Then again, it's nice to keep the cg low, so having the heavy motors in the bottom would probably be preferable. Note that I've never used the Fisher Prices, so I'm just guessing. If someone who knows a bit more than me could comment, that would be helpful.
I punched the numbers into the JVN calc and with a reduction of 48:1 (big reduction) I got a good speed of around 8 fps with a current draw of 13 Amps per Motor. Perhaps the smallest amp draw I've ever seen in a drive.

Going from CoFs of 1.4 to 0.1 makes a huge difference
