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

How the seesaw affects cyclic control

This HIROBO HI0404232 seesaw is offered as a replacement component for radio-controlled helicopter rotor linkages to help restore precise cyclic geometry and predictable control inputs. It is supplied as an RC-scale part and not suitable for any real aircraft.

Compatibility follows the Eagle/Freya/EX/SX common-parts family detailed by HIROBO; confirm the seesaw outline matches your airframe before installation. The seesaw functions as the pivot in the swash-to-rotor linkage and directly influences cyclic feel when the linkage geometry is correct.

To install, remove the original seesaw, transfer any bearings or pins if applicable, and fit the replacement while ensuring correct alignment and a neutral swash plate. Conduct bench control sweeps and trim adjustments to confirm correct centering and travel before flight.

Tuning advice: swapping in this HIROBO seesaw can sharpen cyclic feedback and remove inconsistent inputs caused by wear. After fitting, recheck servo endpoints and linkage security to maintain reliable tuning results.
