Ultra-Light Micro Air Vehicles 143
Roland Piquepaille writes "Dutch engineers have built the third generation of the DelFly autonomous air vehicle. The DelFly Micro made its first public flight earlier today in Delft. This micro air vehicle weighs only 3 grams and has a wingspan of 10 centimeters. This very small remote-controlled aircraft carries a 0.4 gram camera. The DelFly Micro, which looks like a dragonfly, can fly for 3 minutes at a maximum speed of 5 meters/second. It could be used for observation flights in difficult-to-reach or dangerous areas."

That's exactly what I was thinking! When I was 12, and I read Raymond Abrashkin's "Danny Dunn: Invisible Boy", I was mesmerized. And this mini UAV is essentially the plot device in the book, right down to the dragonfly appearance. Pretty good prediction for a book from the mid '70s.

I think a really good example is this guy's plane [youtube.com], he made it to be as light as possible and had to make his own motor for it. I think they should make one the size of this 'dragonfly' but with a propeller like the plane in the video.

They're 50% longer and wider (so not much bigger), but they are 5 times heavier - 15g.
They look like this:

(I didn't buy it from there though - it's just a link I got from google).
Trouble is the quality control is not very good, so either you get it at a shop where you can test it first, or you'd have to risk getting a dud. And even if it seems to work, there's no guarantee it'll continue to work for more than a few days.
I've got three, and one is faulty (it still flies but the motor or something is not smooth- blades stop spinning nearly immediately when you cut the throttle). And some of my friends had helis that stopped working after a few days (that said, I don't know how well they treated their helis
The ones that work are pretty good fun. 3-channel = up/down, turn left/right, forwards and backwards.
Of course, they're not going to fool someone into thinking they're some insect. But the delfly micro doesn't fly like a dragonfly either. The only insects I can think of that fly like that are some moths (the larger ones).
BTW the summary appears to be wrong - the delfly does not seem to be autonomous at all - it is controlled by some human.
When I think of it, it's quite amazing how behind we are in tech- dragonflies are smaller, fly faster (50kph), fly for longer, are more manueverable, and are genuinely autonomous - they find their own "fuel" and even reproduce.

Radio control micro planes have been built here in the US by hobby people that weigh LESS than 1/2 gram

Actually, the first tests they did were inconclusive. They revisited it and eventually did find that frozen chickens had more penetrating power than thawed ones. The final test that was conclusive was several sheets of glass, and the frozen chicken broke more panes than the thawed one.

There's also this new one [thinkgeek.com], which is basically the same size as the DelFly Micro, can hover, and has double the flight time. It doesn't have a camera, though, but considering TFA claims the Micro's camera only weighs 0.5 grams it would be easy to add one.
