Oh wow, I think you got the updated kit. I bought an FT B4 a few years ago, and the box art was different.
The main difference between the Team and the Factory Team kit of the chassis appearance-wise is that the "Carbon" chassis. The "Carbon" naming is a little misleading since it's not "Carbon Fiber" but a carbon-injected into a plastic mold...
Appearance-wise, the plastic chassis is quite black. The "Carbon" chassis looks like there are threads and other stuff on the surface... It's also a bit grayish/light black in color...
The best way is to take it to your local track or local club meets and see if you can find someone with the regular Team B4, and compare his/her chassis with yours.
My only gripe with the FT parts are the front arms. The FT ones seems to be a lot more brittle and break with the smallest taps. I missed the old nylon arms like on the old RC10CE. I've never broken a single one of those, compare this to a bucket full of FT B4 front arms that I've accumulated...
:P
But to answer your question, from the looks of your pic, that looks like the "carbon" chassis. I can see little threads and other particles that were mixed into the mold to make this chassis "carbon"
