Bait boats give you an easy and fun way to spread fish food over the surface of a fishing area to draw fish, but it can be prohibitively expensive to purchase specialty radio controlled bait boats. Building one of your own is a viable alternative, and you can use practically any radio controlled boat that’s big enough to carry a hopper full of bait. You’ll have to install an additional servo onto the boat that will control the bait hopper and dump it when you activate the correct switch on your controller; but once that’s done, you’ll be ready to drop bait just about anywhere you want.
Place the radio-controlled boat on a flat surface where you can work on it. You may have to remove some pieces of the boat in order to make it work properly as a bait boat. The plastic container should rest on the back of the boat so that when the trap door you will install is opened, the bait will fall out of the container and into the water.
4 Wire the servo to the secondary switch on the toy boat. This is the function that will be triggered when you flip the switch on the remote control. Children's toy radio control boats do not have this functionality. This is why selecting a boat and a two-channel radio from a hobby retailer is important. The boat kit will include the necessary instructions you will need to be able to connect the servo.
Waterproof any connections you made in the boat with silicone sealant to complete the installation.
