The rumor is another improved version is coming. At least that is the reason everyone is selling their 3.0's. Has anyone heard of what improvements there are suppose to be? I have a 2.0 I really like and am using quite a few of the newer 3.0 technology on it. I have replaced the 4 wheel cvd's with dogbones, an easy upgrade. I suggested a quick change center dif mount, that with only 4 screws the top pieces could be removed to change the dif. I'm actually considering getting a cnc guy to make me one. Losi offers one, but it's hardly a "quick" change one. What would Losi guys like to see incorporated in the 4.0?
