Flying a drone for the first time can be a little daunting....take it from me i know.
The drones available from DJI make them in such a way that you can literally pull them out of the box, charge the intelligent flight battery plus controller, install your propellers, download the DJI Go app and fly it.
They are that simple.
One thing that i do recommend is to view the DJI video series which certainly helps you along the way. I've put them all in one place for you with direct links to DJI's YouTube channel.
