This Hirobo replacement part is the cooling fan cover stay designed for the GPH 346 helicopter parts family. Its role is to secure the fan cover and keep the cooling assembly stable during normal flight and ground handling. The text focuses on practical fit and function rather than materials or performance claims.
Installation is straightforward for users familiar with GPH 346 airframes: remove the existing cover fasteners, align the stay with the cover and mount points, and secure with the original screws. No special adapters are required when used with stock GPH 346 mounting points, but confirm screw engagement and clearance before flight.
In tuning and maintenance, this stay helps maintain consistent airflow pathing by keeping the fan cover in correct position, which supports predictable cooling behaviour of the fan assembly. Use it as a direct replacement during routine servicing or when a cover mount shows wear.
