I've been flying my Spark same various local locations since I purchased it about six weeks ago. Suddenly today all I get is the No Fly Zone. The president is staying in NJ for several days which is only about 45 minutes away from here. Is it true that a NFZ umbrella goes up for a distance from that location? If so, do they remove it quickly when he leaves? I know they put up NFZ in areas of forest fires etc. So in any case is there a way I can check to see if its malfunction of my spark, a new permanent NFZ or a temp one? Any suggestions welcomed...I am new at this.
