Well I drive an FS2, it's really nice to drive, if your going for a 2WD I would go 100% mid motor. The C4.1 and the Durango 210 would me my choice.
Behind the MCS but you can't buy them
But the mardaves are a good laugh too!
Motor/ESC wise get an SXX TC from JEspares they are £129.00 and will run anything you will ever need. Also I would get something like an LRP X12 motor
I use a 6.5t in my 2WD and 4WD.
