You should be able to do the mm/9l combo cheaper the the vxl system.
Get the mm from here:

and the 9l from here:

Or you can bid on a 9l that I am selling, it is used but works fine:

The 9l has a lot more torque than the vxl motor, kv is 2700 vs 3500, but you gear differently to compensate for the slower turning motor. The 6000 3s pack will be fine. You should get at leat 30mins runtime out of it. A good charger is a wise investment, pays off in the long run!
