Hirobo HI2511009 Cross Member (M3 x 74) - Helicopter Structural Part  [HI2511009]

Component Overview for Helicopter Frames

This HI2511009 cross member from Hirobo is supplied as an RC replacement for helicopter airframes where a straight M3 cross link is required. The "M3 x 74" marking identifies the thread diameter and length, and the part is intended to act as a stabilising connector within Hirobo frame assemblies.

It is commonly used to ensure rigidity between boom supports or across transverse mounts on the main frame. Prior to fitting, check thread compatibility, alignment and clearance with adjacent parts, and ensure the component sits flush to preserve correct geometry. Installing a new cross member in place of a bent or worn one can restore centring and reduce vibrations that impact flight performance.
