I'm loving the splattering of noobs on here of late!
First off people, read the manual, then memorise the manual (all of them) and keep up with the revisions too! Taking off full throttle is the way dji want you to take off, in fact back in FW 3.XX (for the original phantom) they changed the way the motors speed up for take off, you had to give 50% or more throttle before the motor speed would increase! This prevented people taking off to lightly and crashing the unit!
Shutting off using the CSC is a personal preference, do what you feel is comfortable, but if you haven't tried a particular method, don't dismiss it as being more difficult and don't tell people the best way to do things if you haven't tried them yourself, you may just find a bunch of veteran phantom pilots who disagree
As for grabbing them out of the air, I've seen videos of multicoptors being used and you wouldn't guess it, the pilot launches it from his hand, and grabs it on landing! Who'd have thought! Oh, this video is getting on about 5 years old now! . . .
And before that, when I was a kid I seen plenty of fixed wing rc pilots launching by hand and a couple (brave) few who would catch it!
