I always hand catch. Avoids dirt, and looking foolish if it tips over upon landing (which they often do). Just one thing, hover the aircraft downwind from you, then walk up and catch a leg.
Of course, there will always be those who advocate hand catching and those who think you are Beelzebub's brother if you do. Find your own space.
Avoid trees. A phantom can get stuck up there and can be quite hard to retrieve.
Understand RTH, Autoland, and what will happen if it drops into ATTI mode. You could be rather scared if it happens in an enclosed space, for example - in a clearing in a forest, or beside tall buildings. If it goes from GPS to ATTI mode, the wind will make it drift and you will think you're doing something wrong. Just learn to use ATTI in a big space, and progressively get better at identifying when it happens.
Enjoy it!
