Replacement slide blocks for GPH 346

This slide block set is an RC-scale replacement component for the GPH 346 helicopter line. It serves as a direct swap for worn or fatigued slide blocks within the tail linkage assembly, restoring intended movement and alignment without requiring major changes to the airframe.

The parts are intended for model maintenance and tuning: they locate and guide small moving linkages on the tail system and help preserve consistent geometry for predictable control response. This makes them useful when addressing play in the linkage or when performing setup adjustments after modification or repair.

Installation is straightforward for those familiar with helicopter tail assemblies. Typical steps include removing the affected linkage, swapping the slide block(s), checking free movement through the full control range, and confirming neutral positions before flight testing. No special tools are specified here; follow standard safe maintenance practices and confirm fit before flight.
