Charge everything.
Do a Firmware update
Do you first flight somewhere in the open, no metal, no cars, nothing to crash within 50 feet on any side.
Make sure your return to home height is sufficient. I like 50m better for my area, shrug.
Do NOT throttle up and take off until you get a GPS Lock visible on the controller.
Start props, take off, hover, land, till you're sure you got that figured out.
Practice moving the drone around, then turn it 180 and do the same until you get comfortable with reversed controls. If you do this at 6 feet or less over some grass, a crash won't destroy it. Might lose a prop, but the drone will live.
Keep the gimbal cover on for your first few flights at least.
If you lose sight of the drone for whatever reason, send it UP at least 50 feet then use your forward back until the distance on the controller decreases. This way you know if it's coming back at you.
If you get all confused and it's not going where you want, STOP, let go of the controls for a second, take a breath then ease back on them.
By your second battery, you'll be much more comfortable.
It took me a number of flights before I felt comfortable enough with this drone to send it more than a few hundred feet away from me and I have other drones I've flown for some time. It was simply a matter of the drone earning my trust. It doesn't take long though, assuming its working as designed.
Have fun!
