The Yamato Queadluun-Rau was designed using Computer Aided Design (CAD), as was Yamato's 1/48 series of VF-1 toy and it shows in the crispness and symmetry of the design.
The Queadluun-Rau toy features a number of gimmicks such as opening missile launchers, and opening cockpit, and the aforementioned removable pilot, swappable thigh missile launchers, rotating hands and wrist guns.
The cockpit is covered by the head armor and left and right shoulder covers. To open the head armor, simply rotate it up and to the rear, making sure to position the communications antenna on the head in the forward position. You will find that one you lift the head to near vertical, it can then be pushed a few more millimeters to the rear, allowing it to tilt a few more degrees nearer to vertical.
To correctly open the left and right shoulder armor, first pull then towards you (they are connected to horizontal sliding rods, which slide into the back of the toy). One you have pulled the shoulder covers forward towards you a few millimeters, simply rotate them up and to the rear. You will then see that the shoulder covers have a separate hinged inner covers attached to the inside of the outer shoulder armor, which can be hinged downward if desired to create a different 'open cockpit' pose. The monitor screen directly in front of the pilot can also be hinged downward. The cockpit of the interior is also nicely detailed, with some of the instrument panels being painted. However, the cockpit seems to be sculpted to more resemble the mechanical style TV style cockpit rather than the more organic looking DYRL style.
