Hello all. This is my first post since this is my first dilemma. Ive been flying my P2V+ since Aug. After the latest update I noticed my rear lights are flashing yellow / green. It acquires GPS with no problems and flies just fine. If need be it can find its way home. I understand the sequence of yellow / green if for warming up and it shouldn't fly. However it does fly and fly well. What do you think? Should I be concerned?
