Hirobo HI2511021 Cross Brace M3 x 105  [HI2511021]

Frame alignment cross member suited to Hirobo assemblies

This item is a general RC helicopter cross member used to connect structural points and preserve positional stability. The M3 x 105 label denotes the compatible fastener pitch and the part length, matching locations where M3 hardware is specified.

Use the cross member to keep subframes and mounting points in line during setup or after repairs; maintaining straightness helps reduce undue wear on bearings and transmission components. It is practical as a replacement piece when restoring drivetrain or rotor geometry.

Installation advice: use proper M3 screws to the factory mounting holes, verify that mating threads are undamaged, and confirm static alignment before flight testing. Take care not to over-torque and re-inspect tightness following initial bench checks.
