I was flying last time a few weeks ago, and no problem, everything was working fine.
No when I try again, it wont take off. The leds are flashing green (about ones every second). I have GPS connection, everything is fully charged.
I can controll the camera upp and down. I can flip the S1 switch to enter compass calipration, and the calibration workes fine. When I try to start (both sticks down) nothing hapens, except the leds are making double flashes, still every second, still green but 2 quick flashes and off for about a second, 2 quick flashes etc.
I did calibration on both the Phantom and the controller. I'm still in mode 2.
Enyone who have an ide ?

Sounds like you should re-link the controller to the phantom. Details in the manual and it is dead easy. Be aware that the little re-link light is also the button. Hope this helps.

try to download DJI RC System Assistant_1.2 and use it calibrate RC. keep in touch.
