In what kind of environment, I would be under the impression that
menouverability in close quarters (indoors) wouldnt be adequate, If it
is for outdoors unmanned navigation experiments etc they are excellent
if you keep the weight down.
Im interested in what your project is.
an excellent place to look around is towerhobbies.com

Yes the electric rc dragsters are very fast, some of them will outrun
most cars in the 0-60, but they are just that dragsters, bad things
happen when you take a motor thats used to 7.2 volts and you give it
24. Most electric r/c models are not quite as quick as the nitro models
but they can not be called slow. The battery life however your looking
at 15 minutes if your lucky, unless you drop serious serious dough on a
li-ion pack, your 3 amphour pack with a decent 12 to 15 turn motor will
be dead rather quickly. However charging this same pack is usually
done in about a half an hour. For a bot you can expect much longer
run time because i cant imagine a bot that wants to be peged at 20 mph
all the time, honestly if you want to use a r/c model use the shortest
gearing you can and a 27 turn model to get the speed down, itll be
plenty fast for a bot (unless for some reason you actually need the
speed), itll still accelerate with a load (not that the suspension is
meant to support extra weight), and youll be rewarded with good
runtime. I do have to mention that the rc models have suspension thats
not meant to support extra weight, this can be tuned out to an extent
with a quick change of the springs.
However if your buying your model at radio shack forget most of the
things i said above.
