SX Tail Blade Holder HI0404542 Compatible with Hirobo Series  [HI0404542]

Tail blade location for SX rotorheads

This HI0404542 tail blade holder fits Hirobo SX-series rotorheads and is supplied as a precision locating part. It clamps the tail blade into the tail rotor assembly and serves as the reference point when swapping blades or carrying out routine maintenance on Eagle, Freya and EX models.

Fitting is intended for those comfortable with small helicopter servicing: gain access to the tail hub or remove the tail rotor as needed, place the holder to align the blade shaft, and secure the fixings to the recommended torque. Use the correct hex bit and confirm the blade clears its sweep with the tail servo at neutral before any flight tests.

In trimming and tuning, the holder helps reduce lateral play at the blade root to preserve consistent tail response. After installation verify tracking and tail pitch linkages, then run a controlled ground hover to confirm handling before extending throttle.
