Hey Acid, what do you think of the RG series? I have a Zaku 2, partially built, but I had to stopped because I clipped one of the leg exhaust pipes by accident.
i also have the RX-78, but not built yet.
I know you didn't ask me, but I personally love RGs, with a couple caveats.
One, I don't think inexperienced modelers should really build them. They tend to be quite difficult and fragile builds. Two, it's a series where the good kits are good, but the bad ones are really problematic. Anything pre-Gundam MK-II is extra fragile. The Zeta has fragility issues due to the transformation, but is other wise good and the SEED Destiny series of them all kind of suck in their own ways. So, given that I'd say.
Buy: GP-01/FB, Gundam MK II, Aile Strike, Exia, Freedom, Z'gok, Wing Zero EW
Maybe get, but know it has problems: Zeta
Avoid (or just go in knowing they are really problematic): Zaku-II, RX-78, Destiny, Strike Freedom, Infinite Justice.
I've actually never built an RG before. I prefer to build Master Grade kits mostly and HG sometimes. The RG stuff looks really good at least. I've heard that the quality of the kits can vary a lot. Like, the RX-78 is supposed to be good while I've heard the Zeta is terrible. The sheer amount of tiny pieces seems like it would make them fairly hard to build. Was thinking of picking up a Wing Zero Custom to try the line out though.
I actually would say that the Zeta is a real cool little kit and worth getting. The RX-78 has fragility issues that could have been avoided, but are a problem because it's an early attempt. The Zeta knows exactly what it's going for and achieves it. The transformation is so impressive. The fragility can be avoided if you know what you're doing. The problems are sort of necessities for that kit to be what it was attempting.
As for Wing Zero, I'd say buy it immediately. I adore that kit. It's one of the best, most stable of the whole line and looks amazing in person. It's up there with the GP-01 as my favorite RG.
