Hirobo HI0404143 EX elevator shaft set  [HI0404143]

Elevator shaft set for EX series

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 supplies the rotating linkage element that connects control outputs to the elevator mechanism, and is intended as a direct service item 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 manufacturer torque practices. When replacing the shaft, verify alignment of the elevator linkage to avoid binding and to maintain neutral pitch at hover.

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