Hirobo HI0404634 — 17mm Servo Mount Stay for Eagle/Freya/EX/SX Helicopters  [HI0404634]

Mounting stay designed for alignment and tuning

The Hirobo HI0404634 servo mount stay positions and secures standard servos in Eagle-family helicopters and compatible Freya, EX, and SX airframes. Its H=17mm offset gives a repeatable mounting plane that simplifies achieving correct linkage and horn geometry.

Purpose: by stabilising the servo flange, the stay reduces unwanted flex and helps keep control linkages true during setup and flight. Install it where a 17mm spacer is necessary to get neutral link angles or to clear nearby structure.

Setup pointers: confirm your servo flange hole pattern matches the stay before committing, align the servo output spline with the linkage path, and pick adhesives or threadlockers safe for aluminium. Adjust horn position and clevis length carefully to avoid binding and to tune the control throw.
