I live 4 miles from an airport that is class E starting at 700ft. So I am in class G airspace up to 700. The airport manager gave me his email address for notification purposes so I simply email him with time and place of flight (that is usually within 2 to 5 miles of the airport) and he always replies with "thanks for the advance notice" with a reminder to stay below 400ft. The question is will the firmware update allow my drones to fly without a hassle. I don't want to update and do not want to purchase a new drone until I know. Will appreciate any advise.
