Yes. My Pluma. Not intentional, but it did happen at a SLAM event this summer. I had a 9 amp ESC on a motor that peaked at 10.3 and browned out in a vert maneuver. I had programmed the ESC's failsafe to give full left rudder (set up for a small indoor gym). Noob mistake. I only had aileron and elevator control when I browned out and that Pluma did a flat spin from about 100' to terra firma on its gear! Lots o people to view the "walk", MAAC Prez was there too! Swapped the ESC out and flew it again, just won't try it again, especially with a bigger bird!
