Aye, they should really indicate whether they are balanced or not, as it's obviously going to be a concern. I had a look around and whilst most people agree they aren't balanced, there's no definite answer.
(I did find a few other sets, they all look pretty cool)
I'm inclined to agree with Stella that they are meant as a display item seeing as they come unpainted.
