We have a flying lawnmower that we put together for an RC airshow. We made a skit with it and it really got the folks attending the airshow a real thrill. They were wondering what it was when we rolled it out.. then, once we started to approach the flightline, I heard several in the crowd say "Hey, they are going to fly that thing" and up it went. We had a blast with it as did the crowd.
