Most people I've talked to got scared! But, let me let you know, it's a process of getting experience.
To fly up to 400ft. and see your Lil' Mavic look like it's too far, and going to fly away can cause heart palps!
The worst is, flying your drone by eyesight to a distant spot. Then looking at the remote to adjust the gimbal, etc, for a photo,
taking the photo, then looking up to not be able to find your drone! Panic can ensue!
But, let me tell you the secret, of overcoming this. There's no problem! Your Mavic will just hover, if you let go of the sticks.
Look back into the controller's screen (phone/Tablet), and take a look around!
I know you are supposed to keep your eyes on the drone, but that is the cause of panic.
Take your time and pretend you are flying inside the drone, like a video game.
You'll see clearly where you are, and can probably spin around, and soon find the little man on the ground holding the controller! LOL!
Just make sure you have good altitude, and fly back towards him. (You).
Pretty soon you'll hear the drone approaching and be able to find it in the sky, and take over with visual flying, to land.
Of course, the best situation is to have an observer carefully keep track and let you know from their vantage point. But the best calm feeling is when you are just watching your flight through the camera gimbal.
An observer allows you to fly like a bird. There are still things to be concerned about, but the scare factor will be replaced with awe. Aloha!
