GPH 346 GT Linkage Slide Block Upgrade HI0403264 by Hirobo  [HI0403264]

GPH 346 GT Linkage Slide Block Notes

This slide block is supplied as Hirobo part HI0403264 and is intended for use with GPH 346 GT helicopter models. It fits into the rotor-head linkage to control guided movement and preserve alignment during control inputs.

Installers experienced with helicopter systems should remove the old block, move any retaining hardware across, fit the new block in the same orientation, and check for smooth, wobble-free travel over the full range of motion. After installation confirm there is no binding and that control throws are accurate; small adjustments to blade or linkage centring may be required to restore ideal geometry.

Used during tuning and maintenance to eliminate play where linkages articulate, this block helps keep control geometry consistent flight after flight. Regular checks for wear and free travel will maintain predictable cyclic response and ease pitch-tracking adjustments at the field.
