Those old drones are not bound and can just be sold and logged in with a new account. It's mostly on the Fly app with newer drones from Air 2S that were bound to an account.
…and the LIDAR is only forward facing, but that is helpful enough with barely sufficient light to see where you are flying. Just don't get too creative and fly backwards or sideways or even straight up!
If you are the original owner, on the new RC log enter your old email used on the previous RC then select reset password. This should allow you create a new password and use the drone IF you are the original owner.
