Hi, for a school science fair kind of project I need to complete to graduate and get a diploma. We (me and a friend) chose to make a drone. Do I make it a quad copter? Since it's more motors, it must be more expensive, were using a 3Dprinter and designing the thing ourselves, do you have an idea of the minimum price it would be? The school has a 3Dprinter, so that not included. Thanks for your help.
