if they are calling it an ultraligt the rules are pretty lax. I believe ultralights can take off and land anywhere they have enough room. and they don't require radios or any other electronics. You just can't go over a specified hight or in unauthorized airspace (airports). it would seem that this would be more of a ground effect kind of vehicle anyway, not to mention two fans front and back would make it unstable as all hell. There is a reason they are asking for help... Still cool though, if they worked I would want one.
