The Emergency Rescue Boats ESC/Receiver, (Electronic Speed Control/Receiver) Is the brains of the boat. It processes the signals that you send with the Controller/Transmitter and sends the correct info to the motors, lights, and water cannon.
The ESC/Receiver is located under a cover box in the highest part of the upper deck, as far from any possible moisture as it can get.
To remove the ESC/Receiver board, you must remove the two screws holding the ESC cover box from the upper deck. You will also have to carefully remove the Silicone Caulking/Glue from the hole in the ESC cover box and from the wires passing through that hole. Carefully scrape and pull the caulking away, until you can move the cover box out of the way. Take special note of what is plugged into where on the board, and then you can unplug everything from the ESC/Receiver board. Take the single screw from the board and lift it out.
The ESC/Receiver Board is secured in place on locating posts with a single screw to hold it in place. It is oriented with the eligible letters correctly aligned to you looking from the back of the boat with the boat pointing forward from you.
