I am flying a Phantom weighing in at 1250g. recently my flight times have dropped to 3 minutes until red flashing light. I have a fatshark FPV, an Arris gimbal, gopro hero 3, Futaba radio, and prop guards. Really not sure why the flight times are so short. Other than weight where should I look for issues? I have stock props on the craft. Do I need to upgrade to 3 blade props? I am not as much of a fan of carbon fiber as they seem a bit more dangerous due to how brittle they are. I have been hit by the stock blades with really no issues. But not to derail my first questions, what should I check that could be causing this battery draw?
