If this is your first drone, I have a radical suggestion for you. Leave it in the box for a bit. Purchase a cheap starter drone, even one without GPS assistance. Learn to fly it in an open area, like a field. Ensure the controls are in Mode 2, but most already are. Get yourself confident with this drone. You will crash, this is why you want to make mistakes on an inexpensive drone. After a bit, when you feel comfortable, get out your 520 and follow WTFDproject's advise. A 520 is an expensive drone and crashing will hurt. Learning to fly without GPS will give you the skills to control your drone if things go south, which they will eventually. This is just my two cents, but from experience. Have fun flying!
