doesnt look like anything new has really changed except the MMM system. from what i read just the same traxxas mumbo jumbo. hex screws, revo style this an that, sealed shafts an drive train its all stuff thats been already been on a traxxas vehicle. emaxx fans probably are going crazy but my bet is most of them have already perfected there emaxx with a MMM system in it to there own liking so i think its a totall waste not very many people are going to buy espescially since theres the new slash 4x4 out. Not very many people want to put out that kind of money. when most people buy the lower priced version first to see what is like an if its a bang they go crazy with it otherwise its just another item on the shelf. but hey traxxas people got to make a living somehow right.
