Congrats.
Slow steps. Crawl, walk, run.
READ, as already mentioned. Know your bird before you take her out for first flights.
Find BIG empty field with little obstructions/interference from trees, high lines, houses/wireless, etc.
Begin with takeoffs/landings; Familiarization with controls. Beginner Mode and maintain over head heigth for safety. Fly forward 30 ft, backward 30ft; Fly sideways 30ft, left and right, Gain altitude 30ft, lose altitude back to starting point. Rotate left and right. You’re learning the movements of remote sticks to aircraft.
Now fly sideways left 30 ft; fly forward 30 ft; rotate drone right 90 degrees; fly forward 60 ft; rotate drone right 90 degrees; fly forward 30 ft; rotate drone right 90 degrees and fly home. You;ve completed your first rectangular pattern. As you become more proficient you can begin ‘rounding’ the corners with coordinated turns and begin flying circular patterns and figure 8’s.
Do this over and over until your comfortable knowing the controls. Then move on to other things. Know the RTH and Smart RTH procedures, just in case. Always go thru each setting in the app before takeoff. Watch and monitor weather; wind/rain. I use a landing pad or table, if its not too windy, for takeoffs/landings. Don’t want to stick that camera in the grass/dirt as the motors will stir dust up. You’ll know when your’re ready to venture farther. And again, Congrats and enjoy.
