They are using brushless motors and are either air cooled or water cooled!

I agree too. If you look at the large R/C electric model aircraft (jets and other large scale models) and see how they are used you will gain a lot of respect for the brushless motors, controllers, and how many amps they routinely suck up with well designed air flow systems. A water jacket can be fitted around them or a fan can be installed on them for CNC use.
