I haven't got my Phantom to work properly since I bought it two weeks ago: When I'm outside the indicator flashes red and yellow. When I bring it inside it starts blinking green and 2 reds. I have performed advanced calibration. I have done the manual calibration outside. No Luck - it keeps on giving me the yellow and red light. I have been taking it back to the store twice - but everything looks perfect since we are standing inside. Thought it could be some disturbance near my home. Tried in new location - no luck. What do I do?
