Seehttp://www.youtube.com/watch?v=fWoLsJz8J5U Compared to a real airplane, yes. There may be some niche applications, like unmanned surveillance, where they might be useful but they are terribly fragile. And a range of 90 minutes.... That's barely enough to start a crosscountry. If you want a fun machine that goes places cheaply The Bantam B22 Microlight has a 4 hour range at 60+ knots. I was referring to the unmanned research things that stay up for days, mostly because they are little more than gliders covered with solar cells with an electric motor. Correct. Those are aeronautical physics experiments. They are unmanned to set records in duration and elevation. No they are unmanned because they would have to be many times bigger to carry the weight of a person. -- Jim Pennino Actually you could carry 2 or 3 people. They are unmanned to set records in duration and elevation. Where would you put them, strapped across the wing? Well, since there's sufficient lift to carry them, you would design accomodations. But they didn't build them to carry people. They were trying to set records in endurance and elevation, within the criteria of the original mission statement which sought to display it's applications in mapping, etc. Nope, they built them to keep researchers employed. They serve no other purpose. As a UAV they are a dud. -- Jim Pennino Remove .spam.sux to reply. |
