GPH 346 Precision L-angle Mounting Bracket - HI0403239 by Hirobo  [HI0403239]

GPH 346 L-angle bracket explained

The Hirobo HI0403239 is an RC L-angle bracket marketed as a replacement or service component for the GPH 346 parts family. Its L-angle layout is intended to locate and secure adjoining assemblies and does not specify any particular fastener or material details.

As a support and alignment component, the bracket supplies a right-angle mount where two structural parts join. Fitted into tail or frame areas, it reduces play and helps retain correct geometry in rotating or pitch-related linkages.

Installation guidance for experienced builders: place the bracket into the designated mounting faces, confirm alignment before final tightening, and use the original screw positions and thread engagement to reduce the risk of stripping. Compare outline and hole spacing with the removed part when replacing a worn bracket to ensure correct fit.

Impact on tuning: install the bracket to lock geometry during setup checks, then verify neutral positions and free travel of any linked controls after fitting. Carry out final trims on linkages or control horns rather than attempting to alter the bracket shape.
