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

Cross member M3 x 30-S for RC Helicopters

This Hirobo cross member HI2511014 is an RC-scale helicopter general part labeled M3 x 30-S intended as a structural connector within model helicopter frames. It functions as a transverse brace to keep frame sections aligned and to transfer localized loads between mounting points without altering primary airframe geometry.

Installation is straightforward for builders familiar with M3 fasteners: position the cross member between the mating frame plates, verify clearance for adjacent components, and secure using appropriately sized M3 screws or studs. Do not assume included hardware; confirm screw length to match your stack height before assembly.

In tuning contexts this cross member helps maintain consistent alignment under vibration and during flight maneuvers, which can aid servo and rotor system repeatability. Routine inspection for thread wear and secure fastening is advised after initial flights to ensure continued alignment performance.
