Slick video all right but I was thinking the same things echoed here...
If we wonder why the RV community is sometimes thought of by other pilots as lawless, hot dog, renegades, another video like this simply confirms it. Good judgement seems to be left in the hangar unfortunately sometimes. Repeat some of this stuff enough times and you might become another accident statistic and one wonders if this guy knows the regs at all.
BTW, I recommend some more dual on the landing phase- scary technique on an A model.
