Drones have always been fascinating to me. I go to the extent of downloading diy videos hoping to build one for myself someday. Nice post bro. In the future, we cn start sending gift boxes and hand written letters to each other via drones lol... but when these things become more common, maybe there'll be avenues to charge them while on air or what happens to them when the battery suddenly runs down?
