the S-tanks motors didn't burn up. They did severely overheat though due to
too high gear ratio, running at partial throttle settings, and basically using
the wrong motor for the gear ratio.
If building the S-tank again, I would probably ise the sprocketed geared motors
Steve found and add a sprocket to the drive hub to reduce rpm even more to the
tracks. That would let the motor run at full throttle and multiply the torque
to the tracks.

Don't do it ! I'm not aware of anybody in this hobby overheating a motor. Has
anybody done it ?
Motors should stay sealed. There's a lot of dust, dirty, grime, and paint at an
R/C Tank battle. The last thing you need is any of it getting in the motor.
Drilling vent holes is too much risk and too much effort for no gain. If you
feel strongly, use heat sinks and fans, but leave the housing in tact.

On the idea of venting the motors, think its possible. Cracked one open this
afternoon to take a look. There is about a half inch of space between the
magnets. That should give enough room to drill a series of 1/4 inch holes along
the length of the side. I think i can maybe even get a few holes around the end
too. Did not drill any today as winter has eaten my shed. The motor even
worked after i managed to get it together again, impressed with myself ;).
