High-Speed Planing RC Boat

thingiverse

UPDATE: I have added a new engine nacelle design that lowers the props about an inch or so. This *significantly* increases the speed, to the point where the boat comes up on a plane on a 3S LiPo! Highly recommended that you use this nacelle instead of the original. While I've built numerous boats that use 3d-printed 2212 Brushless Nacelles, The boats themselves are always quite ugly and build from soda bottles. Therefore, I've been playing for a while in Freecad to build a decent RC boat hull. This is the Result! In order to make this function, you will need the following: - 2x 2212 Brushless Motors - 2x 3mm to 6mm Prop adapter. - 2x 30A (or More) Brushless ESC's - 1x 3S LiPo Battery - 1x Standard RC Servo - 1x RC Radio System My boat has a pump-assisted cooling system. It's not really necessary... For Hadware (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, and making sure it's all smooth and nicely joined before attaching the motor nacelle. I have attached cut-up .stl's 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 in 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>
