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

Hirobo HI0404634 servo mount for Eagle family

This Hirobo HI0404634 servo mount stay is a precision replacement designed to locate and secure standard servos in Eagle-series helicopters and compatible Freya, EX, and SX airframes. The H=17mm offset gives a fixed mounting height that aids correct servo horn geometry and linkage alignment.

Role in the airframe: the stay stabilises the servo flange to reduce flex and preserve control surface geometry during flight and setup. Fit it where the original mounting requires a 17mm spacer to achieve neutral link angles or to clear adjacent frames and moving parts.

Installation tips: measure servo flange hole spacing against the stay before final fitting, ensure servo spline and linkage are aligned, and use adhesives or threadlockers approved for aluminium surfaces where needed. Set the servo horn and clevis lengths to minimise binding and to ensure smooth, repeatable travel.
