Yesterday I was working in my workshop and noticed how all of my old dead RC planes just sit there. Like they have no purpose. So yesterday, I decided to put them to use. I was going to build an RC boat! So here is what you will need to get started:
hot glue gun
Vice (To hold the wood when you are cutting it)
1 rechargable 1.5 battery
2 large egg cartons
1 roll of Duct Tape
An RC receiver
An RC remote
2 hours of time
Step 1: Building the Body
Instead of having your typical boat hull, I decided to go with a hovercraft-ish hull. With a flat top, and a open bottom to allow air to move in and out while the boat is moving. But, I realized that that would cause friction and a vacuum in the bottom. So to build the hul, you have to seal the bottom of it, too. To begin, you will have to cut your large egg carton in half. Then, cut of a large middle section off of both of them and Duct tape the two ends together. Then, take the middle section and Duct tape it to the bottom of the craft. IMPORTANT! Make sure that the bottom is sealed!!! Next, put Duct Tape over and foam that is showing.
Step 2: Mounting the Motors
To begin this step, choose which end will be the boat's front. You will ant the front to have no excess Duct Tape on it. Next, take a small extra piece of foam. Then, cut it down to about 1 inch wide and 3 inches long. Cover it up in 2 layers of Duct Tape then cut of the excess Duct Tape. This will absorb the vibrations. Next, hot glue it to the back of the boat. Next, take some Balsa wood and cut a small 1 inch wide by 4 inches long. This will be the motor mount. Next, glue the wood to the foam piece. Let the wood go over the boat's end by about 1 inch. Next, take 1 of the motors and glue it to the wood. Then, take a small piece of Duct Tape (about 4 inches) then slice the width of it in half. Use 1 f the half's and put it across the motor and secure it to the balsa wood. Next, cut out a 1 inch by 1 inch square out of Balsa wood. Glue that to the other end of the motor mount. Take your other motor and glue it onto the balsa wood square with the shaft pointing sideways. This will be the turning motor. Then, put the other piece of Duct Tape and Secure the motor to the mount. Finally, secure the propellers to the motors.
Step 3: Finishing Up
This has to be the hardest part of the entire project. Fist, measure out how big the RC circuit board is, then you have to make a housing for it. Then, glue the housing towards the front, then you have to connect the motor wires to it. Then, add some space to the compartment for the battery. Then, you have to water proof it. Next, take a small piece of foam and cut out two pieces that are 1 and 1/2 inch tall and 1 centimeter wide. Hot glue them together, then put Duct tape around them. Glue this to the back of the boat. If your receiver has an antenna, take the antenna and wrap it around the foam on the back. Then Duct Tape it so that it will stay. Then, you are ready for water! Enjoy!
