here I offer Ehang Drone 2 with 4K camera. Device was actually never used, but tested after the purchase. All elements are new, battery is charged-dischaged once, one flight shown perfect performance with over 100 meters height reached and flight time of around 20 minutes. Super-easy to control with the phone (was tested both with Android 7 and iPhone iOS 11). 

Please check local regulations for using drones, for me German ones turned to be too complicated. This is the reason for selling. 

Sending within EU is possible.
