Rotor Blade Clamp for SCEADU FZ-3 HI0412103, Hirobo  [HI0412103]

Part overview and purpose

The Hirobo HI0412103 rotor head blade holder is an RC replacement component made to fit SCEADU FZ-3 rotor assemblies. It functions as the blade clamp interface that holds the main rotor blades at the rotor head and is intended for hobby maintenance, spare replacement, and straightforward alignment adjustments.

Installation guidance: check the rotor head mating surfaces and blade root for wear before installation, align both blade holders carefully to preserve symmetry, and tighten mounting screws a little at a time while verifying blade pitch and freeplay. Treat this item as a direct replacement-style spare for the listed SCEADU FZ-3 models.

Effect on setup: correct installation of the holder ensures reliable blade seating, helps keep rotor tracking consistent, and supports vibration control when used with balancing procedures. Include this check in your normal pre-flight inspection routine.
