Engine mount for GPH 346

This Hirobo HI0403230 engine mount is an RC-scale replacement part designed to fit the GPH 346 helicopter platform. The description focuses on its role in securing the engine assembly within the model frame and maintaining proper drivetrain alignment during flight and bench tuning.

Compatibility is limited to the GPH 346 series as indicated by the product designation, so verify chassis layout and mounting points before ordering. The mount serves as a fixed interface between the engine/motor assembly and the airframe, helping control vibration transmission and preserving gear mesh and shaft alignment when the helicopter is running.

Installation notes: prepare basic RC workshop tools, ensure mating surfaces are clean, and confirm bolt patterns match existing mounts. Tighten fasteners progressively to avoid distortion, then verify driveline alignment at low throttle before full-power testing. For tuning, check mount fit when adjusting engine position for optimal gear engagement and to reduce vibration affecting cyclic stability.
