You're both right.
It isnt a true lawnmower, and it isnt a photoshopping job.

I seen a housefly, I seen a horsefly, I seen a butterfly, heck I e'den seen a draaaagonfly, but I done seen everything, when I seen a lawnmower fly!
Dumbo, the original "whatzit" that could fly. In Dumbo's case flight should have been an impossibility. How can an elephant...fly? I guess it wasn't too hard otherwise no story. Take an object, er elephant, now stick some wings on him, in his case giant ears. Now add some thrust and gravity. Add a little lift and control to the equation...you have flight.
When I first got into the RC hobby I took a look at the Sky Cutter, I thought that was right up my alley, something that should not fly that can fly. Sounds just like the Dumbo story. Then I looked into it even further and saw that FlyingThingZ carries and entire line of products of "thingz" that should not fly, that do fly. Just like Dumbo, they designed their airplanes (strange to call these airplanes) to make the impossible, possible.
I finally got too see one fly at an full scale airshow. There was a mid day break where all the RC planes came out to fly. Giant Edge's, Ultimate Biplanes and lots of other beautiful RC aircraft. But then someone decided to whip out the Flying Lawnmower and the entire crowd got on their feet in amazement. No a $6,000 RC 40% Edge really didn't do anything for them, after all they just got done watching Kirby Chambliss put on a show of a lifetime. They were more intrigued by the flying lawnmower much more then the big 40% Edge. I knew right away I had to have one and quick, it looked like a blast to fly.
As soon as I got home from the Airshow, I called them and placed my order so I could find out. It wasn't just about getting the plane to fly, it was about putting the kit together so I could see what they were thinking in their design. Well I got it so now you are going to find out what makes the impossible, possible!
