GPH 346 Tail Slide Block Set for Linkage Tuning - HI0403010 by Hirobo  [HI0403010]

GPH 346 tail slide block replacements

The Hirobo HI0403010 slide block set is an RC-scale replacement component made for the GPH 346 helicopter line. These blocks serve as direct swap parts for worn or fatigued slide blocks in the tail linkage, restoring intended motion and alignment without major airframe changes.

Designed for routine maintenance and setup, the parts locate and guide small moving linkages on the tail system to preserve consistent geometry and predictable control response. They are useful when removing play in the linkage or after repairs and adjustments to the tail pitch assembly.

Installation is straightforward for hobbyists familiar with tail assemblies. Typical steps include removing the affected linkage, fitting the replacement slide block(s), checking for smooth movement across the full control range, and confirming neutral positions before flight. Follow normal maintenance safety practices and verify correct fit before flying.
