This is an RC-scale seesaw linkage listed under Hirobo HI0403263 intended for use with the GPH 346 GT designation shown in the product name. The component focuses on the seesaw pivot function used within the tail linkage system of compatible model helicopters.
The role of this seesaw link is primarily mechanical: it provides a pivot point and load path for tail linkages to translate servo movement into controlled tail rotor action. Inspect the part for fit against your helicopter's linkage geometry before installation, and verify that ball studs or fasteners align without forcing the control rods.
Installation notes: fit the seesaw to the existing tail assembly points, secure the mountings evenly, and confirm free but firm movement of the pivot. During initial setup, cycle the tail servo slowly to observe travel and ensure no binding occurs across the full range used in flight. Adjust linkage length or servo endpoints on the transmitter as needed to restore correct neutral and travel limits.
