Ceilng fans. We have some. My brother down in Miami, finished a very nice scale Cub. Now he is a real airplane nut, A&P guy, has rebuilt Stearmans, you name it, big jets, small jets, etc., just like a lot of Aviation guys. He was putting the finished Cub together in his house, out of the shop. I think going to take some pictures. This is about a 83" Cub, lot of scratch built mechanics in it. He gets it together, cradles it in his arms, stands up, whamo ! Right into the ceiling fan. He was fit to be tied, for his not looking, it was a long repair job.
