I have 4 very small electric motors from one of those toy store type r/c multi props. I can't tell the size, but i suppose they would work well if some one need one. they produce a fair amount of air from a tiny battery pack, a skilled person could certainly do somethin with them if interested. P.S. I now take back EVERYTHING I said about not having much to offer, you dont know what you have laying around until someone needs it.........
