Nope. Trust me. As an RC slope flyer and hang glider pilot as well as an experienced thermal RC sailplane pilot, I can tell you that this was a thermal flight. For slope lift to work you need prevailing wind coming up the slope. In this case, the prevailing wind was blowing down the slope, which is why I was flying paper airplanes instead of my hang glider.
