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

Replacement structural bar for GPH 346 GT

The HI0403269 cross bar from Hirobo is an RC-scale replacement part intended for the GPH 346 GT series. The L=102 marking indicates a fixed 102mm span, used where precise spacing is required between frame linkage points.

This component is matched to the GPH 346 GT designation found in the model name. As a load-bearing connector, secure placement and correct alignment are essential to preserve intended flight geometry. Always inspect mounting faces on the airframe to ensure compatibility with the GPH 346 GT layout.

Fitting guidance: gain access to the mounting area or remove the old bar, align the HI0403269 so the L=102 measurement corresponds to the frame reference, and attach with original or equivalent-grade fasteners suitable for RC use. Conduct a ground-based verification of linkages and collective/tracking once installed.

Tuning note: this fixed-length member maintains geometric relationships across attachment points; substituting a different length or fitting a worn component can change cyclic feel and hover trim, so repeat rotor tracking and neutral checks after replacement.
