Shuttle Challenge Seesaw Linkage HI0402802 Compatible with Shuttle Challenge by Hirobo  [HI0402802]

Overview of the Shuttle Challenge seesaw

This seesaw is an RC-scale replacement part made to fit the Shuttle Challenge rotor head assembly. It acts as the central linkage that converts swashplate movement into blade pitch changes and is suited for scale head setup and tuning work.

Compatibility is defined by the product title: intended for Shuttle Challenge rotor head assemblies only. Confirm head layout and pivot locations before assuming compatibility with other models. The component is intended to mate with the existing head bearings and linkage hardware typical of a standard collective/cyclic configuration.

High-level installation guidance: access the rotor head, note the original link positions, remove the old seesaw, install the new unit making sure pivots align, and secure connections. Re-establish zero-collective blade pitch and verify smooth movement through the full pitch arc prior to flight testing.

Role in tuning: as a precision linkage, this seesaw affects neutral pitch setting and the balance between collective and cyclic inputs. Any misalignment or excessive play can move the collective midpoint or change cyclic characteristics, so careful positioning and minimal slop are important for consistent handling.
