Hirobo HI0404553 Root End for Eagle/Freya/EX/SX Helicopters - Tail Linkage Replacement Part  [HI0404553]

Part role and fitment

This Hirobo root end is an RC-scale replacement component listed as HI0404553 and intended for common helicopter service on Eagle, Freya, EX and SX platforms. It serves as a terminal connection in tail linkage assemblies where compact, serviceable joints are required for routine maintenance and repair.

Fitment is described as common parts for Eagle/Freya/EX/SX models, so confirm part codes on your airframe before ordering. The item is supplied as a single replacement piece and is intended to restore proper linkage geometry when an original root end shows wear or play.

Installation and tuning notes: remove the damaged root end from the tail linkage, inspect adjoining pushrods and bearings for wear, fit the replacement ensuring correct orientation and free movement, then check tail pitch and yaw response at low throttle before full flight. Minor trim adjustments may be required after replacement to re-establish neutral linkage alignment.
