To everyone: Yesterday i purchased the evader bx. It was a breeze to break in. Adjusting the diff is very easy ppl. Take the tire off, take the rear ball cup (drag link?) off w/ pliers. the cv should slide right out, get an allen wrench(don't know what size) and turn the screw allt eh way in, then 1/8 of a turn out. I love my duratrax, it will smoke a losi and a f(*&^% tmaxx! They have come a long way since the maximums. Check em out, it's a top of the line car w/ tons of hop ups and race ready!
