Just this morning i upgraded my DJI Phantom 2 to the latest Software. Everything fine. After starting for a Testflight after 20 seconds the DJI (GPSmode , calibrated, all lights flashing as should) just took off and crashed in the Atlantic ocean. Total loss, and no idea why !!!!! As I wont continue with DJI Phantom I have now plenty of parts available. special props, landing gear, monitor, travel case, batteries, Control. If someone is interrested in the stuff , pls leave a message .
