the best carpet 1/18tc hands down is the x-ray m18 pro....
Exotek makes awesome chassis for the m18 as well.
The Exotek is a great upgrade for the stock m18.
I have the vendetta tc and it is good....but it is not on the same level as the m18....Mine will become my driveway/parking lot racer....while my m18 will be for the carpet. This spring Duratrax will be releasing a CF chassis for the Vendetta TC and it will take the car to the next level...but it will be costly compared to a m18 pro kit....about $150 more than the m18 pro....with comparable components...ball diffs, cf chassis etc...
