Hirobo HI2511014 Cross Member M3 x 30-S Structural Brace  [HI2511014]

Rigid M3 x 30-S cross member for RC helicopters

This Hirobo cross member HI2511014 is an RC-scale helicopter structural component marked M3 x 30-S. It functions as a transverse brace to lock frame plates in alignment and to transfer localized loads between mounting points without altering the main airframe geometry.

Installation is simple for builders familiar with M3 fasteners: position the cross member between the mating frame plates, check clearance for adjacent parts, and secure with M3 screws or studs of the proper length. Do not assume hardware is included; verify screw length against your stack height before final assembly.

When fitted correctly, the cross member reduces flex under vibration and during maneuvers, aiding servo and rotor repeatability. Inspect thread condition and fastener security after initial flights and periodically thereafter to maintain alignment performance.
