Until battery tech improves, I'm going to give this a pass. I just can't see a 12 minute enjoyment window in any device as adequate. I wonder if adding an extra/bigger battery would have really been the difference between it flying and not flying, or if they just wanted to sell more extra packs.
The battery is actually a 3S 1000mah LiPo battery. There are higher capacity packs with the same dimensions that can almost double the flight time.... don't know about the effect on the warranty though.
The fact that my last post got downvoted makes me sad. People are actually willing to cope with a 12-minute window of power? Seriously? It's people like you that settle for crap like this that is the reason they keep lowering battery standards to get us to keep buying expensive high-profit-margin extra battery packs.
