The Hirobo HI0404634 stay is an RC replacement part that secures standard servos within Eagle-series airframes and associated Freya, EX, and SX models. The supplied H=17mm offset produces a fixed mounting height that aids correct servo horn and linkage alignment.
Intended use: this stay holds the servo flange steady to limit flex and retain control geometry during flight and setup. Fit it where the factory mounting requires a 17mm spacer to achieve neutral link angles or to clear adjacent structures.
Practical advice: check servo flange hole spacing against the stay before final assembly, ensure servo spline and link align correctly, and use threadlocker compatible with aluminium if vibration is a concern. Fine-tune horn placement and clevis length to prevent binding and secure predictable control response.
