Fit Flights are molded to achieve precise aerodynamic trajectory. This solid one piece design gives you the perfect right angle in your flight. No 'squaring up' flights in between throws. And the strengthened nylon shaft gives a more stable base than found in other spinning flight/shaft systems. No wobbles or bent wires. The spinning shafts are manufactured with 100% strengthened plastic resin to enhance durability and increases resistance to bending, breaking, and curving. These flights give amazing increases in accuracy and consistency in the flight of the dart. Set of 3 flights. Shafts sold separately.
