RaceKraft props are a PC blend making them nearly unbreakable. With this lower pitch prop, most freestyle fliers feel more "resolution" throughout the throttle range. And because they are not bullnose, they're easier on your batteries.
The RaceKraft 4040T come from the same factory and mold as the old Quadrysteria Bashers.
Excellent balance out of the package.
