Abstract:
An extended flight system for extending the flying distance and improving the accuracy of an arrow when shot from a bow has a shaft first end having a threaded cavity for attaching a standard arrowhead. The shaft second end has a threaded rod for attaching a standard arrow shaft. The system has fletching located on the shaft exterior surface with fins or vanes resembling a shape of a triangle. The fins or vanes are located at an even distance from each other. A fin first end originates close to the shaft middle and a fin second end terminates close to the shaft second end. The arrowhead is attached to the shaft first end. The arrow shaft is attached to the shaft second end. A length of an arrow is extended upon installation of the system an equivalent of about the shaft length.
