Yesterday I had a problem with the skycontroller 2. I have your upgrade for drone and skycontroller 2 black sticks (the new upgrade). I was about to fly and I was rotating the drone and suddenly the skycontroller light puts red and starts flashing and I lost connection with drone and the drone keeps rotating as I was doing. The rth worked fine when connection was lost after 30 seconds (my setting to rth). Thanks for Reading this is my first time this happen I was flying at the beach.
