Geeze, most people just don't get it. These things have a limited battery life because they have a limited lift capacity. You can't just throw a huge battery on a tiny copter and expect an hour of air time. Bigger battery means more weight which means you need bigger motors, which means, you guessed it: more weight. Moral of the story is, people with a fair bit higher pay grade than most of us have done the math and science and determined the most efficient battery for the lift and weight of this copter.
TL,DR; If you don't like the short flying time, don't get into battery powered flying machines.
Yep. Anyone complaining has no idea how parts in electronics and mechanics can correlate to each other.
