Hirobo HI0304110 blade holder for Embla SZM2 rotor assembly  [HI0304110]

Embla SZM2 blade holder

This blade holder is an RC-scale spare part for the Embla SZM2 rotor system, listed as Hirobo HI0304110. It serves as the rotor blade clamp interface, retaining the pitch blade root to the rotor hub on model helicopters built around the Embla SZM2 platform.

Designed as a direct replacement component, the holder's role is mechanical: secure blade roots, maintain pitch alignment, and provide a repeatable mounting surface during setup and maintenance. When diagnosing blade play or unusual vibration, checking this part for wear or damage is a common troubleshooting step.

Installation notes: remove the main rotor assembly following your model's standard safety procedure, inspect mating surfaces and fasteners for wear, then install the holder ensuring correct orientation and torque on retaining screws to avoid pitch offset. Final checks should include blade tracking and a vibration check before flight.
