The first video in the series was filmed in mid-December 2016 and it was colder than it looks!

The temperature was only 4°C and to further complicate matters we were forced to film much later than we had planned, as the drone batteries need to be at working temperature before the little aircraft can even consider taking off. Much warming of icy batteries next to bare flesh took place, though I think the resulting aerial images are well worth the discomfort endured!
