It is a pleasure to welcome you to the Mavic Pilots forum.
I hope that you will be able to use the forum to further your safety knowledge and for the exchange of innovative ideas and as a resource for current developments in Mavic quadcopter’s.
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.
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 kitten or puppy 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, 4-5 feet (1-1/2 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.
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 Mavic Pro Platinum. You will also find the 65-page User Manual, in case your Drone did not come with one.
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…"
