Not wanting to spoil the fun, but... dude, did you really consider what you did before you ordered?
Now I don´t know the Katie kit, and it *may* just be one of the (very few) better ones, but apart from the motorcycles, all BTD vehicles I built so far were pewter crap.
Of course, where else to get a quarter scale Katyusha. And I guess you might make a stunning model out of it. :roll:
But couldn´t they have used a ZIS lorry instead?
