• a motor assembly mechanically grounded to the center section;
• left and right oppositely handed leadscrews each having a rotational axis, the left leadscrew being coupled to the motor assembly and to the left leadscrew receiver, the right leadscrew being coupled to the motor assembly and to the right leadscrew receiver;
• wherein operation of the motor is capable of moving the wing between a deployed position in which a lateral extremity thereof is outboard of the outboard edge and a stored position in which the lateral extremity is inboard of its deployed position;
• and
• wherein operation of the motor in a first rotational direction moves each wing in unison in a laterally outboard direction and operation of the motor in a second rotational direction moves each wing in unison in a laterally inboard direction.
