if its the common scooter motor people seem to use, its the large diameter one - something like this http://img.auctiva.com/imgdata/4/7/8...09684322_o.jpg - a 24v 500 watt. These are usually connected to a 30amp max/peak current of 30 amps.

However, alot of people use Botbitz TZ85A converted ESC to run these motors. - UK supplier http://ranglebox.com/product/botbitz...2-brushed-esc/ or DIY witha hobbyking purchase (other libnks available but this was a quick google search: http://www.robowars.org/forum/viewtopic.php?t=1609)


I will be using a self programmed TZ85a to power my 250watt 24v electric scooter motor.

Others may use other things...
