Just purchased a 2010 Rebel (hope the kite lives up to its god-like reputation).
I'm going to assume the bar is all stretched out and could use some advice.
I see the outside lines are like most kites, but the center lines consist of a Big Y line and a smaller Y line above the bigger one.
How are these tuned?
Should ALL lines be the same length when the kite is fully powered and held against the chicken loop?
If the centers are severely stretched out and there are no more knots to lengthen the outside lines at the bar ends, do you begin to shorten the centers with knots?
If anyone has any links to North tuning I would appreciate it.
