Rotor speed is determined by the positive pitch in the rotor and the load on it. Thus the reason it speeds up and down in and out of a turn. The reason Dragon Wings were built with tip weights was to have higher inertia of heavier blades but not the all up weight. He started with 4in of brass. Then later put 8in and 12in. The 12 in of brass were marketed as cruiser blades as unlike the 4in weighted blades would plow through thermals like a dump truck. There was a trade off though it is not like a sports car any longer. If you try to do tight turns and switch back between left and right tight turns too quickly the stick will shake and it gets heavy. Dragon Wings are very light compared to other blades on the market but still give you a little extra on landing. A 22’ set of blades with 4in tip weights weighs only 43 pounds for the whole disk.
