Hirobo HI2511011 Cross Member M3 x 70 for RC Helicopter Frames  [HI2511011]

Central cross member for scale helicopters

This Hirobo HI2511011 cross member is an RC-scale accessory intended for helicopter general parts and frame assemblies. The listed M3 x 70 designation identifies the fastener interface and length reference used where M3 hardware is required.

Functionally, this cross member serves as a structural tie between frame elements, helping to maintain alignment and resist torsion under load. In tuning and setup it contributes to consistent geometry between mounting points, which can affect flight stability on scale helicopter models.

Installation notes: use matching M3 bolts and compatible nuts or threaded inserts, verify hole alignment before final torque, and avoid over-tightening to prevent stripping or deforming surrounding components. If threadlocker is employed, choose a removable strength appropriate for hobby parts so future servicing remains possible.

Because the listing does not specify material or finish, confirm the product details with the seller or parts diagram when exact composition is required for weight or corrosion considerations.
