Not that this does or does not have anything to do with this particular situation........ I beg to differ. Many decades ago, while flying an 11ft wingspan, high aspect ratio R/C sailplane, I experienced an incredible thermal and coastal inversion layer effect that took my 4+ pound sailplane to an incredible altitude. All the while I was trying to "ease" it down. It finally got so high, I could barely make out its attitude. The only way I got it back was to put it into a vertical spin! That's a 4 pound sailplane!
Just my 2 centavos.
