Narrative:

Toy/consumer unmanned aircraft system - parrot south.a. Rolling spider mini drone. We were flying it outside using an iphone 6 plus; via bluetooth 4.0; and the parrot south.a. Freeflight 3.0 ios application. The application has an altitude limitation option which was on by default to (according to my best recollection) on or about 9 meters (I can't access the option to verify the value without the uas; but it was active). The aircraft was outside and went into an uncontrolled straight vertical climb. The bluetooth 4.0 range is about 20 meters; which it rapidly exceeded and lost connectivity with the controller. The uas; being so small (approximately 5 inches in length; 5 inches in width; and 2 inches height) continued to climb until we lost visual contact. The device had approximately 80% battery life remaining; and can fly up to 5-10 minutes at full charge. I do not know how high the uas climbed out of control before it began a descent. The uas has not been found. There were no other aircraft in the immediate vicinity. A brief search on[line] indicates other users having similar problems with these toy/consumer uas devices.
