Hirobo HI2511022 53mm M3 Cross Member Replacement Part  [HI2511022]

53mm M3 Cross Member Specification

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 requires basic tools: align the member, insert M3 fasteners, and tighten evenly to avoid twisting the frame. Inspect threads and mating surfaces before assembly, and replace any stripped hardware to maintain secure joints.

As part of tuning and upkeep, a straight, firmly mounted cross member helps control frame flex and vibration. Regularly inspect for bends and thread wear, and keep spare M3 screws and locking compound handy for quick field repairs.
