Hirobo HI2511022 Cross Member M3 x 53mm Structural Support  [HI2511022]

Hirobo M3 x 53 Cross Support

This Hirobo cross member labeled HI2511022 is an RC-scale helicopter structural component specified as M3 x 53. It serves as a short cross-support piece used in general helicopter assemblies where a threaded M3 connection and a 53mm reach are required. The part is intended for repair, replacement, or rebuild tasks on Hirobo helicopter models that use generic cross-member mounting points.

Installation is straightforward for hobbyists familiar with basic RC assembly: secure the component using M3 fasteners, ensure threads are clean, and avoid over-torquing to prevent stripping. When replacing an existing cross member, check alignment of adjoining frames and confirm that the 53mm span matches the mounting geometry before final tightening.

In tuning and maintenance, this cross member helps maintain frame rigidity and alignment. Regular inspection for thread wear, straightness, and secure fastening will reduce vibration transfer and aid predictable flight characteristics. Keep spare M3 nuts and thread-lock compound on hand if you perform routine maintenance or frequent swaps.
