I don't see the advantages to the spinning lots of props on a frame with no apparent forward. What do these gizmos do (besides consume money) that traditional aircraft can't. The device seems like a very complex novelty. All those motors, props and ESC's all have to work in harmony. A failure of any part and oops! there it is. There's no redundancy (gliding/ auto rotate) Just an observation from an ignorant point view. I wouldn't mind hearing from enthusiasts who could enlighten me on the subject. From a business aspect it's genius every sale results in the sale of lots of breakables X 3 or 4 or 6 or 8. With no inherent stability what could go wrong?
