Spent first 2 days with my new bumblebee and made a video as a result. I really love Spark and only these "falling from the sky" cases are frightening. I only hope that DJI guys working hard to investigate these cases and improve firmware to prevent them.
Indeed a great video that very well demonstrates the true capalities of the Spark! Makes me a bit shy now to publish my first Spark video from a month ago, but I'll do it anyway ;-)
