In any case, I would recommend a five cell (6.0V) NiCad or NiMh battery pack over a 4 cell for safety reasons as you did not specify which radio you will use. All radio systems have a drop-out voltage (no response threshold). One early 2.4 radio system was notorious for having a high threshold voltage for the receiver. If you stressed the servos and had a not fully charged 4 cell Rx pack, you would lose all control for a few seconds while the receiver rebooted.

The only downside I have experienced with a 5 cell pack is that there is a JR retract servo that will not operate at all; but the voltage doesn't hurt them. Don't remember the model number (its hell getting old) as I got rid of them when I replaced 4's with 5's.
