I need technical assistance for DJI Phantom 2. I have never flown the MC. Yesterday would have been first flight, but it wouldn't compass (GPS) calibrate. I tried and tried the GPS dance. The horizontal calibration works fine. But the vertical when complete returns to slow flashing yellow. I did the software calibration, and all is fine. But the vertical just will not calibrate. So I decided to at least start the motors any way for the first time, even if I can't fly. The motors will not start on GPS mode nor on ATTI. When I push on the sticks (in any of the combinations) to start... the red LEDs on the MC blink 5 times, then it returns to slow flashing yellow, and nothing happens. The motors don't start. Help!! I've included images to show everything is fine software/ firmware wise. I don't know what to do.
