I just got my phantom and I'm totally hooked. I got 5 batteries when I first bought it. I think I want to get like 10 more. Is that crazy? I don't get a chance to drive out to the nearest field and fly the phantom around, so when I do get a chance, 40 minutes of flight time just isn't enough........Right now, I'm just using the GoPro,no gimble(yet). Does anyone have more then 10 batteries in their reserve?
