In addition to miniatures, special effects genius John Stears and his crew made a single, full-size X-wing for scenes in the Rebels' Yavin 4 base hangar; combined with cardboard cutouts and careful editing, the Rebels appear to have dozens of fighters. The production crew also made a full-size X-wing cockpit that was used for all actors; the astromech droid visible behind each actor was changed for each starfighter. Background noise pitch and tone also varied between X-wings to further differentiate the characters piloting them.
