This is the same angle-of-attack (AoA) adjustment system as found on the Blade IV and Blurr kites. It lets you adjust the kite's AoA by moving the adjusters larkshead knot up and down a row of preset knots. Increasing the AoA slows the kite and ads more grunt and lift; reducing it lowers lift, speeds up the kite and can improve up-wind work.

This kit is meant as a straight out retro-fit for Rage kites, but should work with most fixed-bridle kites with with three rows (A-B-C) of bridles attached to the main lines. This kit is recommended for experienced kiters who do not mind "experimenting". Results cannot be guaranteed and may vary from kite to kite.
