This Hirobo cross member is an M2 x 20 RC-scale part intended for Hirobo helicopter general parts. It provides a compact structural link to join frame sections and establish mounting points where small metric fasteners are required.
Installation guidance: align mating surfaces so the cross member rests flush, select M2 fasteners with proper thread engagement to avoid bottoming out, and verify alignment before final tightening to prevent warping. The item should not be assumed to include mounting screws or extras.
Tuning role: the cross member helps maintain local stiffness and repeatable geometry at component junctions, which can improve the consistency of control linkages and reduce drift when assembled correctly.
