Testing a TOROIDAL propeller UNDERWATER

Build your own CPS 5 with our online course: MIT inspired toroidal propeller model: In this video we test the toroidal propellers on our underwater drone. You can also call it a DIY submarine. We test how fast are they, are they any efficient, and whether they are safe to touch at max speed. If you feel like this video was has improved you as a person, please SHARE THE VIDEO. Our mission is to make building underwater drones as cool as the flying ones.
