High-Speed Planing RC Boat

thingiverse

UPDATE: I have designed a new engine nacelle that lowers the props about an inch or so, significantly increasing speed to the point where the boat takes off on a 3S LiPo! It's highly recommended to use this nacelle instead of the original. While I've built numerous boats using 3D-printed 2212 Brushless Nacelles, the boats themselves are always quite ugly and made from soda bottles. Therefore, I've been working in Freecad for a while to design a decent RC boat hull. This is the result! To make this work, you'll need the following: - 2x 2212 Brushless Motors - 2x 3mm to 6mm Prop adapter - 2x 30A (or more) Brushless ESCs - 1x 3S LiPo Battery - 1x Standard RC Servo - 1x RC Radio System My boat has a pump-assisted cooling system, but it's not really necessary. For hardware (I recommend all stainless steel!): - 1x M4x60 - Rudder - 4x M3x10 - Rudder and Servo Mounting Plate - 4x M3x8 - Servo Mount - 8x M3x6 - Motor Mount To assemble, print out all the hull pieces and stick them together with ABS slurry. I recommend starting with the Hull, making sure it's smooth and nicely joined before attaching the motor nacelle. I've attached cut-up .stl files of the hull that will fit in a 250mmx150mmx150mm print area. If this doesn't work for your printer, the full hull is available for your own cutting. After installing the motors and verifying their functionality, fill the cable holes with Hot Glue or Epoxy. I recommend Hot Glue as it can be re-heated to allow for replacement of the motors. <iframe width="560" height="315" src="https://www.youtube.com/embed/F28BzrNNayg" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>
