Those are pretty sweet, only down side with something that big is the inability to move the thing around, imagine with that virgin galactic one they have to take the wings off and still need a truck to move it around. Not an issue if you're already a pick up guy or whatever but probably can't throw it in a backpack like my quad. They are super nice looking though and fun to watch fly, have a buddy at work who does fixed wing (fighter jets mostly) and we're slowly but surely pulling him over to flying quads too. Think the closest I ever came to flying fixed wing was one of those wire attached fixed wing planes (appears they are 'vintage' now)
