The difference between auto modes on a phantom and "home built" quads is the ability to turn off stability. I know it's not a necessity, but learning to fly without the aid of the quad returning to level when you panic-release the sticks provides benefits far beyond what you get learning stabilized. The only reason I stress this here is because if you do what I did - learn first in stabilized, then try to move to something full manual, the hurdles you now have to jump over - the amount of unlearning and retraining that your brain has to go through is massive. If you learn that way from day one - bring it up for a few seconds - try to keep it level, bring it back down - all the way to ripping around your house at full speed - your skills on anything else with motors become ridiculous... You can literally do anything within the limits of the aircraft. Something like a tiny whoop that you can put in full manual and crash 600 times without breaking is a very cheap way to gain a massive amount of skill. You then fire up a phantom and it's child's play... It does everything for you, which is nice, but limiting.
