Hirobo HI2511008 Cross Member M3 x 69 for RC Helicopter Frame  [HI2511008]

Helicopter Frame Cross Member

This RC-scale cross member is supplied as Hirobo HI2511008 and serves as a structural element within helicopter frames. It locates adjacent assemblies and holds components in alignment during normal operation and routine maintenance.

Installation is mechanical: align the cross member with the corresponding mounting holes, secure it with M3 fasteners that match the M3 x 69 specification, and verify alignment under normal rotor and drivetrain preload. The M3 x 69 notation guides fastener selection and hole spacing checks.

In tuning and fault finding, the cross member primarily influences chassis rigidity and part registration rather than flight electronics. When diagnosing vibration or misalignment, inspect the cross member seating and fastener torque as part of the chassis check routine.
