I'm a hobbyist and homemade drone builder for about 3 years. What DJI did here is simply unable to be done on your own no matter what components you get. A light, foldable, compact, safe, fast, stable, smart, equipped with powerful gimbal, camera and sensors, and lasting 25 minutes of flight with a single [smart] battery. Not telling all the flight modes and camera features. This is a piece of the high technology. A beautiful combination of hardware and software. It was worth every penny.
