the RCX has a current limitation per output of 550mA and can provide only
330mA mean motor current according to the data sheet of the motor driver.
For the battery boxes it depends on the batteries,
the lower internal resistance they have the better.
A NiMH block battery in a 9V box can give quite a whack
(NiMH is good for high current but has lower voltage).
I don't have the RC buggy, but because its motors are much more
power-hungry I suppose that the controller can provide
several times the current of an RCX output.
