1/72 VF-1S and VF-1A

The transforming VF-1A & VF-1S kits by Bandai. Rather interesting build, however transformation ruined the articulation of the kit - GERWALK mode has weight issues and BATTROID mode will keep sliding and falling apart when you try to move limbs. Making it stand is possible, but it's a tough job. I won't say the design is bad — it has a great design with a lot of gimmicks to keep the transformation and proportions true to original, but there's only so much you can do with the plastic model of that size. However the normal hands are a disaster. They have very limited articulation and fingers are fixed in the palm in such a manner, that if the palm parts are slightly spread, the fingers can and will fall out. Making VF-1 hold it's rifle properly with index finger on a trigger is a nightmare. They could have gone with a swappable hand that does that and looks good, but just didn't, although kit comes with an extra swappable set of straight  "salute" hands.

Model comes with the stickers and decals, making it a tough choice between the two - stickers are not your usual film-based, but rather thick insulating-tape-like material (if you built the 2012 MG Nu ver.Ka you've seen this kind of stickers - the ones used to add more color variation to the kit). With transforming parts that have tight fitting (as is usual with Bandai kits) this means that you'll have some stickers dislodged by moving parts (e.g. black lines on the side of the cockpit towards the engines or the top of the wings). Decals will very likely be scraped off by these parts, just a bit later.
