For the previous owner, his Phantom 2, 3 Wrappers took off for 1-2 years in all kinds of weather (rain, snow, wind, strong magnetic interference, permanent flights from powerful radio transmitters for him), 100 meters above his head in the clear sky, for no apparent reason (interference, strong wifi noise, or the presence of a nearby RES). The copter itself works as intended, taking good pictures and following an object precisely. However, when flown inside, the copter may crash into the ceiling due to the sensors' sensitivity. Spinning your drone around in wide areas is a great idea =)
