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

Shuttle Challenge seesaw overview

This RC-scale rotor head seesaw is a direct replacement engineered for the Shuttle Challenge rotor head assembly. It functions as the central seesaw linkage that transmits swashplate motion into blade pitch changes, and it is suited for scale helicopter head tuning and scheduled maintenance.

Fitment follows the product name: the item targets Shuttle Challenge rotor head assemblies. Do not assume it will fit unrelated heads without checking the target head geometry and pivot spacing. The component is intended to work with the existing head bearings and links in a standard collective/cyclic layout.

Installation notes, kept deliberately high level: open the rotor head, remove the original seesaw while recording linkage positions, fit the replacement and align pivot points, then secure the link connections and re-establish blade pitch neutrality at zero collective. After reassembly, confirm smooth travel through the full pitch range and ensure no binding in the head before flying.

Tuning impact: the seesaw is a precision linkage affecting neutral pitch and the balance between collective and cyclic inputs. Small misalignment or wear here can shift the collective midpoint and alter cyclic feel, so correct positioning and minimal play preserve predictable control response and make pitch-trim adjustments more consistent.
