Hirobo HI2511015 M3 x 64 Hexagon Cross Member Replacement Part  [HI2511015]

Structural Strength and Longevity

This hexagon cross member is listed among Hirobo helicopter general parts as an RC-scale spare. The designation indicates an M3 threaded interface and a 64mm length, suitable where a straight cross member is required in a frame or sub-assembly.

Use: the piece provides a structural connection that preserves alignment between mounting points and contributes to the basic stiffness and geometry of the airframe. It is meant as a spare for model helicopters to support regular maintenance or minor repairs.

Installation notes: confirm M3 thread compatibility and the 64mm dimension against existing mounts before fitting. Fasten with appropriate M3 hardware and check for adequate clearance around servos, motor mounts, and wiring to avoid contact and wear.

Tuning role: while primarily a structural spare, replacing a compromised cross member can reduce transmitted vibration and help maintain designed load paths when restoring a model to service.
