With that current rating, you could go either way. The six volt pack will give you both more speed and more torque for both servos.

If you wanted to mix them up, you could always use the higher torque for aileron, elevator, and rudder with the lower torque for the throttle. That is if you are using one servo for the ailerons. If you are using two, well, for a trainer you can go with the lower torque, one on each side, higher torques for the rudder and elevator.

If you go with 4.8 volts, you can do pretty much the same thing but with the lower torque (as noted) and speed (also as noted).

Either way, you are fine.

That is a big battery pack. Yeah, overkill considering the standard pack that comes with most 72 MHz radios is 4.8 volts at 600 mah.
