If you want to hook two speed controllers with separate batteries to one receiver you must take the red wire out of one of the controller's receiver plug. Very carefully remove it by releasing the brass prong out of the plug with a straight pin. I just put shrink tubing over it so it doesn't short out on anything and you're good. If it's a Sabertooth pull the Red wire on both plugs to the receiver. Now if it's one battery feeding both speed controllers, it really doesn't matter as it's the same power source.
