GPH 346 Compatible Seesaw Linkage HI0403201 Hirobo  [HI0403201]

Product Brief: 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.

Key fit and operation points include checking that the part lines up with existing pivot points, confirming freedom from binding across the control arc, and checking for any endplay. Because the seesaw carries collective and pitch inputs between cyclic and swash parts, alignment precision will influence tracking and control feel.

Installation advice: inspect mating pivots and fasteners for wear before installing, ensure link lengths and ball or snap joints match the original assembly, and verify full travel and centring post-fit. For trimming, small, deliberate changes to seesaw position can alter pitch curves and cyclic balance; test progressively and record results.
