Guys... Electronically defined 'no fly zones' are determined by a signal (beacon) sent out from an air control facility. They are not based on a set of coordinates which are programmed into any aircraft, including fixed wing aircraft. If your drone is receiving a NFZ signal further from an airport than it should, it is NOT because of a fault with the aircraft, but, because the signal from the airport is reaching out further than it should. This can happen for a number of reasons (topography being the most common). If the aircraft receives the beacon signal from the airport, then it's going to think it's in a NFZ. That's the way it's designed; including in full-sized aircraft. If you are receiving the signal further out than 8 miles from an airport, then you should contact the airport, or the FAA. Don't contact the aircraft manufacturer as the aircraft is only doing what it is supposed to do (stay out of NFZ's).
