Hirobo HI2511009 Cross Member M3 x 74 - Helicopter Cross Member  [HI2511009]

Helicopter cross member

This HI2511009 cross member from Hirobo is an RC-scale replacement part intended for helicopter airframes where a straight M3 cross connection is required. The "M3 x 74" designation refers to the threaded size and length specification as provided in the product name, and the part is intended to serve as a structural connector within Hirobo helicopter assemblies.

In practice this cross member is used where frame rigidity and precise alignment matter, such as between boom supports or transverse mounts on the main frame. When fitting, verify thread engagement and alignment with existing M3 fasteners, check for any interference with nearby components, and confirm the part sits flush to maintain proper geometry. Replacing a worn or bent cross member can restore centring and reduce vibration that affects flight trim.
