It's very difficult to see what you are trying to achieve, from this message and all of your previous messages.
You have way too many devices. None of them work. It's hardly a surprise that you are getting nowhere.
In an earlier thread you were advised by another poster to break things down into smaller pieces. Since your goal is to get the model sailing in July you need to focus.
I suggest that you concentrate only on steering and propulsion. These are two quantities you can send from the transmitter and put into action on the ship.
What device are you using to move the rudder? If you are using a stepper motor I would advise replacing it with a servo.
What range of movement does the rudder need? Assuming 0° is straight, in line with the keel, what angle do you need to port and starboard? I expect ±90° is plenty.
Next, how are you dealing with propulsion? I expect you have a single propeller, but maybe two. How are you driving the propeller? A stepper is no good. You need a simple brushed or brushless DC motor. For two propellers you need two.
Most people use servo control signals to control motor speed, so you should too. Centre stick is off. Stick forward is propeller driving forward. Stick back is propeller in reverse, if your propeller design allows it.
That's it. Two electromechanical elements. Two control signals. Simple software. Done.
