M3 x 74 Cross Member Compatible with Hirobo - HI2511009  [HI2511009]

Cross Member Details and Use

This HI2511009 cross member from Hirobo serves as a replacement component for helicopter airframes needing a straight M3 cross tie. The M3 x 74 marking indicates the threaded diameter and length, and the part is designed to sit as a structural link within Hirobo airframe assemblies.

In practical terms, this component is often fitted between boom supports or across transverse frame mounts where alignment and stiffness are critical. Before installing, check thread engagement, clearance to adjacent parts, and that the part sits flush to preserve correct alignment. Swapping out a worn or bent cross member typically improves centering and reduces flight vibration issues.
