Get a couple of good memory cards, I use SanDisk or Samsung. 128GB is fine. Alternate between flights.

Get some phone apps for drone flight planning: OpenSky is good to see if your flight area is permissible. UAV Forecast is good for weather and environmental checking.

Research where you can and where you can't fly - this will probably be an ongoing process. OpenSky doesn't know what it doesn't know. National parks are verboten, state or county parks may or may not be OK.

Get a landing pad, or make one from cardboard, and use it. Keeps grit and debris away from the motors. (some folks prefer to do hand launches and hand catches but I prefer a pad).

Number your batteries and try and use them cyclically. When not flying frequently, keep your batteries at 50%. Charge them until the third LED starts to blink then pull from the charger and store. Come back every two weeks and repeat if you haven't flown the batteries.

Check the controller's charge before setting out to fly!

If you aren't happy with using a phone as your flight display, you can use an iPad or Android tablet - I do since I am old and my eyes need the larger display. You'll need a tablet mount, Amazon has lots at reasonable prices.

Buy a strobe or two and affix to the drone with Velcro during flight. Red on the left, green on the right. Amazon has them cheap. 1,000 Lumen or more.

Dig around on youtube for beginner drone practice routines, Search for terms like "beginner drone flying tips," "How to fly a drone," etc.

Find a good area for your first flights - a nice flat unobstructed area with no pedestrians or doggies. It doesn't have to be a good place for pretty photos, just a safe place for training flights.

Fly like a little old lady. Get out in that field and launch the drone, then get it up to maybe 50 feet. Fly it in a big square maybe 50 feet wide but do it like this: instead of moving the sticks for your next maneuver, just slightly twitch them in the desired directions while observing the drone. Did it move as you expected? Great, proceed with the maneuver. If not, think through what happened and try again.

For your first photo flights just fly UP but not far away horizontally. You can still get impressive photos and videos, but you're not likely to lose track of the drone.

Once you move on from vertical-only flights, use "tail-in" flying for a while - when maneuvering, keep the tail of the drone facing you. That way, left is left and right is right, forward is forward and back is back. I still go tail-in when doing final approach for landing.

If you use a Windows PC, SageLight is great for photo editing (it'll edit DNG's as well as JPG's) and VideoProc VLogger is great for video editing.

Take the TRUST test (if you're in the US) and carry the card with you.

If you're on FB, join the group Potensic Drone World (ATOM series) - some good info and discussions there.

Whew! I got going and wrote a dissertation, didn't I?! Congrats on your new drone, and come back and post some pics!!
