Well, that depends. Are you controlling a brushless or brushed(can type) set of motors? Quick and dirty, Brushed motors, no problem - but use a speed control that's rated for the expected peak current draw for both(or all) motors. If it's a brushless setup, unfortunately, you'll need a control for each motor. I beleive Jeti(?) or Castle is coming out with a multi speed control soon, but I don't have any info yet. I hope so! I need a couple.
