To build a drone is easy, with instructions of course. Building a complex drone could be hard, sometimes its not, just as long as you have fun with it. There are drone kits you can buy to build and piece together with instructions. Or you could build it from scratch. Of course you have to start with buying a frame for the drone, easily accessible through websites. You’ll need a motor, connectors, propellers, etc. If you want to film from high above you’ll need a camera. Build it all up, and you’ve got a drone!
