GPH 346 Engine Mount for Alignment and Tuning - HI0403230 Hirobo  [HI0403230]

Mount for engine alignment on GPH 346

The Hirobo HI0403230 engine mount serves as an RC-scale replacement part for the GPH 346 helicopter platform. This description emphasises its role in anchoring the engine assembly and preserving drivetrain alignment during both bench tuning and flight operations.

Intended for the GPH 346 series, confirm your frame and mounting points match the product designation before purchase. The mount functions as the fixed connection between the engine or motor and the airframe, helping to manage vibration and maintain correct gear mesh and shaft alignment when running.

Fitting advice: prepare common hobby tools, make sure mating surfaces are clean, and verify the bolt pattern with your current mount. Tighten fasteners incrementally to prevent distortion, then confirm driveline alignment at low throttle before full-power runs. During tuning, check mount placement while adjusting engine position to achieve optimal gear engagement and to reduce vibration that can affect cyclic response.
