Racekraft props on a Vortex 1509 March 2018I have a Vortex 150 and had almost used up all of the original props and I thought a little experiment using different props might be worth trying. The props are as shown in the photo the 4 blade Racekraft props. I found a slight increase in punch at the expense of flight times for a racer this is great especially a quad like the Vortex that is heavy. I think that these props are worth getting if you are racing, an added benifit is that the prop noise is significantly quieter. The props have been impact tested by me on some small branches when I am flying my way around trees. The props can handle a little rough treatment. I like these props better than the originals. A big bonus is that they come in purple.
