Like I said; Do not rely on these automated features! Precise landing/take off, RTH, follow mode or whatever, trouble...only trouble.
Now, that's a bit rigid, don't you think? Give some thought to all the automated technology you're still using when you land "manually". Or "manually" fly in a straight line. Who's holding altitude? Maintaining orientation and direction?
When you do land, do you really fully control the landing manually, or in fact do you simply hold the stick full-down while the aircraft flares itself and gently settles on the landing surface?
This is just scratching the surface of all the "nannies" that are really flying for you, so a bit of humility is in order here in terms of belief one is a highly skilled quad copter pilot. And that using but one or two more layers of technological assistance is somehow the demarkation of the lazy or careless amateur.
Go build yourself a quad from the early days, without compass, IMU, baro altimeter, GPS... Only a relatively primitive "flight controller" to apportion power to the props in response to stick movements.
Fly that for more than 5 seconds without crashing it and come back. Then, fly big figure eights over a high-school football field, holding constant 50ft altitude, on a breezy day and we'll give you the Experienced Pilot star.
Otherwise, giving high-level commands to these AI machines so they can do the actual flying and perform to our desires isn't really that much different flying autonomously (RTH) or landing manually. You're still only indirectly in control regardless.
