If your engine performance is satisfactory without a regulator... fine.

The advantage of adding a $4.00 regulator,
is having a constant voltage throughout the battery charge. 

Remember that a two cell fully charged is 8.4 volts,
and at discharge is near 6 volts.

The Deltang Rx monitors its supply voltage and works out how many cells are supplying it.
It then stops driving the motor if the voltage falls to a level to endanger the cells.

This works if it is supplied with one, two or three cells,
it chooses its cutoff voltage accordingly.

If you use a regulator to supply the Rx,
this ability to monitor the battery voltage directly is lost.

Instead, if you are using a single cell, you can connect the cell output to the pad,
so the Rx can still monitor it and stop the motor if it gets too low.

There are of course other ways to protect the battery as Bob mentions.

Also works for 2 cells.

I use 2 batteries in series for some locomotives.
