I built this kit (it's a Houjian-class missile boat) last year with a LOT of extra scratchbuilt detailing (mostly styrene stock and metal wire). Here's a photo:
Unfortunately it's painted in the wrong shade of grey (the paint I used is more like US Haze Gray, it should be a more neutral, less bluish shade) but still looks good IMHO. For reference material I used various photos of the ship found on the Internet (search for "Houjian missile boat" on Google)
This kit is easily the worst of Trumpeter's range of large-scale Chinese ships - as you say, it's basically a motorised toy. Their 1/200 Chinese ships are vastly better, although still not as good as their more recent 1/200 Sovremenny.
