So far he just has three and the stack flys beautifully in light winds. However, when the winds pick up the stack has a pronounced wobble to it. We think that his train lines are too short (5 ft.) and the back kites are picking up turbulance. This seems to bourne out by the fact that the stack stabilizes when put into a spin, we are theorizing that the spin brings the stack into clean air. Can anyone tell us if we are possibly right, or if we are completely off base? how long should his train lines be? I seem to remember a post whick suggested 1 1/2 times the leading edge length as a good starting point. Is this right for the Hawaiian?

I think that works out to about 54" for Hawaiian's. As you build your stack you may want to shorten the link lines even more. This will reduce some of the tremendous pull that a stack of those kites will generate. I find I can safely fly big stacks if I shorten up those link lines. Hawaiian team kites have 13 sq. ft of sail each! times 3 kites = 39 sq. ft!

You are on target, there is suppose to be a formula for this, but I can't remember what it is, possibly 1 1/2 times the width?

Dave Gomberg's book "Stunt Kites!" is peppered with quotes. On this subject it has the following pair of quotes: As a general rule, the best length for train lines on a large stack is the length of the kites's leading edge. (Lee Sedgwick) Sedge lies! None of his train lines are that long! (Al Hargus III) Andrew -- New to rec.kites?
