Hovering on the deck a few feet away is really no different than any other RC flying we have been doing for years. First the loop, then the roll, then inverted flying and knife edge. Pretty soon the better flyers were doing these things right on the deck. It was once cool to see of you could scrape the rudder on the runway while making a low inverted pass. Our planes are better today allowing the 3D style of flying.

If we regulate this style of flying out of our hobby, so goes our best flyers. It's like asking a really good down hill skier to stay on the bunny slope. Like Taylor said, the better pilots are finding new ways to get their adrenaline rush.
