We were running some flight time tests today and honestly - its not good news.... Our brand new Phantom is fitted with the Following Zenmuse Gimbal Sony FPV + Camera mounted to battery door GpPro 3 Black 2250 mAh 45c Desire High discharge Battery With EVERYTHING connected and running ( including The wifi the Gopro) - we got 3:21 sec footage with the phantom giving up the ghost at 3:56 sec We then tuned OFF the Wifi and the FPV - footage 4:12 - Phantom dead at 4:44 sec We noticed that the Gimbal is charging the gopro ?? why ? does anyone know how much this impacts the flight time ? if anyone had any ideas as to how we can extend the flight time - would be appreciated Waxworx.
