Of course they're not the only game in town. There's lots of companies, including mine, that work in the nano-UAV field. You can build amazing vehicle for $1,000 in parts, but it costs $250,000 to $400,000 annually to pay for the engineer who designs and tests it. (Before you think the engineer is making all that, he isn't, He's getting about 1/3 of it. The other 2/3 supports the corporate infrastructure around him.)
My earlier post was less than serious. :bangpan: I do understand that the mission of the micro UAV could not possibly be met by the toy micro UFO. And I think that all of the new UAV research and development, especially on the micro scale, is simply amazing.
