Here's the thing. If you are not flying without strobes attached you will not be able to keep it in sight much beyond 400 feet. If you have a strobe attached to the bottom you will be able to see it approximately 1600 feet. If you're in an area with trees the height of the trees and distance the trees are from you will also determine how far you can see your drone, but might also interfere with the signal.
Rather than testing for range on your first time out, perhaps you should have a less lofty goal and take it to a permissible park or open area where you can fly it around and learn to gain full control first. My first flights with my original
Mini 1 didn't fly it farther than 150-200 feet away. Once you are confident in your ability to control your drone you can allow yourself to be a little bolder. There is a recent thread about a forum member who recently crashed his drone in Brooklyn and didn't find it.
Definitely don't fly it in Brooklyn. Local ordinance prohibits drone in all of NYC.
