The MM esc is overkill I dont know if it is limited on max rpm? you can turn these little motors up to 100,000rpm

If you want to run high voltage the Quark 33a ESC is good for 5s the Mamba ESC is good for 4s as far as upgrades get the MIP diff's with the Asc. carbide balls and they will last a lot longer with the added power. :)

The RC18B is a onroad only car I have been running a 4s 2100 Maxamp pack in for almost a year now with a variety of motors and the driveline has held up great it's basicly a RC18B ft kit with a carbon chassis and MIP diff's with CVD's in the front and it's been over 80mph with the 6800 Mamba on 4s I'm hoping to get it over a 100mph by July for the worlds fastest RC challenge.:032:

Runtimes with a 2100mah pack?
8000 Mamba = around 30min
6800 Mamba = around 45min
5700 Mamba = around 55min
Wraith 7k = around 25min
