Just out of interest. What sort of flying time are people getting from their visions? The reason I ask is that prior to the upgrade of the firmware/battery issue I was getting approx 25 minutes and today I have done two flights one of 20mins and the other 18 minutes. Both times recorded off the video which I set running on takeoff. Just basic stuff not going mad. Though it was cold / very cold so that is a possibility for the decrease I suppose?
