First time out with the precious drone. After all the prep , reading and checking went to the beach this evening to try the first flight. Did the calibration and slow green lights so ready to go. Had great flight took it easy at first then tried some altitude in GPS prob 100ft, then some down range and manoeuvreing . When battery got to 1 light I kept it close to see what happens . Well lights went red and it started to randomly fly away! Obviously I **** one and hit rth, it luckily worked and very slowly came back, did seem as if would never come down it was that slow. I was expecting red lights flashing and to still have control. Anyone else had this. What strange is it was hovering about 30ft then when red lights came on it started to fly north?
