I noticed that my 7.5m Frenzy was flying backward when fully sheeted in so I checked my lines. The center lines are about 7 inches longer than the outside lines. This is my first foil kite but I would guess that all of the lines need to be the same length like my LEI kites, correct? Looking at the center lines, there doesn't seem to be an easy way to shorten the lines. Suggestions?

Thanks for the help.

You can add some leaders on your brake lines to lengthen them out the same as your power lines. Over time the lines may stretch and eventually need to be replaced. Adding leaders will buy you more time. Your lines should only stretch after several hundred hours of use though.
