You'd be screwed...just
like if they were in parallel. Here are some senerios:
SERIES:
-one motor fails open
circuit - drivetrain stops working on one side and no more harm done (just need
to replace/fix the one motor that broke)
-one motor fails short
circuit - the other motor gets the full supply voltage, and unless the driver
notices reduced power in time, burns out
PARALLEL:
-one motor fails open
circuit - the other motor takes all the load, and unless the driver notices, it
burns out
-one motor fails shorted
- this is like shorting the output terminals on the esc, either the fuse blows
or the esc is toast
I think it's a matter of
finding batteries, motors, and escs to make a workable combination. That will
help determine whether the motors should be wired in series or parallel.

Also, if you wire the pair
of motors driving a side of the tank in SERIES you can run twice the voltage
and half the current. This is usually a lot easier on the esc. The motors will
not fight each other at all in this configuration.
and if one of them should suddenly fail?
