Okay, I'm cheating, this is using a GoPro on the wing strut of my Husky, flying the canyon faster than I usual do, so the turns are wider and I'm higher in places due to the wider radius turns. This as it was a turbulent day so wanted to stay well above stall speed. Skip to 4:00, turn sound down. I flew this in 2013 before much FPV and the advent of many more capable drones. There are a number of drone videos taken along this stretch, so I'd be more cautious flying this now, - wouldn't want to trash someone's drone.
