The RX-93 is such a cool update to the original RX-78 design, just look at the mighty chin on that thing! This is a great kit, the box art alone is worth the price. As to the kit, the proportions are quite nice, which was quite unusual for 1/100 Bandai Gundam kits at the time. This is also one of the first kits with "color accurate" parts. While I don't care what color the parts are molded in, since I paint all of my kits (everyone should!), it's nice to have parts broken down by color, since it minimizes masking. There are, however, some problems with the kit. The shoulder articulation is minimal (no forward/backward rotation), the abdomen is just plain ugly, and some parts could use detailing. Built approximately 100 years ago, this is the first Gundam kit I heavily modified, and my first attempt at pre-shading with airbrush, and I'm quite pleased with the way it turned out.
Looking back at this build today, what seemed like major modifications are actually pretty minor, but I think there may be a tip or two of use. The build log is here, or just scroll down to the pretty pictures if you like.
