I picked up this plane at Narita airport ( Hakuhinkan Toypark ) on 20/Oct/2006. I paid 2625 Yen.
Here is the Japanese website on it.
The package has the plane already assembled, I only had to get batteries, charge it and start flying! It uses infrared for control, thus flying outside is quite challenging due to the sun's IR rays ( and the occasional breeze which sends it tumbling uncontrollably ). Yes, it is an in-door plane, but for that, it's superb!
It weighs an unbelievable 3.5 grams, made mostly of styrofoam.
It has a tiny electric motor and an electro-magnet controlled rudder. Charging time is around 40 seconds which gives about 30 seconds flight time. Turning radius is around 3 meters.
That electro-magnet is tiny, yet works unbelievably well! Check the below movies for demonstration:
