Hirobo HI2511022 Cross Member M3 x 53 Replacement  [HI2511022]

Specification: M3 x 53 Cross Member

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.

To install, align the member with the frame mounts, use appropriate-length M3 fasteners, and tighten carefully to maintain alignment. Avoid excessive torque which can strip threads; confirm that the 53mm measurement matches the mounting geometry prior to final assembly.

For ongoing service, check the part for straightness and thread wear after hard landings or crashes. Keeping spare M3 nuts and screws and a small tube of removable thread-lock will simplify future repairs and preserve secure joints.
