HIROBO HI0404232 Replacement Seesaw compatible with Eagle/Freya/EX/SX  [HI0404232]

Replacement seesaw: fit and wear notes

The HIROBO HI0404232 seesaw is intended as a direct spare for RC helicopter rotor linkages to recover correct geometry and consistent control feel. It is an RC-scale replacement and not designed for use on manned aircraft.

Fitment follows the Eagle/Freya/EX/SX common-parts grouping identified by HIROBO; check the part outline against your airframe before ordering. The seesaw is the mechanical pivot linking the swash plate to the rotor head and plays a central role in cyclic behaviour when properly installed.

For replacement, remove the existing seesaw, transfer any necessary pins or bearings, and install the new unit ensuring correct alignment and a neutral swash plate. Run ground checks for full travel and centering prior to flight.

Durability tip: inspect this replacement periodically for signs of wear or play. Using a fresh HIROBO seesaw can eliminate slop that degrades control precision, and helps preserve consistent tuning across sessions.
