Eagle/Freya 17mm Servo Mount Stay HI0404634 — Hirobo  [HI0404634]

Precision 17mm mounting stay

The Hirobo HI0404634 mount stay is made to secure standard servos inside Eagle-series models and the related Freya, EX, and SX airframes. The 17mm height offset ensures predictable horn positions and helps maintain correct linkage angles under load.

Function: this stay keeps the servo flange stable to cut down on flex and preserve trim while tuning and flying. Use it where the original mounts need a spacer to achieve neutral link geometry or to avoid contact with the frame.

Workshop advice: double-check flange hole spacing before fitting, align the servo spline with the control linkage, and select adhesives or threadlocker compatible with aluminium if required. Fine-tune horn placement and clevis settings to prevent binding and to secure crisp control inputs.
