This hexagon cross member is an RC-scale replacement part listed under Hirobo helicopter general parts. The product name indicates an M3 thread interface and a 64mm length, which is used where a straight cross member element is required in a helicopter frame or related sub-assembly.
Use: the component serves as a structural link within the frame, helping to maintain alignment between mounting points and contributing to basic stiffness and geometry stability. It is intended for model helicopters and should be treated as a spare part for routine maintenance or minor repairs.
Installation notes: confirm the M3 thread fit and the 64mm dimension against the existing mounting points on your frame before fitting. Secure fasteners to the cross member with the appropriate M3 hardware and verify clearances with nearby components such as servos, motor mounts, and wiring harnesses to avoid interference.
Tuning role: swapping or replacing a cross member can affect how the frame distributes load and transmits vibration. Use this part when restoring original layout, correcting bent or damaged members, or when matching replacement geometry for alignment checks during setup.
