Hirobo HI2511008 M3 x 69 Helicopter Cross Member Replacement  [HI2511008]

Airframe Cross Member Overview

This RC cross member is used within helicopter frames to align and secure components, maintaining registration during normal operation and servicing. It provides a stable structural point for neighbouring assemblies.

Fitting procedure is mechanical: position the cross member to the mounting holes, secure with M3 fasteners that correspond to the M3 x 69 specification, and verify alignment while the rotor and drivetrain are under normal preload. Use the M3 x 69 reference to confirm fastener length and hole spacing before final torque.

When checking compatibility and performance, remember the cross member influences frame stiffness rather than electronic behaviour. After installation, if vibration or runout is observed, recheck seating and fastener torque as part of the inspection routine.
