Hey,

For antweights, I'd definitely recommend heading over http://robotwars101.org/forum/. It's where most of us ant guys hang out and there's a wealth of information there.

In answer to your question, the standard setup that I'd recommend to new roboteers would be one of Rory's kits. They come with the control board, receiver, motors, and wheels, all in one package. You can find more information about them here: http://robotwars101.org/forum/viewtopic.php?f=1&t=2187.

Best of luck .
