Just wanted to chime in with some comments about the VF-31 model kit (Hayate's colors). I don't consider myself a master builder, though I've built dozens of MG Gundams and a handful of Hasegawa Valkyries. The extent of my "customization" skill is panel-lining and small amounts of painting. This is my first Bandai transforming Macross model kit.
Building this is REALLY FUN! I'm actually AMAZED that the VF-31 kit seems to have half as many parts as the typical MG Gundam kit, yet the VF-31 transforms. Voodoo, I tell you, voodoo!
Prior to building, I did my research. I've read reviews that stated the Battroid mode doesn't hold together, parts break during transformation, etc. So I'm building very cautiously. Each time I put together a moving part, I "practice" transforming by just moving that one part in the way it needs to go to transform. In doing so, I've found several spots where the parts clearances are quite small (or nonexistent), and I've sanded them down so that the clearances are just right. It's pretty clear that, if I were to transform the kit as-is without any sanding, it's exceedingly obvious how transforming the toy would break it. I've also found some parts that come apart (in unintended ways) while moving them around (such as the various pieces that comprise a solid section of the wing), so I use some plastic cement here and there. Never on moving parts.
Anywhoo, I'm only half done with the kit so far, and I'm taking it slowly but methodically, testing the parts clearances one by one as I add them.
And, did I mention building this is actually FUN? I do appreciate the details on an MG Gundam, but I've always found it tedious to build the inner skeleton, then some inner machinery, and then cover it all up with outer armor. For better or worse, the VF-31 kit doesn't have that layer of detail. The parts count is basically the bare minimum for just the outer appearance of the jet and/or robot, which suits me just fine.
Building this kit is so fun, I ordered another VF-31 (Messer's colors) because, well, I want to build another one.
At first, buying the model kit was just a cheap substitute because I can't afford the DX Chogokin VF-31. However, the model kit is so well engineered (after some sanding and cementing), I find that I don't even think of the model kit as a substitute anymore.
