Started controller and wifi
Started Phantom, all four leds of the battery are green
Phantom beeps and do warmup
Backlights are green after a short while
Started app and the app tells me that everything is OK and the Phantom is ready to fly

Used the sticks to get the Phantom in idle mode and then the left stick to hover up, but nothing happens. The props turn a bit stronger than in idle

In the Assistant I callibrated the sticks and the IMU callibration.

Nothing helped

Do I forget something ???

Nothing forgotten. I would set up and do a full IMU calibration the the nRemote and sticks again. Then outside do the compass calibration. After that she if she will lift off.

You could be in MODE 1 (unorthodox)
Make sure you on MODE 2 (RC standard).
You can change this in the RC12.

And make sure you do NOT have any in REV (reverse). Make sure all sticks are NORM (normal).

The last option was THE option. Looking at all the video's on Youtube, the allways used the left stick for throttle. Indeed mine RC was in Mode 2.

Thanks both
