This Hirobo cross member, M2 x 20, is an accessory for Hirobo helicopter general parts. It functions as a short connector that helps hold together frame segments and secures fittings where M2 metric fasteners are employed.
Installation guidance: seat the cross member flush with mating components, choose M2 screws of suitable length to avoid bottoming out, and confirm alignment before applying final torque to prevent frame distortion. The part listing does not imply inclusion of screws or mounting hardware.
Tuning role: by preserving local stiffness and consistent geometry at junctions, the cross member can enhance repeatability of control linkages and limit setup drift when mounted with correct technique.
