not much, the basic "hull" is together and have eliminated seams, now I have to try to make up a gondola pattern (the kit is waaay off and I chopped off the top half), and will use some really thin plastic to cut new windows and wrap it. I also have to probably redo the engines, they suck on the kit. The props are molded in some weird rubbery stuff, no way to file thin, so i might do a quick-and-dirty "in action" technique, and use clear plastic circles, slightly frosted, to show the motors running...
