With all foil kites they require some basic maintenance to keep them flying their best. After some time as the bridle beds in it may need some adjustment. We recommend always starting by making sure flying lines are equal length and the yellow sparepart lines which run through the pulleys are not too worn. These shrink with use and affect the kites performance. They should be inspected regularly and replaced when they show signs of excessive wear.
Once you are happy with the flying lines and sparepart lines it is time to look at the mixer. Here FS founder and designer Armin Harich explains how to perform the mixer test on your SOUL.
