This is not a joystick controller, it only can control one motor. For the dual power, you need to use two controllers to control two motors.
Not every motor can run at the first time when connecting to controller as the colors. You may need to adjust wires connection order to make motor run correctly. The correct wires connection makes motor running smoothly and not noisy.
