This pair of collective pitch levers, supplied as A and B, fits directly into the rotor head collective pitch linkage used on Hirobo Eagle, Freya, EX and SX helicopters that share the same common parts grouping. The components are machined metal and prepared for straightforward RC workshop replacement.
When fitted the levers translate servo motion into blade pitch changes, so achieving correct fit and keeping lateral play to a minimum are important for predictable cyclic response and a stable hover. During installation, confirm that mounting holes line up with the rotor head and that the pivots move freely without binding; inspect for any excess slop once the head is at neutral pitch.
These parts are supplied as ready-to-install service items intended to restore or maintain collective linkage geometry during routine tuning and repairs.
