I guess the big difference is that the first one is "commercially available", which means mass production and certification for mass usage.

QuotePrice? Reportedly, around $100,000.

Quoteat $86,000 it is pitched at the level of a high-end car.

why not get a 100cc ,model,and fly with it

Yes, we can buy something like Ankur said, from the site http://www.ultralightnews.ca/lilbuzzard/lilhustlerss.html

why don't we get a 100cc heli

anyways i think that the jetpack will be helpful to find lost rc planes
