Just started on the 1/48 Kinetic Su-33. I was really excited about building this thing because I'd heard so many good things about it. I have to say that so far, and it's still early in the kit, I am not impressed. I started with the seat as you see here. The instructions are rather vague and unless you are familiar with the intricacies of the real thing, you'll have difficulty figuring out where some parts are supposed to go. The fit so far is terrible. The seat back, for instance is a separate, curved piece, yet the part it's supposed to rest against is flat causing it to rock back side to side leaving big gaps along its sides. I had to take a bone bur and add curvature to the horizontal piece on the seat frame. The seat bottom is too thick and the bottom front edge has to be thinned in order for it to fit in the frame. There is a lot of flash and the plastic feels a bit "waxy". The CAD illustrations are really terrible and as I mentioned, parts location can be vague. So far, I've spent 3 hours on the seat and it looks terrible.
