GPH 346 Engine Mount Replacement - HI0403230 by Hirobo  [HI0403230]

Replacement engine mount for GPH 346

This Hirobo HI0403230 engine mount is an RC-scale replacement part engineered to fit the GPH 346 helicopter platform. The text below explains how the mount secures the engine assembly to the frame and helps maintain correct drivetrain alignment during both flight and bench tuning.

Compatibility is intended for the GPH 346 series as indicated by the product designation, so check your chassis layout and mounting points before ordering. The mount provides a fixed interface between the engine or motor assembly and the airframe, helping to control vibration transfer while preserving gear mesh and shaft alignment when the helicopter is running.

Installation notes: gather standard hobby workshop tools, clean mating surfaces, and confirm bolt patterns match the existing mount. Tighten fasteners progressively to prevent distortion, then check driveline alignment at low throttle before full-power testing. For tuning, confirm the mount position when adjusting engine placement to optimise gear engagement and to reduce vibration that can affect cyclic stability.
