Shuttle Challenge Rotor Head Seesaw Link - HI0402802 for Shuttle Challenge by Hirobo  [HI0402802]

What the Shuttle Challenge seesaw does

This is an RC-scale seesaw designed as a direct swap for the Shuttle Challenge rotor head assembly. The part transmits swashplate inputs into blade pitch movement and is intended for scale head tuning as well as routine servicing.

The product name specifies fitment: it is aimed at Shuttle Challenge rotor head assemblies. Do not presume compatibility with different head designs without checking pivot geometry and linkage layout. The seesaw is intended to integrate with the standard set of head bearings and linkages used in collective/cyclic systems.

Installation overview: remove the rotor head cover, document linkage positions, extract the old seesaw and fit the replacement with correct pivot alignment, then secure link connections. Rebalance blade pitch at zero collective and confirm smooth travel through the full pitch envelope before flight.

Tuning notes: the seesaw is a fine tolerance linkage that influences neutral pitch and the relationship between collective and cyclic inputs. Even minor mispositioning or wear can shift the collective midpoint or alter cyclic feel, so accurate placement and low play are essential for repeatable handling.
