GPH 346 Slide Block Replacement - HI0403217 by Hirobo  [HI0403217]

GPH 346 Slide Block Overview

This slide block is a scale RC replacement within the GPH 346 parts family, supplied as HI0403217 by Hirobo. It is intended as a direct service component for assemblies using the GPH 346 sliding arrangement and should be treated as a like-for-like maintenance part rather than an upgrade.

For installation, experienced model technicians should remove the worn block from the slide rail or linkage assembly, inspect mating faces and fasteners for wear, then fit the replacement making sure the sliding path is free of debris. Confirm smooth travel and correct alignment before flight testing.

During setup and tuning the slide block affects linkage freedom and repeatability of control inputs, so fitting a degraded block replacement can reduce play and restore predictable response. Regular inspection during maintenance cycles keeps control linkages consistent.
