Hirobo HI2511008 M3 x 69 Cross Brace for Helicopter Frames  [HI2511008]

Structural Cross Brace

This RC cross member is intended for general helicopter assemblies and acts as a structural connector that keeps components aligned during operation and maintenance. It provides a fixed datum for adjacent parts and helps maintain registration under load.

Fitting is straightforward: align the brace with the designated mounting holes, fasten with M3 screws that suit the M3 x 69 indication, and confirm correct seating with the rotor and drivetrain under normal preload. The M3 x 69 marking assists in verifying fastener length and hole spacing.

From a durability standpoint, the cross brace contributes to overall frame stiffness. Regular inspections for deformation or looseness and maintaining correct fastener security will reduce the chance of play or misalignment developing over time.
