Everything seems to work. The lamp blinks so it got satellites, it hovers normally and the all the controls work. This happened before upgrade to 2.0 and persists after the upgrade. It did however happened after i paired the new camera. In the assist software everything looks normal even the battery stats are there. have tried 2 different batteries... anyone had this problem??
