I'm back. It is Chinese New Year school breaks. So, i'm home and i get to settle a couple of my unfinished model kit. Yay ^^. Anyway, as soon as i'm home, i just walk into my room, sat on the chair and begin the assembling process.
Inner Frame
This inner frame is so far the best among all RGs. It is very similar to its PG cousin. So yea , piston and other mechanical stuff can be found in joint ^^
