E741 Flysight drone from Aoweishi is one of the better drones with a 1080p camera and viewing screen. To buy all of the parts separately in the US you would need a gopro, tablet and drone and that would cost about $1500 and it would not be seamless control. I do hope they make a 4K version soon. You need to buy in bulk of over 10 pieces to get a lower price.
