TRANSFORMATION

Push the head down into the torso slightly, then open the chest panels to both sides.

Rotate the central nose section 180 degrees and stand it up, then close the chest back up.

The converters and wings need to be arranged and spread out as shown.
Looking at the example build, the direction the blue wings bend is reversed between the pre- and post-transformation states,
so I swapped the left and right blue wings.
(The manual does say you can arrange the blue wings however you like anyway.)

Remove the hands, attach the separate covers, then arrange them into a bird-foot shape as shown on the right.

Fold the legs into the shape shown above, then

open the canopy and rotate the cockpit 90 degrees — transformation complete.

This kit is the Premium Bandai online exclusive RRR 1/35 Billbine. It's an Aura Battler from the 1983 anime Aura Battler Dunbine, and the main unit from the latter half of the series.

First off, RRR(abbreviated R3) stands for Real Robot Revolution. It was an ambitious series that ran from 2006 to 2008, bringing 80s real robot mecha up to MG-level scale and quality. It didn't sell particularly well though, and the line was effectively discontinued after just four releases. Then, 17 years later, R3 has suddenly made a comeback as an online exclusive.

Like the original RRR kits, this one comes in a large MG-scale size, but with almost no inner frame it feels closer to an RE/100. That means the parts are nice and chunky and there aren't too many of them, so assembly is pretty relaxed and easy. The complex color layout is also well handled through color separation, so even a straight build looks great. It's got solid articulation and strong joint strength throughout, giving the whole kit a reassuringly stable feel.

The transformation into Wing Caliber form isn't all that complicated either — basically just open up the chest and fold the limbs into position. The overall shape holds together well after transformation, so it looks stable even when mounted on a stand. The one weak point is the poseable Aura Cannons on the back — their joints feel noticeably looser compared to everything else. All the other joints and moving parts are solid, but the Aura Cannons keep drifting out of position.

For weapons, you get an Aura Sword, an Aura Sword Rifle, and four lead wires for the short claws. The Aura Sword Rifle can be folded in half and fitted with beam parts to turn it into a sword, and there are also support parts that let you mount it next to the converter on the back.

Aside from those loose Aura Cannons, this is a mecha model kit that's hard to fault overall. The construction does feel subtly old-school in places — especially the huge ball joints used for the hip joints, which you don't really see much anymore. That said, old-school joint design is forgivable when the joints are actually sturdy. If you're an old-school fan with fond memories of Dunbine, or if the unique design just speaks to you, this kit is well worth the ¥5500 investment. :-)
