Introduction: Mini RC Jet Boat
This is a 3d printed RC Jet Boat with a 3D printed Jet Propulsion or also called jet drive. All parts are designed and constructed by my self. The goal was, to design a small and very compact RC controlled jet boat, where all parts could be build with a 3d printer.
Instead of a propeller behind the boat, the jet system works just like a jet ski, by a propeller integrated inside the boat moving the water in and out pushing it forward. Not only the hull of the boat is 3D printed, but the propeller, motor mount, servo holder, battery tray and even the servo coupler! The brushless motor was from a RC drone and with a 2 cell 18650 LiPo it was too powerful.
The hull of the boat is also constructed and printed by my self. The impulse jet, which I got printed mostly in pla, is allready tested a lot and runs really awesome. On a other version of the boat I am running the same jet but with all parts printed in ABS. Even the printed ABS or PLA propeller holds up to the brushless outrunner on 2S just fine!
