as you know old zippy died in the line of duty. dji, the manufacturer, were very polite when i asked them why zippy suddenly took off like a mad-drone but they said the data poor old zippy radioed to the controller before she died did not allow them to make any conclusions. they proceeded to offer a meaningless deal.
anyway, since there is so much travel left and we really enjoyed the footage zippy got we bought another one. let’s hope this one has a longer life.
