Hirobo HI2511014 Cross Member M3 x 30-S Frame Connector  [HI2511014]

Hirobo HI2511014 M3 x 30-S structural connector overview

The Hirobo HI2511014 cross member, designated M3 x 30-S, is an RC helicopter frame connector used to maintain precise alignment between plate sections. It acts as a transverse link to transfer concentrated loads between bolt points without affecting the core airframe geometry.

Fitting follows a simple routine for those familiar with M3 fasteners: place the cross member between the frame plates, check for any component interference, and secure with M3 screws or studs of correct length. Hardware inclusion is not guaranteed, so confirm screw length for your build before assembly.

As part of a tuned build, the cross member helps hold alignment under vibration and during dynamic maneuvers, supporting consistent actuator response. Inspect threads and attachment security after initial flights and during routine maintenance to ensure continued alignment integrity.
