Have my new phantom 2 for about a week now, Gopro 3+ Black, H3 D3 gimbal, and FPV. GoPro is fully charged when I send it out. My issue is flight time I'm typically getting 15 1/2 minutes is this what I should expect or is this a little short. Anyone have any ideas on how to extend the flight times or do I have a malfunction somewhere along the way. What kind of flight times are you guys getting with similar equipment, what are reasonable flight times for the equipment I have.
