Got a pretty good deal on eBay. I think it is a good deal. The auction was for a DJI Flame Wheel F550 ART, just add your own remote, and lots of spare parts including 2 brand new in the box flight controllers, one of which I needed for a future project.
I haven't seen one of those for a few years, they were very popular for quite some time though, and still have their uses if you want to custom make your own drone.
