Greg has a Mavic Pro Drone and he wants a new tablet to pair with the controller for a larger screen. Leo says that the Mavic is a very nice quadcopter with a nice camera in it. Leo says the iPad Mini is a good one, but the standard iPad would also be good, and larger. He should look to spend between $300 and $400 for it. Sadly, Samsung has stopped upgrading the software for their Galaxy Tab line, so that really won't be a good idea.
Tim uses the iPad Mini 4 with his DJI Spark and it fits snugly in the controller. So that's a good option for the previous caller.
