It's a good mod, there's just an easier and better way to do it. Just bend the back of the heat sink down, and solder the motor to the top of it. VERY clean, and no need for an extra positive wire.
I just don't see much need for a dual motor car if I have a motor with alot of torque and 3 cells.
Didn't mean to step on your toes, Joe millionaire.
