GPH 346 GT Slide Block Replacement for RC Helicopters - Hirobo HI0403264  [HI0403264]

GPH 346 GT Slide Block Summary

This replacement slide block fits GPH 346 GT models and is supplied under Hirobo part number HI0403264. It sits in the rotor-head and linkage assemblies where it guides motion and maintains alignment for cyclic and collective controls.

Installation is straightforward for experienced technicians: remove the worn block, transfer any retaining hardware, fit the new slide block in the same orientation, and check for smooth, wobble-free travel through the full control range. After fitting, ensure there is no binding and verify control throws; small blade or linkage centring tweaks may be needed to restore correct rotor-head geometry.

During tuning and routine checks this slide block reduces play at linkage joints and helps preserve consistent control geometry across multiple flights. Regular inspection for wear and free movement keeps cyclic response predictable and simplifies pitch tracking when you set up or trim the helicopter.
