I am not sure how many are aware of WeTalkUAV News, but that had a video about the durability of the Spark. Putting it through some odd circumstances that help understand the durability of the Spark and the Props. Interesting...was very surprised by the downwash interference later in the video when a Phantom flys above the Spark. Even fly it in the rain. Worth a look.
