Bill;
The Dragon SdKfz 265 3-in-1 kit. Good choice, IMO!
The 3-in-1 ref's the fact that you can build "versions" with and without applique armor on the front and glacis and cupola - and you can also do frame antenna or not. So you do get a crack at at least 3 versions - but wait - there's sort of more... you can of course do vehicles with or without the "after-market" add-on brace across the rear, and there are a couple of cupola choices (and a little scratch-work can actually take this kit back to an earlier production - if you want to build the hatches on top sans the cupola.
I'm just right now wrapping up one of these bad puppies - I did the applique armor as seen on one in N. Africa - my wrestle is that some with applique armor show up in the DAK, some in Russia (no, none of this version in France, 1940) - I like the add-on armor look, but also want to have the frame antenna (apparently a fairly rare and earlier feature - maybe more appropriate to France 1940 and without the add-on armor...) - and vehicles in Russia sported a variety of boxes and add-ons behind the top "carapace". And also featured quite a bit of dressing and load. So I have not finalized my paint scheme yet...
Anyway. Kit builds very nicely. I did find that the idlers, while much better than in the previous -265 kit, still need work. It is pretty easy to shave off some inside the rims of the 2 halves so as to better get that thin look. Likewise, the framing inside the wheels should ideally be thinned down a bit - the kit part is a little chunky. But easy to fix up with the little Exacto... The MG mount will frustrate you. (It does not offer positioning). The road wheels are pretty nice - but those in the Pz. IA and IB SmartKits with the little brass rings to create the realistic flange are much better looking. If you can add these, they do make a nice upgrade. I suggest "Make those vision flaps open"- nice look and nicely detailed bits. This kit begs for an interior... both the cupola hatch and side-hatch offer a good look inside the shell.
About the tracks... The links are TINY. But they go together very nicely, and will really look the part. Unless you are pouring cement like some pour syrup on hotcakes, you'll not likely have any "fill problem" - specially if you use very thin cement. The tracks are the same as on the Flakpanzer IA kit (which I have done OOTB), and they are gems. You won't save any work doing Fruils, and definitely not money - but there are lots of fans of those and they do look nice. For my money and time, the kit tracks worked fine.
Enjoy! I look forward to seeing your build come up - I've always liked this vehicle and have 3 ... it's one of those things one can do multiple times to capture its relatively wide and long use. I am planning on doing the new initial production kit for another GB.
Cheers! Bob
