Great kit... but problematic build
It's an awesome kit... When it's built correctly. And it's not so easy.
There are some leftovers parts from the "dark" past of RG : some junctions are made in one piece of soft plastic (like the complete inner frame from the older kit). These pieces are really not good, mostly for a huge kit like this.
And there are the junctions for the arms : three pieces of (hard) plastic that must be inserted into each other and, when it's firmly done, you must turn one of them. You must be careful and push the piece all the way to the end before turning it, otherwise... "crack" and it's the end. But with patience and being warned, it's okay.
The final product is a great RG kit...
But i wish Bandai throw away the soft plastic inner frame parts... Please !
