get the new xxx-cr or a used bk2, maybe even a b4, even though i am not a offroad AE person. I'm more of an offroad losi person. Get either the xxx-cr or the bk2, my friend has a b4, and when he drove my car, and my car just has a basic setup, he said "wow, now i want a xxx-cr or a bk2" he said it felt so much smoother and turns like nothing compared to his b4. and he races his b4. ive driven his b4, and preferably, i like the bk2 better. no offense to ae people. just like the Losis better.
