I have seen the TC in action at my LHS. It like the Pre MGT version. I almost confused the two from a distance. I think the TC comes with a tt18..correct me if I am wrong. still pretty big. As long as you like it, thats all that matters.
Tamiya has fazed out the TC, so I don't know about parts availability in the future, but if you are looking just to thrash and bash, you should have a good time with it. I remember when I was first getting into nitro, I almost bought the TC over the Maxx. The TC was brand new, not even out yet, but in the end I went with the maxx. What does this have to do with the thread? Not much, I'm just walking down memory lane.
