Replacement Elevator Shaft for EX Range - Hirobo HI0404143  [HI0404143]

Replacement Elevator Shaft — EX Range

This elevator shaft set is designed as an RC-scale replacement for Hirobo rotorcraft models where it is listed as a common part for Eagle, Freya, EX and SX lines. It supplies the rotating link between servo output and the elevator assembly and is supplied as a service item rather than an aftermarket performance upgrade.

Fitment notes: confirm shaft compatibility with existing bearings and linkage arms, inspect 走珠軸承 for wear before refitting, secure with the correct 六角螺絲 and follow manufacturer torque guidance. When installing the shaft, align the elevator linkage carefully to avoid binding and to preserve neutral hover trim.

Effect on flight feel: the shaft sets part of the control geometry and responsiveness; replace it if bent or worn, or if you detect play in the control chain. Post-install, run a static control sweep and a low hover test to make sure travel is smooth and trim remains stable.
