This is a bit of a hard one, A mate of mine just brought the rtr and i know he is going to have some greife with things like the servos etc and it soon wont be a good enough machine competition wise
In your post Todd you mention about been a good profesinial racer and wanting a good machine... Right then and there its time to relise that the rtr is not for you!!, Forget it champ as it will be nothing but problems.. Get the roller (MBX6T)

and build a proper race truck not a kids toy
