Hope you knocked on wood while writing that Bill :)
Fact is, lots of folks have killed servos when running higher voltage
packs and lots of folks have used them for ages with no problems. Take
your pick and go with it, but a voltage regulator to keep things at 6V
is not a BAD idea, it may not be totally necessary but it's not hurting
anything being there other than being another link in the chain.
Then again, modern (fast and strong) digital servos don't require the
extra zip of 6 volts anyway. Years ago when all this started, the servos
weren't anywhere near the performers that modern servos are, and they
were all analog. Today's high capacity batteries also suffer very little
voltage drop under a 4-6 servo load.

A voltage regulator insures that your digital servos and RX don't get
too much of a good thing,
Every digital servo that I am aware of, and I run most of them from
JR281's to 8611's and Futaba 9252's, CAN take 6 volts without a
problem. Old wives tale. 7.2 volts is a different thing. But I love
this myth about needing a regulator with 5-cell packs.
I have run 5-cell packs (Nicad & NiMH) in everything from D/HLG to
molded TD to helis to 40% giant scale aerobatic planes for several
years, ALL with digitals of various sizes, with not a single problem.
Run a regulator if it makes you feel better, but it is totally
unnecessary. And even in my big aerobatic planes I cannot tell the
difference between flight #1 and #5 (when I charge).
The very worst thing that you "may" observe is a slight jitter when
you first turn on. Lasts about 15 seconds as the surface charge goes
away.
And to the point about stalling, etc. causing a need for a regulator.
Sorry, the regulator does nothing there. A stalled servo pulls what a
stalled servo pulls, irrespective of a regulator. Most OEM plugs are
rated at 3 amps continuos (means no real rise in temp at that
amperage) which is well below the full stall current for most glider
digitals, and right at stall current for say an 8611 or 9252.
