After flying in my backyard for a few days, took it out to the beach this weekend. At the beach I realized I had uninstalled the app but forgot to re-install it, and due to the large size was not able to download over LTE... bummer.
Anyways, I was able to link the Spark to the RC and fly it for a bit without the app. Didn't go too far since I was not sure about the GPS status. I was amazed how well the Spark was able to handle the 10-12 mph winds. Pressed record on the RC not sure if it would record anything... but it did!
