Flu-Flu arrows were used originally to hunt birds (and still are). When taking aim at the bird the archer must lead the bird and release the arrow in anticipation of the bird's travel path. Because flu-flu arrows fly short distances, it is easy for the archer to recover the arrow if the target is missed. Special bird points are used that intangle the bird as it flys into the into a wire harness attached to the end of the arrow.
A flu-flu is a design of fletching, normally made by using long sections of full length feathers, in most cases six or more sections are used rather than the traditional three. Alternatively two long feathers can be spiraled around the end of the arrow shaft. In either case the excessive fletching is made to generate more drag and slow the arrow down rapidly after a short distance, about 30m or so. Recreational flu-flus usually have rubber points in order to add weight in order to keep the flight slower.
Flu-Flu arrows are often used for children's archery, and can be used to play Flu-Flu Golf (where the player must go to where the arrow landed, and pick it up and shoot it again, and repeat this until he reaches a specified place).
