Any advice on building a drone from scratch?

I’m a physics student at my school and for our physics club, we want to build a drone completely from scratch. Any advice? Motors to use, camera, controller, anything. We also need a budget so our school can fund our project if you know how much it would cost to build a drone. Ideally, we’d like to 3d print the frame and propellers, and code everything ourselves. via /r/drones https://ift.tt/2LdXJ1R
