Hirobo HI2511011 Structural Cross Member M3 x 70  [HI2511011]

Structural tie bar for helicopter frames

This Hirobo HI2511011 cross member functions as an accessory for helicopter frame assemblies and general parts. The M3 x 70 notation refers to the metric M3 fastener size and a 70 mm length reference applicable where M3 bolts are used.

Its role is to join frame elements so alignment is preserved and torsional loads are better resisted. Proper installation helps keep mounting points in consistent positions, which can affect how the model flies under load.

Fitting advice: use the correct M3 bolts with matching nuts or inserts, check alignment of holes before applying final torque, and avoid over-tightening to protect threads and surrounding parts. If threadlocker is required, choose a removable grade suited to hobby maintenance.

Because the listing lacks material or finish details, verify specifics with the seller or parts diagram when composition matters for weight or corrosion resistance.
