I suppose if he was to actually start it up, he would ask people to stay away. He is just sitting in it for the photo shoot. And wooden blades might not be so

I suppose if he was to actually start it up, he would ask people to stay away. He is just sitting in it for the photo shoot. And wooden blades might not be so crazy. Apparently, the Bell 47 heli uses wooden blades, and the Kaman K-MAX use a wood/fiberglass construction for the rotor: http://en.wikipedia.org/wiki/Kaman_K-MAX http://en.wikipedia.org/wiki/Kaman_K-MAX Smaller props for airboats and such are sometimes made of wood, but the stresses involved might be different. I know model RC helis often use wooden blades too, but the difference in scale and safety requirements would make that a moot point, I guess.
