Welcome from the Hampton Roads area of Virginia, USA.
As a Returning New Drone Pilot, there are a couple of Legal Things you may need to do…
You wrote that you renewed your “license” so I do not know what license needs renewing within an 18-month period, perhaps you are not located in the USA. In the USA, a TRUST Certificate does not expire and a Pat 107 Certification is valid for 24-months and only has to be made “re-current” with a FREE short test…
If you have installed the Larger, Extended Range Battery, It increases the weight of the Mini 3 Pro over the 250-gram weight and it would then be required to be registered.
If you are not located in the United Sates, then you would have your counties’ rules and laws to uphold…
If you are in the USA, then this is a link to the TRUST Certificate at the Pilot Institute Web Site (FREE…)
And again, if you are in the USA, here is the link to the FAADroneZone (Optional Registration for Drones under 250-Grams…)
In the posting by @msinger, he has given you a great lead of advice and my posting (mostly a boilerplate…) repeats some of his advice and offers some more…
So, even though you have already been told some of this previously, it’s still some Good Old Fashion Advice…
You paid a lot of money for that Drone, put your phone number on it. If your drone gets lost or stuck in a tree and it finally comes down when you are not around, give the finders an opportunity to contact you so it can be returned.
Now, for the Fun Part, But do not let the excitement of the moment get the best of you. When you are going out to fly, do it slowly and deliberately. Get used to a set procedure and even practice it.
There are so many things I could write but these are the highlights that I feel need mentioning.
Plug in your phone/tablet into your controller; turn on the Controller and DJI Fly App (if it does not start on its own…). On the Drone, open the front legs, then open the back legs, then remove the Gimbal Cover.
The Gimbal is the most delicate item on the Drone and banging or bumping can damage it. I also fastened a short “Remove Before Flight” ribbon to the cover so it’s more noticeable and I do not forget to remove it…
Turn on the drone and watch it come to “life.” Watching the Gimbal go through its self-check is almost like watching a puppy or kitten opening its eyes for the first time…
Place the drone down (preferably on a Landing Pad) while it finishes its self-test (collecting satellites, etc…).
Check your battery status (Phone, Drone, and Controller), check the Signal Strength, by now the Controller should have reported it updated the Home Point.
Lift off, 6- feet (2-meters) or so, hover a bit, check the controls (move the drone a bit forward, back, left, right, yaw left and right). By now, your Controller will probably report again, Home point Updated.
Now, here is the most important advice, STOP and take a few deep breaths, let the nerves calm down, your drones not going anywhere, just look at it and enjoy it for a moment, once you start moving it, it gets all types of new excitement because the memory of your last one winding up in a tree will flash back and you need to relax…
You should establish a routine when you fly. If you go out in a rush and race thru your start up and take off before the drone has finished it prep, it may update its Home Point over that pond or that old tree you are flying over and in your excitement, you’ll fly the drone long past it Low Battery point and when it engages Return to Home and lands in the pond or in a tree; it will be all on you…
Now go have fun, learn to fly the drone by sight before you try to fly it out a distance depending on the video feed, FPV.
I would also advise you to use YouTube and watch a lot of the Videos on flying and setting up the Drone. When it is too dark, too cold, or too wet, you can “fly it vicariously” through YouTube. Also watch some of the Blooper Drone Videos and learn how not to fly your “New Baby.”
Below is the link to all of the downloads offered by DJI for the Mini 3 Pro, including the User Manual.
After you read the Manual, read it again, you will be surprised what you missed the first time and you will be better prepared for that first “scary moment…”
Fly On and Fly Safe…
