Une ouverture (101) destinée à recevoir le gouvernail de direction (200) est formée dans l'élément de fixation (100) ; le premier élément de montage (310) est pré-encastré dans l'élément de fixation (100), une première extrémité du premier élément de montage (310) est fixée au moteur de direction (330), et sa seconde extrémité est dotée d'une première partie (314) faisant saillie à partir de l'ouverture (101) ; une première extrémité de l'élément de transmission (340) est en liaison de transmission avec le moteur de direction (330) ; une partie centrale du raccord de moteur de direction (320) est pré-encastrée dans le gouvernail de direction (200), une première extrémité du raccord de moteur de direction (320) est reliée à une seconde extrémité de l'élément de transmission (340), et sa seconde extrémité est reliée rotative à la première partie (314). Le véhicule aérien sans pilote à aile fixe et son empennage peuvent réduire la résistance au vent, améliorant ainsi l'efficacité de vol et la vitesse de vol.
