Castle Creations sidewinder esc and 4600 motor kit. Heres the link I have 1 in a 2010 sand scorcher, http://www3.towerhobbies.com/cgi-bin/wti00...LXUTA1&P=SM, they have a 4600 and a 5700 and if you get the castle link setup it is fully programable with a computer.
I would buy the weller with the adjustable heat control station you have to buy them seperate but it is well worth the money in my opinion. If you are in the states a most any hardware store like Lowes or Home Depot should have them available.
