A young inventor from Prague, Jan Kokes, contacted me a while ago, saying that he had invented (actually filed a patent application) a completely new fletching invention, with huge advantages compared to the common vanes. I was interested of course, but then I did not hear back from him for a long time. Now he sent me an arrow with his "turbine" vane! That's right, a single blade, much like an arch... I could not believe it, but the thing flies amazingly straight and I think it is also faster. The spin rate is really high. Can't wait to shoot some 1000 fps material of the thing in flight! I have a feeling we are witnessing the next big thing in arrow technology.
