GPH 346 York Side Plate Replacement HI0403204 by Hirobo  [HI0403204]

GPH 346 York Side Plate (HI0403204)

The Hirobo HI0403204 side plate is a direct-fit replacement panel for GPH 346 York model helicopters. It restores the fuselage side to maintain structural alignment and supports rotor-head geometry during maintenance and setup.

Installation is straightforward for hobbyists familiar with helicopter service: remove the damaged plate at the existing mounting points, transfer any bearings or linkages if required, and secure the replacement using the original fasteners. Clean aluminium contact surfaces and verify alignment of the transmission and rotor links after fitting.

For tuning, the side plate helps preserve consistent gear mesh and frame geometry; combined with routine checks of the swashplate, rotor head and linkages it supports predictable control response. Make small incremental adjustments and perform a cautious hover test before returning to full-power flight.
