Yes, it's OK.

But when you run a higher voltage, there is more resistance in the
circuit, and the batteries will run down more quickly than a 4-cell
pack of the same maH capacity running at 4.8 volts.

Keep tabs on the voltage of the packs for a while.  You should
learn from experience how many flights you can get before
the voltage drop becomes critical.

You're asking a basic question in electricity. First, you should check
your literature regarding voltage on the servos. I'm pretty sure
they're rated for 6V. If the servos are, then the RX certainly is
assuming they're the same brand.

Next why would one want to use 6V over 4.8? The reason is for a faster
transit time and more torque from the servos. This requires more
current hence a higher voltage. Alway remember that it's the voltage or
pressure that makes the current flow. If you need more flow, you need a
higher voltage.

Finally, what is the downside to using a higher voltage? Obviously your
batteries only have so much electrical fuel (mAh). A higher voltage
will use up the capacity of your batteries faster. A solution to this
is to use batteries with moe capacity or use an additional battery pack
to increase the total capacity.
