Building a remote controller for a toy boat is a fun and challenging project. Using basic components from an RC boat kit, you can transform a simple toy boat into a remote controlled boat. Components for a remote controller can be purchased at hobby stores or on the Internet, and can be used for other RC vehicles in addition to boats. The process for making a remote controller involves attaching a control panel to a transmitter and receiver through an electrical circuit.

Skill level:

Things you need

  • Toy Boat with Electric Motor
  • Radio Transmitter
  • Radio Receiver
  • 12 or 13 Gauge Wire
  • MOSFETs Power amplifier
  • 500 Ohm Resistor
  • Soldering Gun
  • Screwdriver
  • Super Glue

  1. 1

    Take apart the RC servo case with a screw driver. An RC servo drive is an electric amplifier that is used to power an electronic motor. Components include gears, wires, and a motor. Remove the gears and wires, but keep the circuit board intact.

  2. 2

    Solder the amp, resistors, wires, and connectors in to the hollowed out servo case. Position the battery and motor on one side of the case so both can be connected to the power amp. Position the power amp in the middle of the case so it can be connected to the battery and motor as well as the circuit board.

  3. 3

    Connect the battery and motor to each other, as well as to the servo connector. Connect the negative end of the battery and motor to the negative end of the servo connector using 12 or 13 gauge wire. Connect the positive ends of the battery and motor to each other.

  4. 4

    Plug the servo into the connector components of the toy boat. The boat's motor should have a channel for acceleration and a channel for directions. Connect to these inputs by running 12 or 13 gauge wires through server connector slot.

  5. 5

    Assemble the transmitter from parts in the kit. A remote control transmitter kit is a set of components for assembling a remote controller for a boat, and can be purchased at most local RC hobby stores. A typical transmitter kit comes with a case, adaptor, power switch, and power unit, in addition to the signal transmitter itself. These components can be assembled relatively easily; the power unit and switch are connected with 12 gauge cables, and then installed in their respective slots in the case. Antenna may need to be inserted at the top of the transmitter, depending on the model.

  6. 6

    Test the strength of the signal between the transmitter and the receiver/servo. When you push accelerate, you should see the propeller turn. When you turn the steering wheel, you should see the rudders turn in the direction you turn the wheel. If this does not occur, check the strength of the power supply to the transmitter, receiver, and motor. Replace batteries if necessary.
