Mechanical plate for GPH 346

This Hirobo HI0403240 mechanical plate is an RC-scale replacement part intended for use with assemblies that reference GPH 346 in their parts lists. The plate serves as a mechanical mounting interface within the helicopter's drivetrain area, providing a stable surface for adjacent components and helping keep gear and shaft alignment consistent during operation.

Installation focus should be on correct alignment and hardware integrity rather than on performance tuning. Use the original mounting points and appropriate fasteners, verify concentricity of mating shafts, and check clearances around moving parts before first flight. Small misalignments at this mounting plane can transfer to rotor or tail gear behaviour, so take time to align and secure the plate with even torque.

For routine maintenance, inspect the plate for cracks, deformation, or wear at fastener holes after a hard landing or extended running. Cleaning mating surfaces and confirming that adjacent bearings and gears sit flush will reduce play and help preserve predictable handling. This component is described and presented strictly as an RC accessory sized for model helicopters.
