Thats crazy! Does it use a regular propeller?
Any idea how big that room it is flying in?
It's an electric engine. As you can see, the propeller is encased in the wings and fuselage, very well protected. Huge flaps/wing ratio...
I've once seen a similar demo with a more classical model plane with a gas engine. The guy literally just settles his plane on thin air at the beginning, and grabs it by the fuselage at the end, while it flies suspended under the propeller (and you have to very very confident to put your hand that close to a spinning "open" propeller)
