If your kite is spinning you can be almost sure the brake line on the side it is spinning is being effected somehow.
Check all lines are equal in length.
Check the bridle for issues.
Check that the knots are equal on handles + at kite.
Start with your brake lines as long as possible. Both should have a bit of slack and arc while flying. Once it is stable on front lines tune in your
brake lines so that you can back the kite down but they don't come into play without your input.
