Choosing RC Boats

RC boats typically use two-channel radios that are designed for ground-based craft, such as a boat or RC car. These radios use a different frequency range than airborne systems. It's not wise to use a two-channel airborne system in an RC boat. This is because in an RC boat, one channel, usually driven by the left-hand stick, is used for the throttle, and the right-hand stick drives the rudder servo. Most RC boats use a gear drive system to help the motor generate more thrust. Electric-powered boats should always be outfitted with a throttle control that allows the boat to move in reverse. In the case of a sailboat, the throttle servo is usually replaced by a sail winch servo. This allows the operator to trim the main sail as the wind shifts, just like a real sail boat. The radio compartment of the boat needs to be waterproof to protect the electronics inside. Rubber seals are installed on the prop shaft of motor boats to keep water from entering the hull. RC boats don't have to be limited to two servos, nor does the two-servo limit mean you can't do some special effects. Try installing an automotive windshield washer motor to a pickup tube that extends into the water and hook the other end to a fire hose.
