There are several. The Vapor is pretty cool. One other that is very different from that is The Bug. http://www.lightflite.com/

I have two of them. They are a blast to fly. The pilot at the demo at WRAM a couple years ago had this thing "landing" on the wall, yeah, the vertical wall.. and nosed it up to the ceiling and held it there. Then he cut the throttle and it fell to the ground like a leaf, bounced once or twice. He walked up to it, turned it over, and flew away. Very cool.
