SX Tail Blade Holder Hirobo HI0404542  [HI0404542]

SX tail blade mount

This RC-scale tail blade holder is intended for Hirobo SX-series rotorheads and is supplied as HI0404542. The part secures the tail blade to the tail rotor assembly and acts as a locating mount during blade swaps and routine workshop maintenance for Eagle, Freya and EX airframes.

Fitting is straightforward for modelers familiar with small helicopter work: access the tail hub or remove the tail rotor per your airframe service steps, fit the holder to align the blade shaft, and tighten fasteners to the service torque recommended for your model. Use the correct hex driver and ensure the tail blade can sweep freely with the tail servo at neutral before powering up.

During setup the holder keeps blade position consistent and reduces lateral play at the blade root, aiding predictable tail response. After installation confirm blade tracking and tail pitch geometry, then perform a low hover check to verify control authority prior to full-power flights.
