Ok Another stupid question.. I am calibration my H and what flight mode am I supposed to use? Smart mode or Angle mode or doesn't it make a difference This is for Compass and Accelerometer I did the compass three times before it took. Second time it showed the green light in Smart mode. but when I looked at the controller, it was black and did not return to a viewable screen, I had to turn everything off and start all over. What happens if this happens while flying ? Short reason for Questions...I just got my H back from Yuneec repair and I want to make sure I am doing everything correctly so I don' t have to return it again and wait another 3 weeks to fly !
