GPH 346 GT 102mm Cross Bar HI0403269 by Hirobo  [HI0403269]

Fixed 102mm cross member for GPH 346 GT

HI0403269 is a Hirobo-specified RC replacement cross bar intended for the GPH 346 GT range. The L=102 identifies the component as a fixed 102mm connector for frame or linkage assemblies where exact span is necessary.

The product aligns with the GPH 346 GT reference in its model description. Functioning as a structural connector, correct orientation and tight fastening are required to retain designed flight geometry. Inspect connection points on your airframe to confirm they match the GPH 346 GT arrangement.

How to install: access the mount or remove the old bar, position the HI0403269 so that the L=102 dimension aligns with the frame reference point, and secure it using the original mounting hardware or suitable RC-grade alternatives. Perform linkage checks and confirm collective/tracking on the ground after installation.

Tuning impact: as a fixed-length member, this part helps keep attachment geometry consistent; replacing it with a different length or a worn item can influence cyclic response and hover trim, so revalidate rotor tracking and control midpoints after swap.
