What kind of motor?, you cant run two brushless off of one esc, the esc and the motor "talk" to one another for optimum performance. Brushed is another story, Traxxas makes the EVX2 (actually i believe they are built by Novak), which i have three of, and they run two motors with up to 14 cells. i also have an older Novak 12 cell, these esc's work just fine as far as im concerned. You can get a new EVX2 on ebay for around $60-$80.
