Modern drones are capable or returning to their take-off location, or a set location; even when connection with the remote control is lost.
They will fly to a high distance, and orient back towards home, and then slowly fly down.
Allow us to set a home location so if we lose connection with the drone, for whatever reason, it will return to home.
Other features could be obiting a set point, or following a player.
Modern drones are capable of these things and It may be fun to implement.
I think at a bare minimum they should sit where they are for a few minutes and then return home. Sometimes dumb things happen like you disconnect or accidentally hit the spacebar
It could be an attachment that is expensive but useful.
