Wiring for model boats



The diagram above shows the basic components and how they are connected to power up a model boat and how they connect.
1. Use a correctly rated fuse. This will protect the electrical components should a fault occur or if you hit a stick in the water that jams the propeller. Its easy to think this is not necessary in a model. I learnt the hard way many years ago when a nut on my prop-shaft coupling came loose and jammed the prop-shaft. This incident cost me a new speed controller and a motor! A 50p fuse would have been a lot cheaper.
2. A connector on the battery is obvious but by adding connectors to either side of the speed controller allows a quick swap out if you get a speed controller or motor fail.
3. Use wire of the correct gauge for the current your motor uses. A thicker wire is always better.
4. Receiver placement. place the receiver in the hull as high above the waterline a possible. 2.4Ghz radio waves do not travel though water and a receiver below the water line will give a poor performance.
