Hi, I'm new to Pixhawk. I'm making a boat. I do have 2 brushless motor with ESC and 1 servo which is connected to the rudder. How can I connect them to the Pixhawk 2.4.8. What changes should I bring in the parameters? 

From readings, I come to know that servo should be connected to RC1 and motor to RC3. But what should I do when I have 2 motors, which are kept in both the ends. 

Thank you
