This looks like the standard HS-311:
http://www.vegarobokit.com/product_descriptions.aspx?product_id=59&sub_category_name=Servo%20Motors&category_id=41

It's probably a clone of it, and shouldn't be too hard to modify.

For the $50.00 robot, you need two SERVOS (not motors - there's no motor driver on the $50.00 robot) with a large enough torque to move your robot (probably in the 1.0kg-cm to 4kg-cm range)

Hi,

You have already been pointed to a clone of the HS-311, but you can look for yourself in the Servo Data Base the next time you need specifics on a servo.
Regards,
Søren

A rather fast and fairly heavy robot with quite large wheels needs what? A lot of power?

i just picked up 2 HItec HSR-1425cr servos from Hobby horse for about 17.00 EA + shipping. They are continues rotation so they don't have to be modified to be used as wheel motors(if that is what you were going to do with them).

 The specs on the package are :

Operating voltage : 4.8 to 6.0 v
Operating speed : 43.4 rpm+10%
Output torque: 38.88oz-in


***I in no way have any affiliation with the hobby shop mentioned above ***

I highly recommend servotronix servo drives:

and servo motors:
