Hirobo HI0403234 Collective Pitch Lever Set for GPH 346 rotor head accessory  [HI0403234]

Collective Pitch Lever for GPH 346

This Hirobo collective pitch lever set is an RC-scale replacement accessory intended for use with GPH 346 rotor head assemblies. The levers serve the mechanical role of transmitting swashplate motion to the blade grips and are presented as a direct-fit service part for models that specify GPH 346 components.

Installation is straightforward for hobbyists familiar with rotor head work: remove the rotor head linkage, replace the worn levers, and verify centring and free play before flight. Use the model's existing fasteners and torque to the manufacturer's values, and confirm smooth cyclic and collective response during ground checks.

In tuning and maintenance, these levers are a component-level item for restoring precise pitch response. Inspect for fit at the linkage pivots and ensure bearings or pins in the rotor head are serviceable to avoid introducing slop that can affect control feel.
