Hirobo HI2511009 M3 x 74 Cross Member for Helicopter Frames  [HI2511009]

Replacement Cross Member for RC Helicopters

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 diameter and length specification as shown in the product name, and the component functions as a structural connector within Hirobo helicopter assemblies.

Typical use cases include restoring frame rigidity between boom supports or transverse mounts on the main frame. When fitting this part, confirm thread engagement and alignment with your existing M3 fasteners, ensure there is no interference with nearby components, and make sure the part sits flush to preserve correct geometry. Replacing a damaged cross member often helps recentre components and cut down vibration that can upset flight trim.
