RE: Converting MT2
The only good thing I found with 2wd is that when you do big jumps you can alter the way the truck lands by using the throttle/brake as the unbalanced force on the rear throws the back of the car. It takes a hell of a lot of pratice and some broken parts (I strongly suggest a roll cage) but its worth it at a skate park or somewhere where you can really show off and feel really smug.
