That depends on where you live man, A modified MT will finish first in an MT class. I race buggy, but I will bring out the revo if enough interest is there. I honestly have kept my revo just to play around on my track with because I will not run the buggy out there.
I just don't understand the point of posting a thread like this, I mean if someone wants to upgrade their MT I don't see why that is such a mystery?
