Hirobo HI2509010 Seesaw Pin for Eagle SX Helicopter Tail Linkage  [HI2509010]

Seesaw pin for Eagle SX

This is an RC-scale replacement seesaw pin intended for the seesaw assembly on the Hirobo Eagle SX helicopter model. The part is identified by Hirobo as HI2509010 and is supplied as a single replacement component for maintenance and repair of the seesaw linkage path.

In service the pin locates the seesaw pivot and keeps the linkage geometry stable, which affects tail pitch response and overall trim. When servicing or tuning the Eagle SX, inspect the pin for wear and replace it with this HI2509010 unit to maintain original pivot alignment.

Installation is straightforward for hobby-level technicians: remove the head assembly access as required on the Eagle SX, align the seesaw holes, and install the pin in the original seat until fully located. After installation confirm free pivot movement and re-check control linkages before flight. This description refers only to RC helicopter maintenance and tuning practices.
