GPH 346 Linkage Slide Block Upgrade for RC Helicopters HI0403010 by Hirobo  [HI0403010]

Tail linkage slide blocks for GPH 346

The Hirobo HI0403010 slide block set is an aftermarket replacement solution for the GPH 346 helicopter family. These components replace worn slide blocks in the tail linkage to help restore intended movement and alignment without modifying the airframe.

They locate and guide small moving linkages on the tail, preserving consistent geometry which contributes to steady, predictable tail response. Use them when addressing control play or as part of a setup after repair or adjustment work.

Installation is standard for tail maintenance: remove the affected linkage, install the new slide block(s), check smooth operation across the full control arc, and confirm neutral settings before flight testing. Follow normal hobby maintenance safety and confirm correct fitment prior to flying.
