Hello. I´m new on this board and also a new Phantom 2 owner. I´m from Sweden and I hope my english is good enough so You can understand my problem. I have had my Phantom for almost one week and haven´t take it out for a testflight yet. When I got it, everything worked well and I downloaded both the Phantom 2 assistant and the RC system assistant from DJI:s download site. Then I upgraded all firmware that needed to be upgraded. I have done all the nessecary calibration and now, the engines refuses to start. I have searched in every forum for some tip on how to solve this but cannot find any solution. The leds on the Phantom are blinking as they should, one green and 3 red, because I have it indoors and therefore it cannot find any satellites. When I said that everything worked well at the beginning, I ment that the engines started and I could get the aircraft up in the air, not more than I could controle it since I was in my livingroom. Is there something I can do to put everything back to factorysettings. I´m sure nothing has happened with the maschine because I haven´t crashed it against anything. Just a few smooth landings on my livingroomfloor, up for about one meter and gentlly back on the floor. I have the zenmuse-version and the gimbal works perfect.
