Hi Steve, as you are using the exact motor system I have been
planning to buy, and as they never seem to publish the info I
want, can you tell me about how much current the motors draw in
various loading situations?

I want to use the L293D H-bridge chips, which are rated for 600mA
tops [ie, with good heat sinking]. Did you need to use an H-bridge
rated greater than this?

thanks,
- dan michaels
