I didnt know the stock set up worked. And yes,the TZ is cheaper then the TM(both modded). I dont know why,but my guess is because the TM is a direct drop so they expect to sell more. All about makin the money.
I did see that revo when I was there a couple of weeks ago. He won the second or third heat didnt he? I just remember seeing some people shocked about a revo doing so well against truggy's. But I know bri,and I have seen the 3.3 in action a couple of times. If he says he is happy with it,then he is LOL
