RC Car Robot

There seems to be precious little useful information on the neweeg website
about the details of the car, but lots of n/a's.

Can't even tell how large it is. Is it even big enough to carry something the size of
an Arduino bd, and possibly a few extra batteries?

Secondly, the forward speed of the car is a critical bit of information. Most R/C
cars go "much" too fast to be useful as a microcontroller-controlled robot. The
sensors and s.w. can't react fast enough.
