Understanding the electronics
Electric Motor: The electric motor is the heart of an RC boat, providing the necessary propulsion. It is typically placed near the front of the boat and connected to a shaft that runs towards the back and extends through the hull's bottom. Brushless motors are a popular choice as they are cheaper and can run underwater. However, they may require cooling, especially if they generate a lot of heat. To achieve this, a water loop can be run around the motor, but this is only applicable to inrunner motors.
Battery Pack: Selecting an appropriate battery pack is crucial. Ni-MH batteries are a common choice due to their affordability and solid performance. Lithium-polymer batteries offer a flatter discharge curve, resulting in more consistent performance throughout the run. It is also important to consider the connector type, such as Tamiya, Kyosho, or Traxxas, and ensure the battery pack has a watertight design.
Electronic Speed Control (ESC): The ESC regulates the power from the batteries to the motor. It is essential to choose an ESC that can handle the current draw of the motor. ESCs are typically water-resistant, but additional sealing can prolong their lifespan. Some ESCs come with a Battery Elimination Circuit (BEC), which provides power to the radio receiver, eliminating the need for separate batteries.
Radio Transmitter and Receiver: These components facilitate communication between the user and the RC boat. The transmitter sends signals to the receiver, allowing for remote control of the boat. It is important to use fresh batteries in the radio transmitter to ensure reliable communication.
Additional Electronics: You can incorporate other electronic modules to enhance your RC boat, such as running lights, motor sound, and pumps. These modules can be connected through manual switches or piggy-backed off another channel using a Y-cable.
It is also important to consider waterproofing and sealing to protect the electronics from water damage. Proper sealing of the canopy and hull can prevent water seepage, and flexible clear tape or high-quality adhesives can be used for this purpose.

Building and racing your boat
Building an RC boat can be a challenging but rewarding project. Whether you're a novice or an experienced builder, there are a few things to keep in mind when constructing and racing your own electric RC boat.
Firstly, decide on the type of hull you want. The hull is the most important part of your boat, as everything else will work around it. You can choose to make your own hull or buy a ready-made one that fits your design. Consider the appearance, speed, and handling goals of your boat when selecting a hull type. The length of the hull will greatly affect the speed and power of your boat.
Once you have your hull, it's time to think about the power system. The power system of an RC boat typically consists of six key components: the hull, cell count, motor, ESC (Electronic Speed Control), prop, and hardware. The motor is usually placed at the bottom rear of the model boat, under the battery. Use modelling glue to fix it in place, and then attach the prop. The ESC regulates the power from the batteries to the motor, so it's important to select one that can handle the current draw demanded by the motor.
Next, you'll need to connect the ESC to the motor. Follow the instructions provided with your kit to ensure a proper connection. Once all the connections are done, secure them with hot glue to prevent them from coming loose. If you want to enhance the range of your boat, you can add a module, and even consider installing a camera to record your races!
Before you take your boat out for a spin, don't forget to waterproof the openings. Build a wall around the openings to prevent water from entering the hull. Grease in the stuffing tube will also help to keep water out and provide lubrication.
Finally, it's time to race! Remember to maintain and tune your boat regularly to keep it in good condition. Enjoy the thrill of speeding across the water with your very own electric RC boat!
