GPH 346 Helicopter Seesaw Linkage HI0403201 Compatible Part by Hirobo  [HI0403201]

Functional Notes for GPH 346 Seesaw

This Hirobo seesaw is an RC-scale linkage component identified by model HI0403201 and matched to the GPH 346 family naming. It is presented as a direct replacement-style seesaw used in helicopter rotor linkages, intended to restore or maintain correct control geometry without implying outside vehicle use.

Focus on fit and functionality: confirm the component seats correctly at existing linkage points, check for binding or endplay, and ensure it travels smoothly through the control arc. The seesaw transmits collective and pitch commands between cyclic and swash elements, so precise alignment matters for stable tracking and response.

Fitment tips: examine mating pivots and fasteners for wear prior to installation, match link lengths and ball or snap joint types to the original setup, and confirm full range and centring after installation. When tuning, small incremental changes to seesaw position can refine pitch curves and cyclic balance; test progressively after each tweak.
