Hirobo HI0304016 Lepton EX SZM seesaw replacement part  [HI0304016]

Seesaw linkage for Lepton EX

This is an RC-scale replacement seesaw (seesaw linkage) listed for the Lepton EX SZM line, intended as a direct replacement component for the helicopter's head/tail linkage system. The text here follows the product designation and focuses on fit, installation considerations, and the role this part plays during trimming and maintenance.

Compatibility is indicated by the product name targeting Lepton EX SZM assemblies; confirm part numbers on your model before ordering. Installation typically involves replacing the existing pivot linkage in the rotor head or tail bellcrank area and checking neutral positions before flight. As a tuning element, the seesaw determines fine balance between cyclic and tail responses, so verify linkage geometry and servo centring after swap.

Use this part when replacing worn linkage or when restoring correct head/tail neutral geometry; always test hover behaviour and control response after installation to confirm expected tuning results.
