I've had many 4wd's including cat sx2 sx3 , k1 , xray xb4 and now gone back to a durango v4 410.
I liked all of the cars , but love my durango

,its easy to drive / maintain / set up and its tough .
i'm running a yokomo b-max2 for 2wd etc , and have lately been considering getting a b-max4 , but after running my 410 yesturday for the first time in weeks , i'm glad to report its staying !!
