Hirobo HI0403264 Precision Slide Block for GPH 346 GT Helicopter Linkages  [HI0403264]

Slide Block Details for GPH 346 GT

This precision slide block is intended as a replacement for GPH 346 GT machines and carries the Hirobo part number HI0403264. It operates within the rotor-head linkage system to guide travel and keep control inputs aligned.

Fitting is best handled by someone familiar with helicopter linkages: remove the old slide block, retain and transfer any fasteners, install the replacement in the same orientation, and confirm smooth, wobble-free operation through the full control sweep. After installation, check for binding and verify throw accuracy; minor linkage or blade centring may be necessary to recover ideal rotor-head geometry.

For tuning and upkeep this slide block reduces slack at connection points and helps hold stable control geometry over repeated flights. Periodic inspection for wear and unobstructed movement maintains reliable cyclic feel and simplifies pitch tracking when you tune the head.
