Hirobo HI0404471 Tail Holder 19mm 60-BL Replacement  [HI0404471]

Tail holder: purpose and fitment

This RC-scale tail holder is a replacement-level component identified as Hirobo HI0404471 and marked 60-BL, configured for 19mm tail shaft fitment. It is supplied as a common spare for Hirobo models in the Eagle, Freya, EX and SX families and functions as the mechanical support around the tail shaft and tail rotor assembly.

In practical use the part locates the tail shaft, maintains alignment with the tail rotor drive, and provides a mounting surface for related tail linkage components. When fitting this item, confirm the 19mm diameter matches your existing shaft and inspect clearance to nearby frames and bearings to ensure free rotation and prevent binding.

Installation notes: verify fastener lengths and thread engagement for your helicopter, apply thread-locking compound where model practice requires it, and re-check tail tracking and vibration after installation. The 60-BL identifier is the manufacturer part code for this variant and should be matched when sourcing replacements.
