if you have updated to new software, you have to activate the motors my pushing both sticks to down and out or down and in,, then push throttle to mid-point and phantom with throttle up and lift off to around four to six feet off the ground and hover there, you can do this in gps or attitude mode.also you will get two green blinks till throttle is at mid-point then a single green blink,, make sure you watch the videos and tutorials on youtube, they help a lot.
