Wish I could afford to build it. It would be so useful down here in the land of water. I'm going to take on a cheaper hovercraft kit, I think. They have one at that site that's around 1500 to build, uses Techumseh (rather have Briggs) motors for thrust and lift. It'll be neat as heck for hunting and fishing in the shallow back bay marshes around here, but no where near as cool as this winged thing. WOW, that'd be neat!
