RC Helicopter Cross Member M3 x 70 - Hirobo HI2511011  [HI2511011]

Frame cross brace for RC helicopters

This Hirobo HI2511011 cross member is supplied as a general-purpose component for helicopter frame assemblies. The M3 x 70 marking denotes the metric fastener size and the 70 mm length reference used with M3 hardware.

As a structural element it links frame sections to preserve alignment and reduce torsional movement under load. Maintaining correct geometry between mounting points helps support stable flight behavior on scale helicopters.

Installation guidance: fit matching M3 bolts with appropriate nuts or threaded inserts, confirm hole and bolt alignment before final tightening, and take care not to overtighten which can damage hobby-grade threads. When using threadlocker, pick a removable grade to allow later servicing.

Note that material and finish are not specified in the listing; check with the seller or refer to the parts diagram when exact composition is important for weight or corrosion performance.
