root end through full control throw. Replacing a degraded root end can restore smooth linkage action and help maintain predictable cyclic response as part of standard maintenance.
