In a nutshell it's just a stock slash 4x4 but I swapped out the crappy plastic shocks for some aluminum ones from a stadium truck, and just have a basic AM radio (works great).

the common sizes are 190mm or 200mm. The 190mm usually lets the wheels look more "scale" and stick out or be flush. the 200mm will cover the wheels a bit better and are more for the touring car racing setups.
