That is some impressive toy airplane flying!
I wouldn't get it out of the spin before I'd owe someone a new toy.

Can someone tell me how that thing flies up side down? Hummm...
Almost ready to call bull**** on this one..

Pressurized fuel tank. High HP to Wt ratio.

Yeah, but doesn't the whirley still drive the copter down when it's
upside down? Or does the thrust come from somewhere else, a
directional venturi (sp?) or something similar?
