EX Elevator Shaft Set for Eagle/Freya/SX - Hirobo HI0404143  [HI0404143]

EX Series Elevator Shaft Replacement

This elevator shaft set is an RC-scale replacement part intended for use in Hirobo rotorcraft lines listed as common parts for Eagle, Freya, EX and SX models. The set provides the rotating linkage element that connects servo output to the elevator mechanism and is supplied as a service replacement rather than a performance upgrade.

Installation notes: confirm fit with existing bearings and linkage arms, inspect 走珠軸承 for wear before reassembly, secure fasteners with the correct 六角螺絲 and tighten to the manufacturer's torque recommendations. When fitting the new shaft, ensure the elevator linkage is aligned to prevent binding and to maintain neutral pitch at hover.

Tuning role: this shaft determines mechanical geometry and responsiveness of the elevator linkage; replace it if bent, worn, or if free play appears in the control path. After installation, carry out a static control check followed by a low-altitude hover test to confirm smooth travel and expected trim behavior.
