Hirobo HI2511022 M3x53 Cross Member for Helicopter Frames  [HI2511022]

M3 x 53mm Cross Brace Details

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.

Fitting is simple for anyone with basic RC toolkit skills: clean the threads, position the brace, then secure with M3 screws while avoiding excess torque. When swapping out an old member, ensure that frame holes line up and that the 53mm length corresponds to the mounting geometry before final clamping.

Routine checks of thread condition and straightness will keep the frame stable and reduce vibration. Carry spare M3 hardware and a small amount of thread-lock for service intervals or rapid part changes.
