Very cool! I didn't realize an autogyro ever had the blades driven, but I guess they do. Went to the Wiki here to read about it: http://en.wikipedia.org/wiki/Autogyro That might be a trick to get running in a small model. Seems like it would also be a trick to fly. Sure looks like fun. ...Tiger
The first time I viewd the video I thought it was a full size and a person was going to get on board. I think the first "Little Nellie" I ever saw was from the James Bond movie "You Only Live Twice".
