How to Build an RC Outrigger Boat

Radio-controlled or RC boats such as outrigger models tend to provide lazy fun on an afternoon with a bit of added control over the entertainment. Building one involves a bit of engine construction and gluing, but the result provides a fun aquatic twist of RC model play. With a few specific parts, tools, and a complete model outrigger boat, an RC boat can be fabricated in a short time for that next day at the local park pond.

Things You'll Need

RC motor
Servo
Rechargeable battery and charger
Radio transmitter and receiver unit
Glue
Propeller assembly
Water-proof sealant
New batteries

Instructions

- 1
  Obtain a finished boat model with an outrigger frame, preferably one with a wood or plastic hull that is sealed. Glue the RC motor to the bottom of the hull near the stern (rear) with a propeller assembly sticking out the back of the boat.
- 2
  Apply water-proof sealant to all the holes or cavities made in the hull when installing the engine unit.
- 3
  Glue the servo unit to the rear deck of the boat. Attach a receiver unit to the bow (front) area of the boat on the top deck, not under the water line of the boat.
- 4
  Attach the rudder to the back of the boat with a bracket, allowing the rudder arm to twist freely but stay in place. Cap the rudder arm on top with a plastic top to keep it from falling through into the water. Glue a gear to the top of the rudder.
- 5
  Attach a servo belt to the rudder gear. Wrap the same belt around a separate servo gear attached to the engine, battery and receiver by wiring. Test the receiver to make sure it receives the signal to turn the rudder via the servo belt. Check that the rudder turns both ways (left and right).
- 6
  Open up the cockpit of the boat and nestle the battery pack inside. Run wires from the battery pack to the engine unit and to the servo. Seal them so that the connections are water-proof and don̵7;t short in the water.
- 7
  Install new batteries in your RC transmitter/control unit. Switch the battery pack to the ̶0;power on̶1; position. Try the boat out to make sure everything works correctly.
