GPH 346 Mounting Bracket Upgrade - HI0403230 Hirobo  [HI0403230]

Engine mounting bracket for GPH 346 helicopters

The Hirobo HI0403230 engine mount is provided as a direct-fit, RC-scale replacement for the GPH 346 helicopter platform. Below we outline its function in anchoring the engine assembly and in helping maintain correct drivetrain geometry during tuning and operation.

Use this mount only if your helicopter matches the GPH 346 series mounting layout. The component acts as the solid connection between the engine or motor and the airframe, helping to damp and manage vibration while keeping gear mesh and shaft alignment consistent under power.

Fitting tips: have basic hobby tools to hand, ensure contact surfaces are free of debris, and confirm the bolt pattern lines up with your frame. Apply torque progressively to avoid warping, then check driveline alignment at low throttle. When tuning, re-evaluate mount placement while adjusting engine position to secure optimal gear engagement and minimise vibration that affects flight control.
