The RG Zeta Gundam that so many fans have been waiting for has finally been released. Before it came out, there was a lot of debate about whether it would be able to transform or not — but RG is RG!! Despite being in the small 1/144 scale, it delivers a fully self-contained transformation gimmick along with a full-body inner frame. Given how complex the transformation gimmick is, you'd expect the engineering to have been incredibly difficult — and after actually building it, you really do get a sense of the craftsmanship and hard work that Bandai's development team poured into every single detail. ^^
Setting aside the transformation gimmick for a moment and looking at the overall kit composition, all the hallmarks of RG are very much alive and well here. The white and gray base color combination, near-perfect color separation, the full-body inner frame provided as a single integrated piece — it's all faithful to the RG fundamentals. On top of that, there's a beam saber storage gimmick, cockpit hatch opening, forearm grenade cover opening, and various articulation gimmicks for the weapons — a wide range of features that are on par with or even beyond MG level. One particularly interesting touch is that both rear skirts can move independently, which is actually kind of amazing when you think about it — no Zeta Gundam plastic model has ever had that feature before. It doesn't really help with leg articulation, but it's nice that they paid attention to even these little details. And as a bonus, you even get a shield grenade launcher pack that wasn't included in either the MG or PG.
Articulation is decent as you'd expect from an RG, but... the leg transformation gimmick does make it hard to get natural-looking leg poses. In particular, when standing on a flat surface, the range of poses you can pull off is very limited — you really need a stand to get it looking halfway decent. Even then, the hip joints don't swing side-to-side very well, so posing it in the air isn't super easy either. The only consolation is that it's a slight improvement over the MG Zeta v2.0. Either way, the RG is no different in that you really shouldn't expect great articulation from a Zeta Gundam. ^^;
The most important feature of the Zeta Gundam is of course its signature Waverider transformation gimmick. Unlike the HGUC, the RG Zeta Gundam is capable of 100% self-transformation without any parts swapping. The overall transformation process isn't drastically different from before, but many of the finer gimmick details have changed quite a bit compared to the MG v2.0 — more precisely, they've been refined into the most evolved form yet.
The biggest difference is definitely the hip joint expansion gimmick. They've done away with the 90-degree rotating/locking hip plate used in the MG v2.0 and PG Zeta, and boldly switched to a rotating plate system where a large hip plate at the rear rotates 180 degrees in a double-layered fashion. On top of that, lowering the rear skirt locks this hip plate in place, while raising it locks the upper and lower body in a straight line — a so-called "killing two birds with one stone"gimmick — which has greatly improved the stability of the hip joint and body in both MS mode and Waverider mode. Also, the side torso compression/expansion gimmick that was the biggest headache in the MG v2.0 has been implemented in a much simpler way, making transformation easier and the fit more secure, which I really appreciate. Folding the head antenna and tucking the head in and out is also no easy feat, but the RG Zeta handles it smoothly without any major issues.
The S-bend knee gimmick no longer requires the complicated extend-and-compress routine like the MG v2.0 — you just bend it twice in quick succession and all the various knee gimmicks link together and fall into place automatically. On top of that, a rotating lever mechanism automatically adjusts the ankle length and rear vernier covers as you go, extending and retracting on their own — which makes transforming the legs incredibly easy. It's truly a triumph of gimmick engineering, and the improvement in ease of use and handling is massive.
That said, the section where you raise the upper body and align it with the backplate has more moving parts than necessary, which makes it a bit tricky to move and lock into place. In particular, getting the chest armor to sit properly in MS mode is somewhat ambiguous, making it a little difficult to nail down a clean proportion. If you look at the chest area in the MS mode photos above, you might notice something feels a bit off — and when you actually handle it, it really isn't easy to get it to lock in as nicely as you'd hope. T_T Every time you touch the chest to adjust something, it keeps shifting out of place...
In any case, the transformation gimmick alone is packed with ideas that surpass the old MG and PG, and the fact that they managed to cram a full inner frame and transformation gimmick into such a small-scale kit is genuinely awe-inspiring. And since locking pins are provided just like on the MG/PG, the stability after transforming into Waverider mode is pretty solid too. Apparently this is the RG kit that Bandai spent the longest time developing — and after building it, you can totally see why.
There are a few things to nitpick though. The transformation process has come a long way, but it's still not easy. T_T In particular, rotating the wings and locking them into place still has the legs getting in the way, so you have to carefully line everything up just right for it all to click together. There's also the issue of the chest armor being tricky to lock in cleanly in MS mode, and the leg articulation still leaving something to be desired due to the transformation gimmick. Separately from that, some parts don't hold together well with snap-fit alone — things like the side skirt connection points, the clear parts on the beam rifle, and the wing-to-body connection points in Waverider mode — so for some of these, you'd probably be better off just gluing them for your own sanity. And while it's probably a cost issue, the omission of the Hyper Mega Launcher is a bit of a shame too.
All in all, this is a kit that leaves you feeling very satisfied — just being able to build a kit this small with such an incredibly precise gimmick packed inside is enough to move you. In terms of gimmick engineering, this was probably the greatest challenge Bandai's developers have ever faced, and thanks to the long and thorough development process, the result is a masterpiece to match. The few shortcomings feel minor given just how polished the overall kit is — if you're a Universal Century fan, this is an absolute must-buy, no question. And I have a feeling we won't see gimmick engineering this painstakingly crafted again for a long time. A true gem of a kit. :-)
