3D Printed RC Sailboat

I am a grade 8 student in Corpus Christi school. I have been recently mastering the form tool in Fusion 360. I have always had a passion for sailboats, so I decided to make a small RC sailboat with this tool. Using some servos I had lying around as well as and receiver and small battery. This boat is relatively small but I printed the parts on my Ender 3 but the hull I had to have it printed by another a 3D printing company. Using the stuff I learned from this smaller project I want to integrate in to a much bigger craft.

• 3D printer (I used an Ender 3)
• Liquid electrical tape (Can use electrical tape as alternative)
• Wooden dowel (.2in) (One section 5.5 in long (Boom) and the second (Mast)
• Thin Gauge Wire
• Sailcloth
• 1 9g servo (Modified)
• 1 4g servo (Unmodified)
• RC receiver (I used a Flysky FS-i6)
• 2s micro battery, JST connector

• Print the Hull, Mast, boom, Boom to mast Connector, rudder.
• Print the cabin and coat the sides with the liquid electrical tape, depending on how big the cockpit is for your boat, for me I used about 4 coats (Note: Would recommend test floating and if water gets in either add more tape or liquid electrical tape coats)
• Using the boom and mast link them using the Boom to Mast connector. If the Boom is too loose you can either rap the end in electrical tape or glue it in place

Making the sail is probably the hardest part of building this boat

• Using the boom and mast linked together draw a triangle inside the two pieces.
• Using the thin gauge wire poke a hole in the sailcloth and wrap it around the mast, repeat this process on themes about 5-7 times and then after this repeat the process along the boom about 4-5 times

Rudder:

• Print the file attached below
• After the rudder has been printed make sure that it fits in the rudder slot on the stern of the boat.
• using a soldering iron on the small portion of material behind the rudder slot melt a small hole maybe 2mm deep.
• After this is completed insert a piece of thin gauge wire into this hole and glue it down. Insert the other end into the hole in the rudder. After this is completed just attach a separate section of wire to the top hole in the thin section of the rudder up top and attach that end to the rudder servo

• Attaching the electronics should fairly simple. use the picture above for reference. I have marked all the places were the electronics should be placed in order for proper alignment and so everything should fit. I would recommend water proofing your electronics as the seal created by the cover is not perfect and the slot cut for the main sheet will let water in when keeling.
• In order to get your main sheet servo to work it must be a 360 degree servo. you can either buy one or modify a regular 9g servo. I have attached a video below on how to do so

Now you have completed the project! I would recommend test floating it in a bath tub to make sure everything balances right then you can take it out too your local pond or lake and sail away.
