GPH 346 GT Cross Bar L=102 - HI0403269 by Hirobo  [HI0403269]

GPH 346 GT replacement cross bar

This cross bar is an RC-scale replacement identified as HI0403269 by Hirobo, designed for the GPH 346 GT family. The designation L=102 denotes a fixed 102mm span intended for use in the helicopter frame or linkage assemblies where that precise distance is required.

Compatibility aligns with the GPH 346 GT naming in the model reference. As a structural connector, the bar relies on correct alignment and secure fastening to maintain flight geometry. Inspect the mating points on your airframe to confirm the fit with the GPH 346 GT layout before proceeding.

Installation notes: remove the original cross bar or access the mounting area, seat the HI0403269 so the L=102 measurement matches the frame datum, and fasten with the original hardware or equivalent RC-grade screws. After installation, perform a ground check of linkages and collective/tracking prior to flight.

Tuning role: because this is a fixed-length cross member, it preserves geometry between attachment points; changing lengths or replacing a worn bar can alter cyclic response and hover trim, so re-check rotor tracking and control neutral positions after replacement.
