In reply to plyometrics:
my first suggestion would be

there's also loads fo tips and tricks on youtube
regarding battery life
with all these multirotor fliers, you have to remember all the weight is carried by the rotors, the longer the battery life the more power you need to lift the extra weight. it seems most people who run these cheaper (and yes, the phantom is a "cheaper" one lol) tend to have multiple batteries
you could buy an enormous 8 rotor machine that'll carry a gimble mounted DSLR with goggles that allow you to see the output of the camera "live" but they are several grand.
a quick scan of the advice on the above forum seems to suggests you'll need
a phantom
a few spare batteries
a lot of patience to learn to fly it well
some ND filters, a vibration isolating gopro mount, an aftermarket prop set and a balancer to make the footage as stable and jello free as possible
so including the cost of a gopro black edition you're probably looking at nearer a grand
i'd love to get one but can't justify it at the moment
