I had difficulty selling mine too. It still works on occasion so I'll keep it as a backup. I feel it is better than the Classic 3 I use instead, but the Classic has the smart controller.
If and when that day comes, the drones can still be flown. The FAA just won't be able to link a registered owner to them in their database. That would be counterproductive to their goal. When drones are outlawed, only outlaws will have drones.
