Structural Connector Overview

This HI2511009 cross member from Hirobo is intended as an RC replacement for helicopter frames needing a straight M3 cross connection. The M3 x 74 spec identifies the thread size and length, and the item is used as a load-bearing connector within Hirobo airframes.

Common installations include bracing between boom supports or across transverse mounts on the main frame where stiffness and precise alignment matter. When installing, verify correct thread engagement, clearance with nearby components, and that the part sits flush to preserve geometry. A damaged cross member should be replaced to help bring component centring back and reduce vibration that can affect trim and handling.

What fastener length works with M3 x 74?

Select fasteners that provide full thread engagement without bottoming out; the 74 mm part length is a guide—check your stack height and choose screws that suit the assembled thickness.

Where is this usually fitted on the frame?

It is typically located between boom supports or across transverse mounting points of the main frame where correct spacing and stiffness are required for stable flight.

How does it affect flight trim?

A correctly fitted cross member preserves frame geometry; replacing a distorted piece can restore balance and reduce vibration, which in turn helps keep trim settings consistent in flight.
