Seesaw Replacement for Eagle/Freya/EX/SX - HI0404232 by HIROBO  [HI0404232]

Seesaw for Eagle/Freya/EX/SX Airframes

This HIROBO HI0404232 seesaw is supplied as a direct replacement part for radio-controlled helicopter rotor linkages, designed to restore correct control geometry and predictable flight characteristics. It is offered as an RC-scale component and not for any full-size aircraft application.

Compatibility is defined by the Eagle/Freya/EX/SX common-parts family specified by HIROBO; confirm your model uses the same seesaw profile before fitting. The component operates as the pivot in the swash-to-rotor linkage and directly affects cyclic response when the rest of the linkage geometry is correct.

Swapping the seesaw is straightforward: remove the old unit, move any pins or bearings if required, and fit the replacement while ensuring linkage alignment and a neutral swash plate. After installation, perform bench control sweeps and trim checks to verify full travel and correct centering before flying.

Tuning note: replacing a worn seesaw with this HIROBO part can restore crisp cyclic inputs and remove play that causes inconsistent control feedback. Inspect pushrods and servos for secure fittings and verify there is no binding across collective and cyclic ranges.
