I do not dismiss this research: it is amazing. But, I also think you are underestimating the skill and sophistication of RC helicopter hobbyists. There are international competitions involving very complex, but well-defined and precise maneuvers. For example, there is a maneuver named "chaos" in which the pilot continuously pirouettes while continuously flipping while continuously rotating the axis of the flip while holding the aircraft in a single position a few feet off the ground. It is tremendously difficult to even visualize this fully. The research video also reminded me of this video, where an RC pilot lands on a vertical wall (without velcro): http://www.youtube.com/watch?v=lZ2HlePbD20#t=1m07s http://www.youtube.com/watch?v=lZ2HlePbD20#t=1m07s
