If you switch off the GPS-assisted flight mode, it'll do 35mph. With GPS assist on, I would imagine 20-25mph. The stated range is 2km (1.25 miles), but I've heard of similar drones getting out as far as 2-3 miles before losing connection between the controller and the drone. Keep in mind, it's broadcasting video at 720p back from that distance to the controller which you can view on an attached tablet. That's pretty crazy if you think about it. If you completely lose connection between the controller and the drone, the drone is programmed to automatically fly back to you (in theory).
