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

Cross bar for GPH 346 GT

This cross bar is a RC-scale replacement part identified as HI0403269 by Hirobo, specified for the GPH 346 GT family. The product name indicates a fixed length cross member (L=102) intended for use within the helicopter's frame or linkage assemblies where a precise 102mm span is required.

Compatibility follows the GPH 346 GT designation in the model name. The part functions as a structural connector, so correct alignment and secure fastening are important to preserve flight geometry. Inspect mating points on your airframe before installation to confirm fitment against the GPH 346 GT layout.

Installation notes: remove the original cross bar or access the mounting area, position the HI0403269 so that the L=102 dimension aligns with the frame datum, and secure it using the original hardware or equivalent fasteners rated for RC model use. Perform a ground check of linkages and collective/tracking before flight.

Tuning role: as a fixed-length cross member, this component helps maintain consistent geometry between attachment points; swapping lengths or replacing a worn bar can affect cyclic response and hover trim, so re-check rotor tracking and control neutral positions after replacement.
