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

Tail holder role 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 serves to locate the tail shaft, keep alignment with the tail rotor drive, and provide a mounting surface for related tail linkage components. When replacing this part, confirm the 19mm diameter match to the existing shaft and check clearance to surrounding frames and bearings to preserve free rotation and avoid binding.

Installation notes: verify fastener lengths and thread engagement used on your helicopter, use thread-locking compound where model practice calls for 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.
