The ubec will take the place of your 4 aa batteries. It is hooked the to wires going to the esc. It takes the 14 cell voltage and cuts it back to a 6v usable current. You won't need the 4aa batts and it is easier to mount and won't have to be recharged or replaced.

It would depend on how you mount the cups if you can keep the mechinacal brakes.
