This RC-scale seesaw linkage is a direct replacement for the Hirobo Eagle Freya tail assembly and provides the pivoting interface between tail pitch input and the tail mixing mechanism. It converts servo motion into precise tail blade pitch changes for stable yaw control.
Compatibility centers on Eagle Freya series parts under Hirobo; always match the HI0414105 part number with your helicopter parts list before purchase. Fitting the part needs access to the tail hub and common RC tools, and it mates with standard control rods and ball links used on scale electric helicopters.
Tail setup is affected by this linkage because it defines mechanical leverage and neutral position. When tuning, check linkage free-play, centring and servo travel, and ensure fasteners are torqued correctly to reduce slop and keep predictable tracking during hover and yaw moves.
